Vertical Gardens – Living Walls

As a NY living wall installer I just devoured Garden Up, Smart Vertical Gardening for Small and Large Spaces by Susan Morrison and Rebecca Sweet.

Humans have become very good at building up with cement and metal. We cover large parts of the planet with buildings of all sizes. We all see the value of building upwards in this way and we rejoice with each building built.

Humans are also very good at planting in the flat ground. We can make beautiful gardens and abundant farms. And of course we all see the value in that too.

But for some reason this obsession with building up has yet to apply to gardens. It is just not done. It is not part of our global culture. Most people would feel an empty back yard is a waste and that it should be planted. But nobody walks by a building and says, “Look at that wall, how come they haven’t planted it yet?”

ugly wall in need of a living wall installer

This cultural view point is global and a reflection of our inability to see nature as our partner. We think it is perfectly fine to build massive cities devoid of nature, as if humans and nature can be separated without deadly consequences.

As we evolve we need to bring nature with us. We can’t leave nature behind. People leave their home town and go to the city. Over time they may see their childhood friends back in the little town as less sophisticated than city dwellers.

In our arrogance we view nature the same way. In our arrogance we think we can live without nature. But increasingly as our planet becomes hostile to our destructive habits nature is telling us otherwise.

One of the solutions to reintegrating humans and nature is growing up, double pun intended. Better said I mean planting up. A human made wall should be seen as a dead space in need of plants.

Living walls should become as necessary as insulation and windows on a building. We can’t afford to waste such valuable real estate. Our survival depends on increasing our exposure to nature and walls are the key.

Garden-design-with-vertical-wall

Eco Brooklyn has invested a lot of time researching the best vertical wall and living wall installations for the New York environment. We have become active living wall installers for the NY area. New York of all cities, currently devoid of living walls and yet famous for building up with concrete, needs good living wall installers.

The Garden Up book is a step in the right direction. A handbook for DYI homeowners, the book discusses the many styles and techniques of turning your garden vertical. It may simply be a narrow part of the garden where the only space is upwards.

They suggest design styles for layering plants so that you can maximize your ground space. They list good plants and trees that are tall and slender.

They also cover the different kinds of living walls – non-soil systems, soil systems, pocketed structures, modular planting, irrigated, non-irrigated etc.

Don’t expect an in depth explanation of how to install large living walls. The book is more an idea book and an intro to what exists as options. It is full of wonderful pictures and easy small DIY projects. And don’t expect a list of native plants. They list lots of plants and it is up to you to make sure which plants are native to your area.

It isn’t a farm gardening book either. It touches on edible gardens but the techniques outlined in the book won’t solve world hunger.

The main benefit of the book is that is proposes the idea that gardening upwards is a viable and beautiful thing. The book adds to the discussion and cultural viewpoint that growing up is as normal as growing flat.

In todays society where building upwards is commonplace we need to catch up and grow upwards as well. Our balance with nature and the planet depends on it.

plants-on-wall

Eco Brooklyn is a NY living wall installer. We install sedum walls, grass walls and mixed plant walls. Vertical gardens and living walls is an increasing part of our business as we expand into ecological gardening, green roofs and living walls. We focus on low maintenance soil living walls that consume little potable water or gray water and harvested rain water.

We combine the living wall with other parts of the house so that the household gray water is reused to feed the wall. We set up rain water collection systems to route the water into the wall instead of into the sewer. The idea is to create beauty out of waste and ugliness. We take a barren wall, combine it with waste water that normally floods our sewers and rivers and turn the ingredients into a vibrant beautiful space.

The synergies are many – we divert water from sewers, increase the insulation value of the wall, increase the beauty, increase the flora and fauna of the neighborhood and ultimately help re-balance the human/nature relationship.

We do this with all out New York green contractor work but being a living wall installer is especially poignant since the addition of life is so startling in contrast to the barren wall we cover. Simply put, we love it!

Are Illegal Drugs Green?

Are Illegal Drugs Green? The answer is no. Reason being anything that isn’t regulated is driven purely by monetary benefit without any rules or oversight. If you think big corporations are bad for polluting rivers, think what damage a large meth lab can do. Not only do they have a lot of chemicals to dispose of but they need to do it secretly – they aren’t going to pack the contaminants into barrells and send them off to an approved waste processing plant. They are going to dump it into a secluded river. “Secluded” being another word for no humans, meaning nature.

This occurred to me when I read the cool info on this Addiction Support site. They offer fantastic info on how drugs as they are made now are not sustainable.

Clear cutting forests in South America for Cocaine production. If stopping legal companies from destroying the rain forest is hard, it's almost impossible to stop illegal companies.

As a green builder in Brooklyn we work near the Gowanus Canal, a great example of what happens when waste is not regulated. Now we are paying for that big time. The millions they saved by using the canal as a dumping ground is many millions more that we have to pay to fix it. Thank’s guys! Next time just charge me a couple cents more for the product and do the right thing.

From an environmental point of view it is a lot healthier for our society to legalize drugs. Tax the hell out of them, regulate them up the wazoo and strictly control where, when and who can consume them. And most importantly, control how and where they are made. Are they clear cutting mountains and drenching them in illegal pesticides to grow that marijuana or are they growing it in low footprint warehouses using solar electricity and city waste-water?

Parts of the US have been ravaged by illegal drug production. The local authorities admit they have absolutely no control over the gangs doing it. There is just too much area to cover, too much money and too much demand.

Parts of the US have been ravaged by illegal drug production, like the clear cutting for Marijuana growing in California above . The local authorities admit they have absolutely no control over the gangs doing it. There is just too much area to cover, too much money and too much demand.

People are not stupid. Well, that’s not true. Many are. But it is my experience from having three kids that working with them is much better than against.

Why is alcohol legal and other dangerous drugs aren’t? Makes no sense to me. Why is is totally legal for my six year old to light a fire in our fireplace and yet I can’t legally buy some pot to light up on my back porch? Trust me, my son lighting a fire is a million times more dangerous to society than my addled brain on pot could ever be.

And I don’t even like pot. I want this stuff legalized – and meth and LSD and crack – because I am a New York green builder and I understand that burning down tropical forests in Burma to grow opium is going to directly affect my life in the big apple.

I want to see sustainably grown opium in my corner store. I want it to be really expensive and I want the profits to go towards Addiction Counselling and a new swing set for my local park. Now that is something I could get high on.

Let Children Play With Fire

I once heard a study of two groups of animals, one group were in barren cages, the other group were in the wild. Guess which group had more developed brains: the wild animals. Guess which group lived longer: the caged animals.

This confirms the old saying, if it doesn’t kill you it makes you stronger. Or in this case, if a tiger doesn’t eat you, your brain is more developed. And likewise, a life free of challenges may give you a face with less wrinkles but it does no good for your development.

Now go take a look at your average school playground.

playground design

Apart from looking menacingly close to a prison it also is a prison of the senses. It is void of anything dangerous and thus anything interesting for the mind and body to interact with. It is an evolutionary wasteland.

Certainly in terms of deaths per thousand it does great. The stats are low. Thus less law suits.

But what have we lost? What is the real price of this so called safety? I argue it is huge.

Here is a great article that makes this same argument. Titled, “The Overprotected Kid” it headlines with:

A preoccupation with safety has stripped childhood of independence, risk taking, and discovery—without making it safer. A new kind of playground points to a better solution.

A playground where kids are allowed to play with fire.

As a New York green landscaper we come across this conversation a lot. Clients are very interested in creating a “safe” back garden. When we mention a water feature, instead of thinking how great an experience that would be for the kids, the client’s first comment is, “Isn’t that a drowning risk?”

The answer is yes. But I think it is a risk worth taking. Unless you are a crack head parent who doesn’t keep an ear out for your children. when they are playing outside. If you hear water and then silence then take a peek outside. Chances are your child is entranced by a tadpole rather than head first in the water. Their aren’t stupid.

Here is a photo of my back yard:

My son exploring our native garden designed with inspiration from the book Manahatta

My son exploring our native garden designed with lots of rocks and other sharp objects.

My garden is not a safe place. There are all sorts of things that can cut your skin, burn your eyes, and break your bones. It’s called nature. And it’s also a children’s wonderland. My son can climb like a monkey and run barefoot over loose boulders. There is nothing more gratifying as a father than to see my son confident in his body and with nature.

Gennaro Brooks-Church and son Cazimir checking out the arrival of bees.

We have a bee hive and the kids play freely around it. Our two year old was obsessed with walking up to the hive and catching the bees. But we gently talked him out of it. And once he did get stung. Now he is six and a master at recognizing which bugs are safe and which bugs are dangerous. Does this skill translate to other things in life? Absolutely. Was it worth the pain of that one bee sting? Tenfold.

For me being a green builder in New York is about bringing back that wonder – we design gardens and rooftops to be diverse, both in the native species of plants and animals but also in the stimuli. We throw in a couple things that require you to, say, step over a water feature. Yes, you may slip and get your feet wet. But it also adds a sense of playfulness and “safe risk” that is crucial for a full and happy life.

I have three kids and have gotten progressively more relaxed about these things. If I found my first daughter eating dog food off the floor I would have freaked. Now, ten years and two kids later, if I were to find my third son doing that I’d just be grateful he was getting protein.

Thus went my attitude towards child gates. The other day a client told me they had spent a lot of money for a Child Safety Specialist to install baby gates on all the stairs. And a Brooklyn brownstone has a lot of them. It made me realize I had never installed gates for my third son.

I had for my first child, I sort of did for my second, but with my third I just made sure he didn’t fall down the stairs until I felt comfortable enough to let him go up and down by himself. It wasn’t because I had a plan. It was more about doing what made sense – and exposing him to a level of danger that I felt he could overcome made a lot of sense.

The results are pretty cool. He has a physical dexterity I think is very good for him. See for yourself how he makes a normal (for us) trip down the stairs. He is one and a half years old.

As a New York green builder and natural landscaper this tells me that if I suggest to my clients a more diverse, slightly less safe (within the boundaries of the child’s abilities) design option that it may improve the development of their children. That’s pretty cool.

Renewable Energy Plan for New York

Let’s convert New York State’s energy infrastructure into something more sustainable. It’s a simple concept, with a multitude of benefits.  Converting to renewable energy will stabilize costs of energy and  produce jobs while reducing health and climate damage and overall improving the quality of life.

A recent study by Mark Z. Jacobson et al. finds that it is technically and economically feasible to convert the fossil fuel energy infrastructure in New York State to one that is supplied entirely by wind, water, and solar power. The use of natural gas is argued against due to the dangerous hydraulic fracturing process and the air pollution produced.  The proposed plan provides the largest possible reductions in air and water pollution, and global warming impacts.

Jacobson and scientists from Cornell University and the University of California-Davis have proposed the first fully developed plan to fulfill all sectors (transportation, electric power, industry, and district heating and cooling) of New York State’s energy demands with renewable energy. Additionally, they calculated the number of new jobs created, amount of land and ocean areas required, and policies needed for an infrastructure change of this magnitude. It also provides calculations of air pollution mortality and morbidity impacts and costs based on multiple years of air quality data.

While a wind, water, and solar conversion will result in high initial capital costs, they will be made up over time due to the elimination of fuel costs. Overall, New York State’s end-use power demand will decrease by roughly 37% and create 58,000 permanent jobs with job exchange predicted. It is estimated that 4.5 million temporary jobs would be created during construction phase.

The researchers propose that New York’s 2030 power demand for all sectors could be met by:

4,020 onshore 5-megawatt wind turbines

12,770 offshore 5-megawatt wind turbines

387 100-megawatt concentrated solar plants

828 50-megawatt photovoltaic power plants

5 million 5-kilowatt residential rooftop photovoltaic systems

500,000 100-kilowatt commercial/government rooftop photovoltaic systems

36 100-megawatt geothermal plants

1,910 0.75-megawatt wave devices

2,600 1-megawatt tidal turbines

7 1,300-megawatt hydroelectric power plants, of which most exist

To ensure grid reliability, the plan outlines several methods to match renewable energy supply with demand and to smooth out the variability of WWS resources. These include a grid management system to shift times of demand to better match with timing of power supply, and “over-sizing” peak generation capacity to minimize times when available power is less than demand. The plan also includes a solution to the current protocol of shutting down facilities during times of overproduction that includes the sale of surplus.

Currently, almost all of New York’s energy comes from imported oil, coal, and gas. This new plan looks to supply 40 percent of NY’s energy from wind power, 38 percent from solar, and 22 percent from a combination of hydroelectric, geothermal, and tidal and wave energy. All of these sources will be located in, or offshore of, New York State.

All vehicles will be replaced with battery-electric vehicles (BEV), hydrogen fuel cell vehicles (HFCV) and BEV-HFCV hybrids. Electricity-powered air- and ground-source heat pumps, geothermal heat pumps, heat exchangers and backup electric resistance heaters would replace natural gas and oil for home heating and air-conditioning. Air- and ground-source heat pump water heaters powered by electricity and solar hot water preheaters would provide hot water for homes. High temperatures for industrial processes would be obtained with electricity and hydrogen combustion.

Jacobsen et al. have provided a comprehensive and all inclusive energy alternative for New York State that boasts a sustainable, inexpensive and reliable energy supply that will creates local jobs and save the state billions of dollars in pollution-related costs.

As a small ny green contractor most of these projects are currently too large for us to handle. But the large projects are not the only place to make an impact. Our focus on energy efficient building reduces the need for energy in the first place. Also, micro sustainable energy production such as a photovoltaic installation on a warehouse or home is certainly something we could do. Such decentralized energy sources reduce the load on the grid and in turn create back up options should the central grid go down.

 

Natural Mosquito Control

Summer might not be just around the corner, but once gardens are in full bloom safe insect and pest control will become a necessity. As a NY green contractor that specializes in green roofs and gardens it’s part of our job to ensure that the spaces we create can be enjoyed to their fullest potential.

Mosquitoes and other bugs will exist naturally within any green space and it is important to be able to control their populations. The best option is to use safe and natural methods so as to reduce diseases spread by mosquitoes and maintain a clean and healthy setting. It’s much easier for our clients to enjoy their urban landscape when they are free from worry regarding insects and pests.

With this article we aim to provide a deeper understanding of how one of the most annoying and dangerous pests, mosquitoes, finds a host and the current scientific advancement in safe pesticide production and application.

The focus here is on the mosquito species Aedes Aegypti AKA the Asian Tiger mosquito; most well known for being a royal nuisance but also very importantly responsible for spreading yellow fever. When mosquitoes hunt for a meal they detect a number of chemicals, including carbon dioxide, lactic acid, ammonia, and octenol.

Octenol, in particular, is emitted by all mammals and is a carbon-based compound that has a molecular structure that can take on a “right-handed” or “left-handed” form. Both the right and left forms are a mirror image of the other and the “handedness” of either form determines how its molecular bonds are assembled.

A test performed by Agricultural Research Service (ARS) entomologists concluded that mosquitoes are more likely to be attracted to the right-handed form of octenol emitted by mammals. Information regarding compounds that most attract mosquitoes can be crucial in determining effective pesticide and repellent use.

Traditionally, a variety of man-made chemicals are applied to the body or a garden to repel insects. These chemicals are known to have harsh smells and negative health effects especially when applied directly to the skin. Folk and homeopathic remedies have long been used by indigenous cultures and many are coming under current scientific review.

The USDA and their chief scientific research agency the ARS along with a few collaborators have recently found that the ancient Pacific folk remedy of using breadfruit (Artocarpus altilis) to repel mosquitoes actually holds scientific weight.

Three chemicals within male inflorescences of breadfruit have been identified as being more effective at repelling mosquitoes than the leading repellent known as DEET. These chemicals – Capric, undecanoic and lauric acids (or C10, C11, and C12 saturated fatty acids) – have been recorded as being entirely successful in repelling the malaria carrier.

A separate study that examined the effectiveness of a variety of saturated and unsaturated fatty acids as mosquito repellent found that participants wearing a cloth treated with these compounds were protected against mosquito bites. Dried clusters of the flowers can be burned, as is done in native pacific cultures, to release the chemicals and stave off harmful mosquitoes as well. This is the first scientific research validating the effectiveness of the folk remedy.

In the same respect, ARS scientists studied the effectiveness of the Indian and African method of burning Jatropha curcas seed oil to repel insects. Jatropha curcas is a versatile plant with all parts having homeopathic functions.

In an effort to validate the folk remedy, Natural Products Utilization Research Unit (NPURU) chemist Charles Cantrell extracted the smoke from the plant and analyzed its repellent properties concluding that the free fatty acids and triglycerides present were effective at preventing mosquitoes from biting. Fatty acids have previously been observed to have mosquito repelling properties, but this study is the first to include triglycerides in its findings.

Folk remedies are regarded as safer methods of repelling mosquitoes due to the toxicity of modern pesticides. Chemical pesticides often have a strong negative impact on humans due to the similarity in physiological systems shared by humans and pests.

In further scientific advancement, ARS scientists have tested a new form of mosquito control that they have concluded to be safe for humans, yet detrimental to insect populations. This nonchemical approach involves using a molecular pesticide technology that prevents mosquitoes from producing essential proteins necessary for their survival. The protein present in this pesticide is a nucleic acid such as DNA or RNA that interrupts specific genes within pests.

Due to the gene technology involved, this method can be designed to target a specific pest species and is even effective against species that are resistant to certain chemical pesticides. It is important to use caution with any technological advancement, however this alternative to modern pest control is reported by the USDA to negatively affect only the species towards which the method is directed. This new, nonchemical approach to preventing mosquito bites could serve as a model system for developing new, safer pesticides.

When enjoying your days and evenings in your Brooklyn green roof or garden you probably won’t be using natural pesticides like jatropha curcas seed oil or breadfruit to stave off pesky mosquitoes. But we are looking at these ingredients and many more as possible natural mosquito control. We’ll be sure to keep you posted as our research continues!

Upcycled Shipping Container: Windows

Sustainable architecture and passive building designs are swiftly increasing in popularity and as a NY green contractor we have been busy developing creative and sustainable structures in Brooklyn, NY. Our current project is a two story studio and office space built from 5 recycled shipping containers. A more comprehensive post will be added regarding the entire project, however we are first adding a short series of photographs displaying the process of installing a 9 foot circular window in the second story of the container.

Plastic

Most of us have probably come to recognize that plastic is an extremely difficult item to cut out of our lives. From tupperware to composite lumber, plastic has become so engrained in the modern way of life, most people do not even realize how strong their dependency is upon it. There are ways, however, to curb the impact of our plastic addiction on both the environment and our health.

The EPA’s Resin Identification Code for plastics categorizes plastic into seven numbers. The numbers are useful for consumers who can tell whether a plastic product is recyclable in their neighborhood based on the ID number. For example, #1 and #2 (PET and HDPE) are considered the “most” recyclable and can be broken down into their base form and reworked entirely. Examples of these categories are translucent milk jugs, soda bottles, and plastic bags.

Moreover, the system also shows which types are most harmful to human health. #3 (PVC) and #7 (Other) are considered particularly hazardous to health. The chemicals in plastic have the ability to leach onto food, especially when they are left in the sun or microwave. According to an article in Health magazine, #3 and #7 are often used in “cling-wrap” for meats and cheeses, and plastic baby bottles. Chemical intake can lead to lowered testosterone levels, malformation in children, and cancer. Our advice against this? Buy a refillable metal water bottle and transfer your meats and cheeses to a paper container as fast as possible.

Construction and building is the number two user of plastic products (second only to packaging). According to the EPA, only about 8 percent of plastic waste generated in 2011 was reclaimed for recycling (http://www.reportlinker.com/ci02375/Plastic.html) This is impacted by the fact that most common plastics in construction are rarely recyclable (especially PVC piping). According to a 2000 Green Paper, only 3 percent of PVC is recycled, 17% incinerated, and 80% landfilled. These numbers have improved in recent memory, owing in part to a popular trend in Europe to recycle PVC in window-making (including Eco Brooklyn friend, Klearwall http://ecobrooklyn.com/klearwall-windows-doors/) . One way around this problem is to use PEVA (non-chlorinated vinyl), which is biodegradable and does not contain the hazardous chemicals of PVC.

Exterior Shades – The Anti-Heat Wave of the Future

Temperature has assuredly become a hot topic in offices throughout Brooklyn and Manhattan during the recent heat wave. Eco Brooklyn’s office is no exception to the heat. However, we have a unique approach to the problem.

Passive housing has been a cornerstone of environmental design since the ancient Greeks and Romans (check out this article on the history of passive housing: http://www.planetseed.com/relatedarticle/energy-efficient-building-passive-heating-and-cooling). While technology and techniques have become more advanced, many of the principles used by the ancients have stood the test of time. Most notably, this includes the use of exterior shades to protect from heat in the summer while allowing sunlight in during the winter.

Exterior shades differ from internal shades in a few major ways. Perhaps the biggest difference is that when using internal shades, the sunlight is allowed to enter the room through the window. The heat will be trapped inside of the shades. As it dissipates on the interior, the home is heated much faster.

The second major difference between interior and exterior shades is the dynamic ways one can utilize external shades and shutters. For example, the use of an overhang is an effective way of using angles to shade the windows during the summer when the sun is high. When the sun is lower in the winter, the sun can enter the room under the overhang.

Furthermore, this concept of exterior shading offers an opportunity for synergy – a mark of sustainability in the green building community. Currently, Eco Brooklyn’s offices employ the use of internal honeycomb shades, which are highly effective at absorbing heat. However, we have plans of making an even more effective and synergistic approach. Namely, we would like to install an exterior overhang to accomplish the above-stated goals; with one catch: We will install solar panels on the overhang to absorb the heat and reroute it to power the house. This is a great example of an integrated solar power system.

As global temperatures and sea levels continue to rise across the world (especially in NYC: http://www.huffingtonpost.com/2013/06/10/new-york-city-flooding-by-2050_n_3417348.html), New Yorkers will be expected to assume a heavy burden of increasing energy bills. One way to combat these growing expenses is by building green. Passive housing is a great way to not only take advantage of the Earth’s natural energy, but prevent it from escaping your house as well.

Another approach to natural cooling is to use a green facade, or living wall. This concept involves the use of growing vines and other vegetation in a vertical direction to cover a wall or other surface of a building that is in direct sunlight. Green walls can vary in design and allow room for creativity. For further information on green walls check out this link: http://www.greenscreen.com/direct/GS_AdvancedGreenFacadeDesign.pdf

InsideClimate News – Brooklyn

Eco Brooklyn would like to recognize the efforts and accomplishments of a fellow green advocate located in Brooklyn.

InsideClimate News is a rising nonprofit news website that focuses chiefly on environmental issues. Their objectives include providing scientific and objective investigations and news stories to inform the public and our officials living in these times of serious energy change. Additionally, InsideClimate News attempts to preserve the tradition and utility of environmental journalism.

InsideClimate News covers a wide scope of environmental information. Their hot topics include Keystone XL, natural gas drilling, climate change, nuclear energy, and environmental economics. It is a great site to keep people informed on green topics – from individuals to companies.

Most notably, InsideClimate News won the Pulitzer Prize in National Reporting for its investigative journalism on a 2010 oil spill in Marshall, Michigan. Their ebook, “The Dilbit Disaster: Inside the Biggest Oil Spill You’ve Never Heard Of” is the work of journalists Elizabeth McGowan, Lisa Song, and David Hasemyer. The book’s message details how the spill in Michigan was exacerbated by misinformation, substandard preparation, and a delayed response.

For example, the pipeline that leaked into a local stream, which entered the Kalamazoo River and threatened Lake Michigan, was carrying diluted bitumen. Diluted bitumen, or “dilbit” is a very heavy type of crude oil which is diluted with a cocktail of chemicals. More importantly, no one knew that the pipeline was carrying dilbit and the company, Enbridge Inc., did not inform first responders what they were dealing with until days after the spill was reported.

When all was said and done (though cleanup is still going on at some capacity) at least one million gallons of oil over 36 miles of between the Talmadge Creek and Kalamazoo. These bodies of water were closed for over two years and about 150 families were permanently relocated. The $765 million+ that Enbridge spent on the spill makes it the most expensive in US history. The reason why the spill went virtually unnoticed by the popular media was because the BP Deepwater Horizon spill occurred around the same time.

Enbridge is a Canadian oil and gas company. The dilbit that flowed through the pipelines comes from the tar sands of Alberta, Canada. It is very similar to the type of oil that would be transported by the Keystone XL pipeline.

Klearwall Windows and Doors

Eco Brooklyn was visited today by Klearwall Industries. Klearwall is a certified Passive House windows company. Originally based in Ireland, Klearwall is looking to make its mark in the US market. They offer triple-paned windows and doors for domestic and commercial needs, ranging from single-window installation to entire buildings. Their windows are billed as eco-clad, future-proof, and affordable. All of this is with good reason. 

Klearwall boasts an R-Value as high as 9.8hr.ft².˚F/BTU, which results in a 60% to 74% solar heat gain (depending on single or double glaze). Their PVC frame option is guaranteed to last 35 years and is sold at a bargain of approximately $33 per square foot.

Klearwall’s products are designed, fitted, and tempered in Ireland and shipped to the United States. Their plant is one of the largest carbon neutral factories in Europe and is powered solely by renewable energy. They offer a range of products – from windows in all-wood, aluminum, PVC, or a combination. The PVC and aluminum used is recycled from salvage jobs and treated at the plant.

As a pioneer in passive housing, Eco Brooklyn is always interested in companies such as Klearwall for their business strategy and philosophy. We wish them all the best as they try to help make New York a greener place.

Crown Heights Project – 100% Salvaged Material Fence

Eco Brooklyn has been working on an interesting sustainable project in the Crown Heights area. The challenge is to build a fence using only salvaged material.

How does this project work?

Our green building team collects extraneous wood from the local company, U.S. Fencing Systems, Inc. The staff there are extremely gracious and are happy to see the wood go to good use rather than having to see it lugged off by dump trucks every week. The wood is then transported to the work cite where interns and construction workers de-nail the wooden planks, cut them for sizing, and mount the planks onto the salvaged metal poles extracted from a dumpster near Prospect Park.

This job is a captivating snapshot of what we do as green builders. By reaching out to local businesses and the community, people get excited about sustainability and are more likely to build it forward.

The Real Cost of Cheap Stuff

Bangladesh Building Collapse Kills at Least 70

Texas Fertilizer Explosion Kills at Least 16

Boston Bombing Kills 3

All three of these events happened this week. Most people see the third as very different from the first two. I don’t. To me they are all part of the massive hidden cost of cheap stuff produced by the poor for the over-consumption of wealthy countries.

Next time you buy those $20 jeans or eat the 10 cent banana stop and ask yourself how the hell they can sell them so cheap. I’ll give you a hint: it is not because the business owners are taking less in profits. The answer is they rape whoever they can to get the price as low as possible. This could be people, animals, plants, water, earth, whatever will not fight back in the short term.

And thus we get badly built buildings, slave labor, substandard production, and massive ecological destruction. This is why the overcrowded Bangladesh building collapsed, the understaffed fertilizer plant exploded and the angry, disenfranchised youth lashed out in Boston. It doesn’t take a genius to see the connection. Just don’t look for the answers in the media – big business has too much invested in the current setup to expose it’s ugly side.

This is why when people ask me to compare the cost of green building to normal building I don’t say anything incredibly stupid like, ” Green building is 10% more expensive”.

Normal building is five planets more expensive than green building, which is the amount of planets needed if everyone built like America.

So avoid all that slave labor clothing. ‘You’ got a deal; ‘they’ got dead/poisoned/in-fertile/ enslaved/ abused…fill in the blank.

Its our appetites that are killing us, killing our fellow humans, killing our Earth planet. Our desires and greed.

Earthship Project in New York

We are earthship enthusiasts here at Eco Brooklyn, and are currently speaking with a client who wants to build an earthship in New York State. Here are some ideas being thrown around between Michael Reynolds, Eco Brooklyn, and the client, that we may be able to help turn into reality. The schematic of this global model earthship shows an additional greenhouse that will provide greater temperature stabilization, which would be better suited to New York’s climate, and will provide additional grow space as well. The earthship will of course be capable of functioning independently from the grid. As a Brooklyn Green Contractor, this is a great project that we are excited to be involved with.

Toxic Paint in Brooklyn

Brooklyn is full of beautiful and historic houses, and Eco Brooklyn is doing their part to preserve these wonders through sustainable lead-based paint removal.

Historical Housing

Historical Housing at Ditmas Park

People have been fascinated with lead since the Roman Empire, when tonnes of lead were produced for plumbing, construction pins, makeup, spermicides,  and even lead based tonics and seasoning. Yum!

Even during the reign of the Romans lead was known to have been toxic, but it was not until the 1970’s that it began to be banned among household products. Lead paint was fervently preferred among master painters for its brilliant white luster and its hydrophobic properties.

Research has shown that even mild lead intoxication can have harmful effects, especially among children, and unborn fetuses.

The U.S. Consumer Products Safety Commission banned lead in 1977 from toys, paint, and furniture manufacturing. If your home is older than 1978 you may have lead based paint, and if it was painted earlier than the 1970’s you almost certainly do.

As a Green Contractor, Eco Brooklyn utilizes a safe and non-toxic method of lead paint removal. The first step is to assess the paint with a lead test kit, which can usually be found at your local hardware store.

Lead Paint Remediation Project

We use our own citrus oil based paint stripper (biodegradable), which we cover for a up to 24 hours. The paint can then be easily extracted without dust particulates or hazards within your home. The only intoxication will be from the euphoric citrus scent doing its job, sustainably.  (more…)

The Overview Effect

Here is a short video discussing something called the “Overview Effect”, which is what happens when astronauts first see the planet earth from outer space – a deep sense of awe and connection with the planet. The Overview Effect is not only for astronauts, though. It is for anyone who travels beyond their immediate surroundings and realizes we are all connected with a very precious, beautiful and unique planet.

Whether you do this through actual travel, philosophy, science, religion or drugs, the Overview Effect is crucial to our survival as a race and planet. As a New York green builder and contractor this sense of planetary awe drives us both in our global philosophy and daily activity. It is really what people mean when they say think globally, act locally – the fact that the two are completely connected and the health of one depends on the health of the other.

The Overview Effect

Alternative solutions to lead contamination

Brooklyn prides itself in its historic buildings, but these same sites pose an often unknown toxicity risk to inhabitants. Although the use of lead products was outlawed decades ago – lead-based paints were taken off the market in 1978 and leaded gasoline was banned in 1989 – lead’s legacy continues to taint Brooklyn’ s soils. Lead does not break down or biodegrade but instead it sits there as a bioavailable chemical in the soil, meaning it can be assimilated by plants and animals. As water moves through soil, the lead leaches through soil profiles or lead laden dust is blown, resulting in the lead spreading to nearby lots.

The EPA advises remediation at lead levels of 400 ppm or higher, yet this is substantially higher than advised in many countries, where 100ppm is the average.

In terms of being exposed to lead, no minimum limit has been found at which lead ceases to be toxic. Small children may suffer brain damage, lowered I.Q., slow growth, and behavior problems, while adults may experience muscle pain, nerve disorders, reproductive problems, cognitive decline, and hypertension.

the Eco Brooklyn show house back garden had 2500ppm lead contamination. We remediated it by removing 6" of soil, then digging a hole to access the non-contaminated soil beneath, which we then spread over the rest of the garden. We turned the hole into a natural swimming pool, pictured here.

As a green builder in a lead-contaminated area, one of our primary concerns on a job site is lead containment. In our renovations we find lead everywhere – paint, posts, soil, pipes, railing ends, to name a few.

Molten lead was used to hold iron fences in blue stone like this iron fence at the Eco Brooklyn show house.

Our focus is to achieve our renovation goals while not exposing workers and clients to lead.

 We achieve this through an understanding of how lead spreads and how to contain it. We constantly test for lead, and even when we don’t find any we act as if there is lead and we simply have not found it. For example, we are very careful to contain dust that may seem harmless yet should it contain lead could be devastating to a family, and we never store construction debris in the back yard (a common practice) if we suspect it contains lead since it would leach into the garden soil.

When New York customers come to us with soil remediation projects for their gardens we see lead concentration numbers around 800-4000 ppm. According the Dr Chang at Brooklyn College, where we get our soil tested, this is a very common range in New York.

Our crew remediating a Brooklyn garden.

Traditionally, the primary objective of lead remediation is to remove the lead from the site and move it to an area where people will not come in contact with it. This is the method recommended by Brooklyn College since it removes the lead from the site and is relatively foolproof if correct measures are taken to isolate the house if we are moving soil from the back yard of the brownstone to the front.

Our current service is limited to this method. Although very effective at soil remediation, it is labor intensive and consumes energy due to the need for trucking the soil back and forth.

Because of the drawbacks of typical soil remediation we are researching alternative means of lead remediation in order to improve our services and find more ecological and cost- and labor-efficient solutions.

Another option is phytoremediation, where plants are grown in the lead-contaminated soil, allowed to absorb the lead in their tissue, and then removed from the site. Accumulator plants such as sunflowers and the Brassica family are especially efficient at pulling lead out of the soil. It is very important that these plants are not eaten or used as compost, as this would return lead to the system or contaminate the consumer.

Phytoremediation is good in that it removes the lead from the site, although it does take many seasons for any significant lead reduction to occur. In New York, where every minute is crucial, and where most homeowners are seeking lead remediation because they have young children, waiting several years before playing in their back yard is not a practical option.

A garden where we implemented phitoremediation as part of our soil remediation strategy. We waited until the weed plants had reached maximum height before removing them from the site with the intention that they absorbed some of the lead in the soil.

In the past 15 years scientists have begun to explore the concept of in situ stabilization, or binding the bio-available lead to other compounds in order to limit the concentration of lead in the soil that is actually digestible and therefore toxic to humans. The idea is to treat lead in place instead of simply moving the problem somewhere else. With these methods, lead will still show up on a simple soil test, but it is no longer free to contaminate plant tissue or humans. In essence it is no longer bioavailable or mobile.

Although some scientists are not keen on this approach since it does not remove the problem but merely renders it dormant, it does have some compelling ecological and cost benefits.

In situ stabilization has a couple elements. One is pH control, the other is binding the lead.

Lead is less bioavailable to plants and people in soils with a neutral pH. Soil pH can be controlled by bioremediation. Compost, or organic matter, balances pH levels in the soil while providing essential nutrients for your plants.

The synergistic benefit of adding organic matter like compost to lead tainted soil is that the lead also binds with the organic matter, limiting the amount of total bioavailable lead.

The most efficient form of in situ stabilization involves the use of chemical additions to the soil. Phosphates are a great option since as well as immobilizing lead they also bind with other heavy metals such as copper, zinc, cadmium, and uranium as well.

Eco Brooklyn using calcium phosphate to reduce lead toxicity on a job.

The EPA description for chemical in situ stabilization reads as follows:

Phosphate Immobilization – Using phosphate to bind with the lead, which will allow the metal to pass through the body if it is inadvertently ingested with significantly less harm; combined with

Green Capping – Using compost and green cover such as sod or planter boxes to create a protective layer above the treated soil

The most ideal phosphate source is fish bones. Judith Wright invented the process used to create apatite II, a phosphate mineral apatite particularly efficient at immobilizing lead (patent #6217775). It binds with lead to crystallize as pyromorphite.

She uses crushed Alaskan Pollock fish bones sourced from fisheries and found that when added to contaminated soil caused a 50% reduction in bioavailable lead within the span of a few weeks. Fish bones are free of contaminants and the use of a fishing industry by-product limits the overall contribution to environmental cost. Catfish bones have also been found to be appropriate for the process.

The product was applied in a large-scale project in the heavily contaminated South Prescott community of Oakland, California. Residents were asked to volunteer for remediation, which was handled by the EPA (the area is a superfund site). They were provided with one to two weeks of hotel accommodation for the duration of the work on their yards, as well as landscaping and design assistance post-remediation.

About 3 lbs of fish bones were tilled into each sq ft of contaminated yard, and then covered with 3-6 in of clean soil and plants. Landscapers would then arrive prepared with a series of conceptual yard designs from which to work from in order to restore the inhabitant’s gardens to the most ideal condition. The eco-friendly conceptual designs emphasized native plants, water efficiency, and maximized outdoor use.

Apatite II remediation site in the South Prescott community (Oakland, CA)

The community embraced this method, as it was more cost efficient and environmentally friendly than typical remove and replace soil remediation techniques, while also reducing the disturbance caused by the remediation efforts (removing and carting tones of contaminated soil is not easy).

The traditional dig-and-haul method is estimated to cost $32 per sq ft while remediation via phosphate addition is generally around $18 a sq ft. However, these numbers are EPA estimates, which tend to be less cost-effective.

EcoBrooklyn charges a lot less than EPA estimates for dig-and-haul remediation but it still isn‘t cheap for something that looks the same once the job is done (dirt with lead or without still looks like dirt). The greatest contributor to our cost is labor and the demands of safely bringing toxic soil through a brownstone.

The importance of doing this correctly cannot be understated and we make no apologies for charging more than contractors who see the job as simply removing dirt from a yard. If done incorrectly more harm than good is done because now you have the lead contaminated back yard dust all over the INSIDE of the house. It is no joke.

EcoBrooklyn is very interested in in situ remediation for this reason. Not having to worry about safely moving toxic soil through a home would reduce our costs, so phosphate addition is something we are looking into seriously.

The active ingredient in fish bones is calcium phosphate. While apatite II is the optimal form of the compound for metal remediation, other forms of calcium phosphate have been tested and found to have significant effect on lead bioavailability. Tricalcium phosphate [Ca3(PO4)2]., dibasic calcium phosphate / dicalcium phosphate [CaHPO4], and hydroxy calcium phosphate [Ca10(PO4)6(OH)2] can also react with lead to form pyromorphite [Pb5(PO4)3Cl] and other insoluble lead compounds.

As mentioned before, a simple lead test will not show improvement post phosphate addition since the lead elements are still present. To evaluate the concentration of bioavailable lead, the EPA recommends obtaining an RBA value (relative bioavailability) via an IVBA assay (in vitro lead bioaccessibility). However, it has not yet officially approved the method for the assessment of phosphate amended soils.

A TCLP (toxic characteristic leaching procedure) test determines the mobility of both organic and inorganic analytes. This test would determine how much of the lead in the soil is mobile post phosphate-amendments, although its cost is prohibitive for a New York brownstone back yard soil remediation budget.

A study completed by the U.S. Military on a small arms firing range found that a 5% addition of hydroxyapatite or tricalcium phosphate lowered lead concentrations by 90-95%.

Dibasic calcium phosphate/dicalcium phosphate is a calcium nutritional supplement that can be obtained from some pharmacies and vitamin shops. EcoBrooklyn obtained pure dibasic calcium phosphate powder from Freeda Vitamins. We have been applying it on the recently salvaged lead-contaminated bluestone and soil in the Green Showroom yard.  Since the powder is designed to be ingested as a nutritional supplement, the particles are not toxic to residents.

After boring out the bluestone that contained the lead filled holes around the fence posts we scrub the bluestone with soap then coat it in calcium phosphate.

EcoBrooklyn is also in the process of obtaining apatite II. Although we will probably not stop removing the lead from the site since this undeniably removes the problem from the site, we do see the possibility of removing less soil and adding in situ remediation as part of the process. With these new tools such as phosphate amendments we hope to offer a wider range of lead contaminated soil remediation services to the New York area.

Biomimicry and the Eden Project

The Eden Project

As a New York green builder, Eco Brooklyn is always interested in learning about what other sustainable design ideas are out there.  Last night, I listened to an amazing TED talk that took green building to a whole new level.

Michael Pawlyn, formerly with Grimshaw Architects, London, spoke about biomimicry and sustainable design and how he believes we should be looking to nature for both our inspiration and the solution to our design dilemmas. By looking to nature, we can create more efficient systems and usurp the benefits of nature’s 3.5 billion years of R&D.

Michael Pawlyn also addressed the importance of creating efficient cyclical uses of products (beneficial to both humans and nature) instead of the current, inefficient linear model of produce, use, throw away. (This theory is laid out eloquently in Michael McDonough and Michael Braungart’s must-read, Cradle to Cradle.)

Looking to Nature for Answers

Nature is effecient.  Nature epitomizes the mantra waste not want not.  In nature, waste is food.  Humans, on the other hand, are the polar opposite.  We are wasteful, inefficient, and operate on a use-it-once-and-throw-it-away mentality.

Many engineers and architects are practicing biomimicry, looking to nature for answers to the world’s most pressing problems, including us here at Eco Brooklyn.  The passivhaus pond in the backyard, for example, uses no chemicals, but gravel, rocks, and plants, to filter out dirt and other impurities.  Just like nature would in a pond or lake.

The idea of mimicking nature in manmade inventions is not new by any means.  The Greeks applied “the golden ratio”, also called the golden mean or golden selection, to their art and architecture.  The Pantheon is based on the golden ratio.  Even the volutes on ionic columns use these proportions.

Medieval alchemists would initially determine a plant’s potential healing qualities by what it looked like.  For example, the leaves of the lungwort plant, which resemble the human lung, were used to treat respiratory problems.

Cyclical vs Linear Consumption

Nature functions on a closed loop system.  The waste of one is the food for another.  The dead leaves that come off trees in the Autumn become nutrients for the soil and earthworms on the ground to which they fell.  The earthworms eat the leaves and their waste provide nutrients for the tree, which then gives it energy to produce new leaves in the Spring.

Biomimicry is about creating manmade systems that replicate the remarkably efficient systems found in nature.  In one of his lectures, Pawlyn gives the example of Cardboard to Caviar.  The expensive cardboard packaging that caviar comes in was bought from a restaurant and used as bedding for horses in stables.  When that wore out, it was taken and added to a compost heap that feed worms.  These worms are harvested and sold as food to roe, whose eggs are then harvest and sold as caviar at the same restaurant.  These types of closed looped systems are both economically and environmentally sound.  The metabolism of our cities needs to be reexamined so that nothing is wasted and beneficial, efficient systems are created.

The Eden Project

The eden project biomimicry

Contrary to popular belief, it is possible to create sustainable, carbon neutral (or even carbon positive), green designs that are more efficient and cost less than the “standard” models.  “It is possible to cut carbon emissions and save money,” says Michael Pawlyn. “The key to it is innovation.”  This has been proven by Mr Pawlyn in his work on many projects, specifically the Eden Project in Cornwall, England.

The Eden Project is the world’s largest greenhouse.  It is the second most visited paid attraction in England.  It was designed by Grimshaw Architects and opened in March 2001.

The site is on a reclaimed Kaolinite mine.  Since the site was still being quarried during the design process, they had to design a structure that could be built regardless of the what the final ground levels were going to be.  The result is a series of bubble-like domes of varying sizes strung along the landscape.  By looking to nature, they discovered that the most effective way to create a spherical surface is by using geodesics (hexagons and pentagons).  These bubbles are a series of giant hexagons welded together and then inflated.

The biomes are made of Ethylene Tetrafluoroethylene (ETFE), a transparent polymer that is used instead of glass and plastic in many modern buildings.  ETFE is incredibly strong and much lighter than glass.  Because of the lightness of the material, less steal was use for reinforcement which means more light can enter the space and less energy is required to heat space in the winter.  In fact, the structure itself weighs less than the air it contains

ETFE costs 1/3 less than the traditional glass solution.  ETFE is one percent of the weight of double glazing.

The Eden Project is just one of many examples of biomimicry and how man can learn to be efficient by mimicking what is already happening in nature.  By being aware of how nature solves problems we can improve our everyday lives.  Small things such as composting can make a big difference.  Compost puts nutrients back into the soil, feeds earthworms, and diverts food waste from going to landfills.  Finding new uses for old items gives them a new life.   We saved hundreds of pounds of lovely Blue Stone from a fate of going to the landfill by pulling it out of a dumpster and using it as paving in the front yard.  We can all be eco builders, practicing the principles of biomimicry.

In the words of Margaret Mead, “A small group of thoughtful people could change the world. Indeed, it’s the only thing that ever has.”

Here’s Michael Pawlyn’s TED talk: 

Phone Booth Aquarium

When was the last time you used a pay phone?  For me, I think it was when I was in High School in the early 90s when I was stranded downtown.  But since everyone, and I mean everyone, has a mobile phone now, pay phones are obsolete.   In a way, I am saddened by the fact that phone boxes are useless.  They are cinematic icons (Superman, Charade, and the Birds, just to name a few) and can be found in cities large and small around the world, in various shapes and sizes.

So what happens to all of those phone booths?

 

Sadly, many have already been sent to the landfill.  Others lay unused and neglected on the roadside.  Some, however, are being rescued and converted by very cleaver people into things such as loos and libraries, showers, and sofas.

 

Some of the most exciting phone box conversions have been into fish tanks.  One of my favorites is by designers Benoit Deseille and Benedetto Bufalino as part of the Lyon Light Festival in France.  It is a local curiosity and a big hit amongst visitors.  The Lyon Light Festival is an anual event celebrating the Mother Mary, who, legend has it, spared the town from the Plague in 1643.

Other examples of phone booth aquariums are this goldfish aquarium in Japan:

And this New York-themed fish tank design is from Animal Plant’s “Tanked.”  In doing research for this post I came upon an ad saying that the owners of this aquarium did not like it and put it up for sale on Ebay.

Seeing creative adaptive reuse ideas such as these phone booth aquariums makes me want to go out and adopt an abondoned phone booth.  I wonder if it would fit into a taxi?

Natural Fungus Gnat treatments

As a green builder, EcoBrooklyn is a green wall installer. Recently we designed and installed two green walls in the Area Yoga studio on Montague St. in Brooklyn, one in the entry office and one in the studio itself. The luscious plants beautifully enhance the serene and calming vibe of the space and allow for an escape from the stressors of urban life. The cascading vines and tropical hues transform the studio into a peaceful haven.

Intern Malone Matson tending to the yoga studio's living wall

The system we created uses soil with high organic matter content to nourish the plants. Many of them are of tropical origin and therefore have high nutritional needs. In addition, the studio is hot and humid, a requirement for both the plants and the activity type it was designed for. Our building philosophy embraces low-impact building, and as such we do not use pesticides to keep the plants flourishing. Additionally we allow organic matter to compost on site. The wall is irrigated by a gray water system that keeps the soil generally moist.

While the conditions in the studio are ideal for both the yoga participants and the plants on the green wall, they also provide a welcoming environment for fungus gnats. The gnats feed on organic debris, fungi, algae, and nibble on the small roots of plants.

We have developed a multi-layered plan to keep the gnat population at bay. Much like our plant-based mosquito repellent service, we rely on natural sources of gnat control to diminish the population.

Like our mosquito treatments, we attack all stages of the gnat’s life cycle. Fungus gnats have larval, pupae, and adult stages.

Anti-larval treatments

1) The primary treatment involves the use of cinnamon. We are using a cinnamon spray (cinnamon bark, cinnamon oil, water, and baby shampoo to reduce surface tension) applied twice a day to deter the gnats and create an uninviting environment for them. Cinnamon is a fungicide, reducing the larvae’s food supply.

There are two types of cinnamon: ceylon (cinnamomum verum), and cassia (cinnamomum burmannii). Most cinnamon found in conventional North American stores is cassia, but this form is not a fungicide.

cinnamomum verum on the left and cinnamomum burmannii on the right

2) We are also using Summit mosquito/gnat bits, with the active ingredient bacillus thuringiensis subspecies israelensis. These bacteria are a biological control for larval Dipterans such as mosquitoes and fungus gnats due to the presence of cry toxins. When fungus gnat larvae eat bacillus thuringiensis (Bt) crystals, the cry toxins bind to receptors in the gut and the larvae cease to eat. The gut wall breaks down and the toxin spores and other gut bacteria enter the larvae’s body, which results in death.

The bits are scattered throughout the soil and replenished every two weeks.

Bt does not affect beneficial insects or plants and is a naturally occurring soil bacterium.

According to the EPA, thirty years of widespread Bt use has produced no confirmed reports of immediate or delayed allergic reactions despite significant oral, dermal, and inhalation exposure to the product. Bt has not been found to affect the endocrine or immune systems. Although it does not proliferate in aquatic habitats, it should not be applied to drinking water.

Studies have shown no toxicity or pathogenicity to birds, non-target insects, honeybees, freshwater fish, and estuarine and marine mammals. However, it has been found to be moderately toxic to Daphnia freshwater invertebrates and is under further study. Since our affected site is an indoor planting site, in this particular case we are not concerned about the affect on Daphnia species.

Anti-adult treatments

1) We have applied yellow sticky pads on wire stems hidden within the foliage. The gnats are attracted to the color. We change these out when the surface area of the pad is covered.

2) We have filled jars with apple cider vinegar with a couple drops of baby shampoo or dish soap to break the surface tension. We poke a couple holes in the lids to allow the fungus gnats in but not out. The jars are better for office spaces and bathrooms, and seem to be quite effective.

Additional treatments:

1) ‘Damping off’ is a condition cause by fungi such as Phtophtora and Pythium. The gnats help the fungi proliferate. The fungi infect seedlings and result in a constricted stem and eventual death. The condition can be prevented by the application of chamomile tea. Although this does not attack the gnats themselves, it treats a related condition.

A plant that has experienced 'damping off'

2) Adult fungus gnats like to lay eggs in moist soil. We recommend applying a sand topsoil, which drains quickly and thus prevents the laying of eggs.

3) Sliced raw potatoes placed throughout the affected area attract larva. These can be deposed of and replaced as often as is deemed necessary (they can get pretty infested).

 

We have been treating the green walls for about two weeks now, and have noticed a huge decrease in the fungus gnat population. The workers and customers at the studio have also had positive reports. Not only is the cinnamon spray affective, the aroma of cinnamon pervades the space and complements the character of the studio. EcoBrooklyn will continue to test natural methods of insect control at its job sites.

 

 

Green Roof Professional certification

The Green Roof Professional (GRP) certification system was developed by Green Roofs for Healthy Cities, a not-for-profit industry association working to promote and develop the market for the green roofs throughout North America.

In addition to providing a professional accreditation program, the organization facilitates the exchange of information, supports research, and promotes the establishment of effective public policies. The organization presents Awards of Excellence to celebrate innovative professionals and organizes the annual CitiesAlive conference to develop supportive policies.

Green Roofs for Healthy Cities has been committed to developing a professional accreditation program to legitimize green roof designers and provide education to fill knowledge gaps and improve the quality of work.

In 2004, Green Roofs for Healthy Cities developed its first training course, Green Roof Design 101. It has since added Green Roof Design and Installation 201, Green Roof Waterproofing and Drainage 301, and Green Roof Plants and Growing Media 401. The classes are available in Toronto, New York, Atlanta, and Denver on select dates. They are each full-day courses recommended as a part of the GRP training program. The following half-day courses are also available, and count as continuing education credits:

·  Advanced Green Roof Maintenance

·  Introduction to Rooftop Urban Agriculture

·  Green Walls 101: Systems Overview and Design (2nd Ed.)

·  Integrated Water Management for Buildings and Sites

·  Ecological Green Roof Design

·  Green Infrastructure: Policies, Performance and Projects

·  Green Roof Policy Development

Each course is accompanied by a course manual, which includes all the material on the accreditation exam.

Unfortunately, the accreditation process is rather expensive. Tuition for each full-day course is $399 USD and is accompanied by a course manual. Each course manual can be purchased for $199 USD separately for those who choose not to take the classes in person. The accreditation exam itself consists of 100 multiple-choice questions and lasts 2 hours. It costs $495 USD to enroll and cannot be taken online, but is only offered in Denver, Toronto, New York, and Chicago, incurring further transportation costs. In order to maintain GRP Certification, you must be a Green Roofs for Healthy Cities member ($160 USD annually), and renew your certification every 2 years. This involves completing a minimum of 16 continuing education credits, 8 of which must for GRHC related activities, and paying a renewal fee of $95 USD. Interestingly, each continuing education course is listed at 3.5 units, effectively forcing members to increase the number of classes they must take to maintain their accreditation. Some of the half-day courses can be taken online for $125 USD as part of the Living Architecture Academy.

While the accreditation process may be designed to increase the reliability of green roof designers, Green Roofs for Healthy Cities is also cashing in on the deal. The North American green roof industry grew by 115% in 2011, drawing many more interested professionals and increasing public awareness. Much like LEED in their field, GRHC monopolizes the accreditation process and effectively takes advantage of all the growth.

The existence of the certification is a double-edged sword: while it assures potential consumers that the professional hired has a sound informational backing, it also forces those who want to become green roofers to submit to the monopoly as it becomes the standard.

As a guerrilla green builder, EcoBrooklyn works with clients who seek the most cutting edge techniques. We reduce the net energy of each project by maximizing the use of natural and salvaged materials. The green roof methods taught in the GRP program adhere to the contemporary methodology involving plastics and other foreign materials. While we agree with the basic ideals driving GRHC’s mission (in that the application of green roofs is an essential component to reducing building impact and bettering the urban environment), we do not believe that adhering to the methods prescribed in the accreditation program are necessarily the only right way to build a green roof. In addition, as the organization grows, there is the danger that monetary and political pressures skew the curriculum towards supporting certain brands and materials which may not necessarily be the most ecologically friendly. The GRP curriculum is updated to include new knowledge, and we hope that GRHC’s updates will move towards greater net sustainability.

As it stands, the program is a good way for interested people to learn about green roofs as long as they allow themselves to expand on the ideas taught by GRHC. While we applaud Green Roofs for Healthy Cities’ organizational and promotional achievements, we hope that it does not become a prerequisite to legitimize oneself in the field but instead serves as a possible stepping-stone for professionals.

How to Maintain a Green Roof

how to maintain a green roofAs a green roof installer we have learned that it is crucial to keep in touch with the client for the first couple years to make sure the roof is cared for correctly.

There are some simple tasks that are important to do during the first two seasons so that the roof develops.

Green Roofs, like all gardens, require some amount of maintenance and, like gardens, the type of green roof you have will determine the amount of maintenance it needs.  Intensive green roofs will require much more time and effort than extensive ones.  So as there is no simple answer to the question of “how to maintain a green roof,” here are some general green roof maintenance tips.

 

General Green Roof Maintenance and Care

  1. Weed out unwanted plants. The soil comes with weeds and during the first season it is crucial to remove them to let the still junior plants establish. If you let the weeds run free then the plants we installed will be crowded out and you will be left with a roof full of dead weeks.
  2. Keep the drainage areas clear of plants.  The border around the edge of the roof and the graveled areas around drain outlets and other roof penetrations should be kept clear of all plant life and vegetation.  Plants growing too close to the drain will clog it up, which completely defeats the purpose of having a drain.  Biannual weeding should suffice.
  3. Add compost biannually.  Nutrient-rich compost should be added to the roof garden in spring and autumn.  This provides plants with important nutrients and replenishes the soil.
  4. Weed out unwanted plants (again!).  Being on a roof, seeds dropped by birds or carried by the wind inevitably find their way into your roof garden.  Some of the seedlings are fine and can be left alone.  Others, such as a budding oak tree, are not desirable.  Most likely your roof could never support the weight of an oak, unless your building something like Derry and Toms in London.  Monthly walk-throughs should be scheduled to monitor the types of vegetation growing on your roof.  Unwanted plants, such as the aforementioned oak tree, should be replanted somewhere else, if possible.  Get a group of friends together and do some guerilla gardening with those “unwanted” plants!
  5. Green roofs should be watered as little as possible.  Water is extremely heavy and creates additional weight on the roof.  For lightweight roofs with 4-6 inches of growing medium, desert-type plants are ideal because they require so little water.  Experiment with plant types and, depending on how much rain you get, try to get to the point where you don’t have to water your roof at all.  When it does become necessary to water your plants, err on the side of under watering.  Also, if your roof garden is on a pitched roof, begin watering at the top of the roof to the water can trickle down through the plants at the bottom, which may not need any water at all.
  6. Watch out for pests and diseases.  Keep an eye out for pests and diseases that may come to your roof garden.  While green roofs are designed to attract insects and increase biodiversity, sometimes unwanted insects come along.
  7. Keep a detailed maintenance log/diary.  Schedule when you’re going to do these checkups (and follow through!) and keep and detailed record of your findings.  This will also help you see what plants do best in your roof’s environment.

Natural Mosquito Repellent

Brooklyn’s beautiful summer days coax us outdoors to converse and lounge in our parks, backyards, and porches. In the heat of the summer, water features are a welcome cooling sight and draw the abundance of people looking to maximize their free time. However, these same water features are also home to pesky mosquitoes, diminishing the quality of our outdoor experiences.

At Eco Brooklyn, we are developing natural methods of mosquito control. These methods aim to diminish the mosquito’s presence while maintaining the balance of our fragile local ecosystems. We have a mosquito-repellant service with several components and options, which we make available to the community in an attempt to combat the mosquito problem on a larger scale.

Our service uses three main tools to reduce mosquitoes:

1. Landscaping Mosquito repellent plants – yards, pots and living walls.

2. Water features for mosquito predators – Fish and Dragonfly ponds.

3. Natural oils applied to the skin and garden area surfaces.

New York and Brooklyn were originally full of marshes, rivers and wetlands, which most probably had lots of mosquitoes. The difference now is that those areas are gone, and so are all the creatures and plants that kept mosquitoes at bay.

Now, with little left but clogged gutters and putrid waterways like the Gowanus Canal, there are few predators to the mosquito. Add to that the introduction of non-native mosquitoes from Asia that have even less predators here, and you have a real mosquito heaven (for the mosquito that is. Not for us humans).

Mosquitoes are a problem worldwide.  A wide variety of defenses have been put into effect to reduce the impact of the insect, some with more success than others.

Many of these methods have negative affects on the surrounding environment and may in fact be simultaneously attacking the mosquito’s natural predators. Broad-spectrum insecticides such as the organic pesticide Pyrethrum may kill mosquitoes and other insect pests, but they also kill beneficial pest-controlling insects such as ladybugs and lacewings.

Any attempt to reduce mosquito numbers must be founded in the natural lifecycle of the mosquito itself. The mosquito lays its eggs in standing water and hatches as larva before changing into pupae, then emerging and taking flight. Any standing water greater than a bottle cap’s full can serve as a mosquito-breeding site.

As such it is very important to eliminate small containers that have the potential to fill with rainfall and remain inactive. The elimination of all rainwater collection sites, however, is far from necessary. Slightly larger ponds can be effective methods of mosquito control by acting as habitats for the mosquito’s natural predators.

Some of the mosquito’s natural predators are dragonflies, damselflies, bats, and numerous fish species. While bats do consume mosquitoes, they are at most 5% of their diet. Extensive bat preservation policies, while beneficial to the bat, may not in fact greatly diminish the inhabiting mosquito population. Many fish will consume mosquitoes, but some are better adapted to the task than others.

Fish

The highly touted mosquitofish Gambusia affinis can consume 42-167% of its body weight in mosquitoes per day.  Its mouth is faced upwards towards the sky, allowing for more efficient consumption of mosquito larvae. It can tolerate various temperature changes in the water, salinity, decreased food supply, and organic pollutants and is compatible with goldfish, koi, and karp.

A nonnative species, it was first introduced to New York’s waters as a biological control for mosquitoes. However, mosquitofish were found to be ill-adapted to the cooler waters. Most importantly, it is not compatible with native species and very few instances of coexistence exist.

As such EcoBrooklyn does not recommend the introduction of mosquitofish into existing garden ponds. If your brownstone garden already includes a fish pond, we recommend finding a hardy native fish species that can reproduce in the local climate, such as the fathead minnow.

Dragonflies and Damselflies

Fish are not the only mosquito predator reliant on a pond source. Dragonflies and damselflies lay their eggs in foliage above or below the waterline of a pond. They then hatch as aquatic predators, consuming mosquito larva to feed and grow.

Depending on the species, this stage of life takes 1-2 months to 5 years. The larva then climb out of the pond via a plant stalk or rock and seek protection in nearby foliage before taking flight and attacking mosquito adults.

The life cycle of dragonflies and damselflies therefore shadows that of the mosquito, but the predator-prey relationship remains the same effectively controlling mosquito populations. Adult dragonflies and damselflies return to water features to feed and sun themselves, and eventually lay eggs in the pond.

Eco Brooklyn offers a dragonfly pond building service as a component of its mosquito solutions. Dragonfly ponds are a beautiful addition to a brownstone garden, and the insects provide welcome entertainment on a summer’s eve.

15% of North America’s 307 dragonfly species are in danger of extinction, and a new dragonfly habitat can help the graceful insects to reestablish themselves while also providing a welcome solution to the mosquito problem!

A dragonfly pond by Carole A. Brown

A dragonfly pond should vary in depth, with a segment around 2 ft in depth and flat rocks such as slate on the shallow side. Water plants should be included in the deeper parts of the pond to serve as nurseries, with perching sedges and rushes on the side for adults. It is also recommended that a small wildflower grassland be planted on the side of the pond.

The pond should include erect and submerged plants to allow for dragonflies and damselflies at all stages of the life cycle. A small pump can be included to keep the water clean and oxygenated, although this is not necessary for larger ponds. While the best dragonfly ponds are 20 feet wide, this width is not practical for a NY lot nor is it necessary to maintaining a healthy population.

In fact, adapted whiskey barrels, fountain basins, and earthen or plastic lined ponds can all provide welcome habitats as long as there are sloped sides and varying depths. The dragonfly larvae like to hide in the depths of the water to escape predation, but sufficient plant cover may substitute for that in the case of shallower ponds.

A simple stake in the pond can substitute for erect perching plants. It is very important that the pond be 70% in the sun and that no fish are added to the water.

Fish consume dragonfly larva as well as mosquito larva and are therefore incompatible, unless we design the pond to have two sections so there are safe places for the larvae to escape.

Once the pond is built we jumpstart it with a few spadefulls of soil from a nearby pond with a known dragonfly population.

The following plants work well in a dragonfly pond:

Deepwater -submerged plants

Curly pondweed – Potomogeton crispus

Water Starwort – Callitriche spp

Hornwort – Ceratophyllum demersum

Spiked Water Milfoil – Myrophyllum spicatum

Deeper water Floating Plants

Stiff-leaved Water Crowfoot – Rannunculus circinatus

Frogbit – Hydrocharis morus-ranae

Broad-leaved pondweed – Potomegetum natans

Amphibious Bistort – Polygonum amphibium

Yellow Waterlily – Nurphar lutea

Fringed Waterlily – Nymphoides pelatata

Shallow water emergent plants

Flowering Rush – Butomus umbellatus

Water Horsetail – Equisetum fluviatile

Bur-reed – Sparganium erectum

Water Plantain – Alisma plantago-aquatica

Common Spike Rush – Eleocharis palustris

Bog Bean  – Menyanthes trifoliate

Plants

EcoBrooklyn also installs plants as  a direct means of mosquito control. We offer several plant-based services:

-vertical frames planted with mosquito repellant plants, to be hung on the walls of porches, balconies, and other outdoor activity areas. The frames are made of cedar or pine as both of these woods repel mosquitoes.

-plant troughs filled with mosquito repellant plants, placed near outdoor activity areas

-herbal oil concoctions designed to specifically repel mosquitoes; these can be applied directly to the skin or sprayed on the surfaces of an outdoor activity area

-dried mosquito-repellant plants placed into sachets to be hung in desired locations

Below we have organized known mosquito repellant plants into two categories: native and nonnative species. Edible plants are subcategorized. We work with clients to offer aesthetically pleasing plant combinations.




Once planted, it is advised that plants be brushed before engaging in outdoor activities in order to release some of the scent. The compounds citronellal, geraniol, geranial, and pulegone are all known to repel mosquitoes. Plants containing these compounds are the most effective.

It is important to note that the plants themselves will not repel mosquitoes, it is the oil within their leaves that acts as a repellent. This is why brushing the leaves (resulting in small breaks) helps to repel mosquitoes. Our plant troughs and vertical installations  are meant to be a reliable supplier of leaves for your own herbal concoctions while also aesthetically ameliorating your home.

We highly recommend troughs consisting of edible mosquito repellent plants, which provide the additional ecosystem service of providing food.

Herbal solutions

While there are many variations of mosquito repellant liquids, they are made similarly.

The first method uses actual plant leaves from mosquito repellant plants. These are steeped in water, strained, and then the liquid is added to isopropyl alcohol.  Any combination of plants works well as well as using a single plant per batch.

The second method involves mixing 2 ½ teaspoons of any combination of essential oils (basil, cedarwood, cinnamon, citronella, juniper, lemon, myrrh, palmarosa, pine, rose geranium, rosemary) with 1 cup of 190-proof grain alcohol. These concoctions can be applied directly to the skin or used in a spray bottle. If applied to the skin, it may take some experimentation to determine what combination of oils works best with one’s body chemistry.

As described by the above overview, there are many natural means of combating the mosquito problem in Brooklyn. EcoBrooklyn is constantly improving its services through experimentation in the Green Show House and offers its solutions to the community.

These solutions aim to repel mosquitoes, add to the aesthetic value of Brooklyn brownstones, and support native species and the local ecosystem.

The Art of Shipping Containers

Recently a group approached Eco Brooklyn to help build a cool project involving shipping containers. The project is ambitious: three walls of containers arranged around a central triangular courtyard. The
walls are six levels of shipping containers high totaling 84 shipping containers overall. This is a second attempt to get such a project going. Their first attempt – an eight story shipping container on the Upper East Side – fell through.

As a New York green contractor we really like shipping containers as buildings; they appeal to our affinity for creative reuse and modular construction. Thousands and thousands of shipping containers are sitting stagnant in ports all over the world. In the 1970’s “shipping container architecture” began as trend in design and more recently the already existing building material is moving to the forefront of the sustainable architecture movement. Here are a few examples of architecture which ingeniously utilizes these bountiful, colorful, movable boxes.

Sky is the Limit

Typically when we think of a Japanese tea house, we think of low, thatched roof structures, but with Sky is the Limit, Portuguese artist, Didier Faustino decided to perch this space resting high above the rough sea in Yang Yang, South Korea.

He used two shipping contains to provide a sea-facing observation space atop a tower made out of scaffolding. Visitors must first climb five flights of stairs in order to reach the top of the 65-foot scaffolding.

 

Holiday Cabana at Maduru Oya

Sri Lankan architect, Damith Premathilake was commissioned to design and build a holiday cabana at Maduru Oya.

The lake house sits on an army training camp surrounded by jungles facing a lake as mountains appear in the distance. The structure is made out of materials that were all found on site such as timber from weapons boxes and shipping container.

The project took a total of one month to complete and is total of 700-square feet.

 

OceanScope

Korean designers, Keehyan Ahn & Minsoo Lee have used shipping containers to design a public observatory called Oceanscope. In order to overcome the restraints of the building site, where the ground level is too low to view the sunset across the harbor, the architects utilized old shipping containers to overcome the limitation.

The shipping containers are angled at 10’, 30’ and 50’ to achieve different views. As depicted in the diagram, the observer enters the shipping container and rests ones back against the angled wall, to view the reflection of the sunset through the mirror on the opposite side.

Shipping containers are used for temporary shelter in many rural areas of Korea because of their low cost.

However, indiscreet uses of this recycled product often don’t create harmonious relationships with the natural context because of their industrial aesthetic. Keehan Ahn & Minsoo Lee have been able to take this construction building block and mold it into an innovative prototype for the future of shipping container construction.

Normad Skyscraper

Globalization has given people the ability to not just be citizens of one city or region but become citizens of the world. Luca D’Amico and Luca Telso, two Italian architects submitted this “Nomad Skyscraper” design to a Skyscraper competition in 2011.

The concept centers on using shipping containers that act as individual, personalized apartment units, which can be plugged into the permanent scaffolding.  The main structure would provide basic infrastructure as well as recreational areas.

Units could theoretically be transported by ship, truck and train and transported to other cities, which have this same infrastructure.

Dekalb Market

These shipping container projects are also happening right here in Brooklyn. Take Dekalb Market for example, this low impact, relatively low cost, shopping center has become a centerpiece for the architecture of New York City.

Newark, New Jersey is home to one of the largest ports in North America, there is plethora of these module containers (in a variety of colors!) sitting and waiting to be shipping back to their port of origin. UK developers Urban Splash created a configuration made out of 22 shipping containers occupy a portion of Downtown Brooklyn.

Frietag Flagship Store

One of our readers spent us a link to another incredible example of innovative shipping container design. The Frietag flagship store is composed entirely of rusty, recycled shipping containers that have been gutted, reinforced and configured to serve Frietag, a Swiss company that specialized in products made from recycled materials.

Frietag took its initial objective (creating beautiful products from truck tarpaulins) and pushed it a step further by selling its recycled products within a recycled product.

The building is striking upon first glace, the first two floors are composed of four shipping containers (4×2), and the number of shipping container decreases as the height increases.

This structure is the world’s tallest recycled building, but short enough so that it does not infringe upon the coding laws of Zurich.

 

 

 

 

 

 

 

Biophilia in Brooklyn

As I was walking to the subway after work today, I passed a man who was leaving a few belongings on the sidewalk in front of his house. He is moving to DC tomorrow and, instead of just throwing the stuff away he couldn’t bring with him, he was leaving it out for passerbys to take. There were a few books, some old records, half broken appliances, but the prize giveaway was this massive pot of aloe vera plants.

ny green builder

I quickly grabbed the plant and continued to the subway. As I was riding the J train out to Bushwick, everyone in my car was eying my plant. People were pointing and whispering. When I got off the train and commenced the two block walk to my apartment, I kid you not, everyone on the street stopped to tell me how beautiful my plant was.

A young latino man who was working outside an appliance repair shop stopped me to talk about my plant and asked if he could take one of the baby aloe vera shoots extending from the mother plant. I happily gifted him a young sprout.

I continued walking and was again stopped by a group of Jamaican men who were barbecuing outside their newly opened thrift and clothing store next to my building. They too asked for a shoot, which I gladly relinquished.

Just outside my apartment I was stopped yet again by a young woman. She saw that I had given the two men a sprout and she asked if she could have one too. She didn’t know what kind of plant it was or how to care for it so I taught her a bit about both. She walked away thrilled.

Now the plant, which is still quite sizable, is sitting on my balcony overlooking the J train where commuters can easily look out and see it.

I felt compelled to write about this because I was so impressed by how a green action like donating items instead of throwing them away led to a whole chain reaction of community engagement. It’s incredible that a mere plant can stir up so much intrigue among city dwellers! This especially struck me because earlier in the day I was reading about E. O. Wilson’s Biophilia Hypothesis. Biophilia is a love for living things. The Biophilia Hypothesis suggests that there is an instinctive bond between humans and living systems (i.e. plants and animals). Wilson suggests that as humans were evolving we developed a love for nature because it sustained us and because our love for nature sustained it.

After my experience today, I have no doubt that Wilson was on to something.

DIY Vertical Gardens

Vertical gardens or living walls are a beautiful and efficient way to maximize green space within an urban context. Aesthetically, vertical gardens can be used to improve the façade of buildings while providing other ecosystem services such as enhanced air quality.

Perhaps first employed by the Mesopotamians to create the Hanging Gardens of Babylon, the principles of design have expanded past cascading plants to include plants rooted at different heights of a wall. Living walls vary in size, design, and complexity.

Two of the best-known living walls are on the Marché des Halles in Avignon and the Museé du Quai Branly, both designed by Patrick Blanc. However, man-made living walls are not constrained to grand public buildings.

Marche des Halles en Avignon, designed by Patrick Blanc

It is very feasible to create you own, and in fact personal vertical gardens beautifully complement the exterior of Brooklyn brownstones, although it is recommended a professional be consulted for walls higher than 7 feet.

The character of your vertical garden is determined by the framing material and plant selection. While plant selection may vary by individual taste, native species are generally hardier and better suited to the local climate and pest and disease conditions.

Green landscaping with native species is also a proactive way to support the area’s native ecosystems. You may decide to choose a theme to guide your plant selections, such as a foliage wall, mosquito-repellant wall, epicurean wall (pick your salad ingredients!), aromatic herb wall, or a perfumed wall.

Succulents are easy plants for beginners since they do not need substantial irrigation. For vertical gardens created sans soil, epiphytes and lithophytes are necessary plant selections. Epiphytes attach to other objects solely for physical support and are not parasitic. They obtain nutrients from rain, air, and debris. Common epiphytes in temperate zones such as New York are lichens and mosses.

We will list and describe framing methods with increasing complexity.

The Woolly Packet Garden Company offers a series of “woolly packets”, pouches made from recycled water bottles with an impermeable moisture barrier and felt to wick the water. These packets are easy to install and arrange as you please. Although the design is not constrained to vertical garden use, the pouches lend themselves well to such installations. Watch this video for further description:

Flora Grubb Gardens is featuring an example vertical garden installation in their store.

Wooly Pocket installation

For a more complex system, pre-made frames are available for sale from several manufacturers. Gro-Wall offers easy to stack frames.

VGM also offer green wall modules. Drip irrigation coupled with the effects of gravity water the plants in both systems, although this can also be adapted.

Our favorite option at Eco Brooklyn for small walls is using salvaged pallets as a frame for a living wall. We are currently creating a wooden pallet living wall installation in the Green Showroom. Simple and effective, this method limits the amount of new material needed for the project and decreases life cycle emissions and cost.

Pallet living wall

 

Pallets can often be found for free at local gardening stores. Pallets without significant back support may need to be augmented with scrap wood on the back. You can then staple landscaping paper to the back, bottom, and sides to create a secure void for the soil. Soil is poured through the slats and the selected plants are then planted in place and watered. Once planted, the pallet needs to remain horizontal for one to two weeks until the roots can take and stabilize the soil.

There are two easy ways to create your own frame.

The second method does not require the additions of any soil!

Succulent frames

Method 1: Cut 4 pieces of lumber to the desired length and nail them together at the corners to create a box frame. Staple or nail wire mash to the front face of the frame and a piece of plywood to the back face. Fill the void with soil and then poke the stems from plant cuttings through the mesh. Allow the installation to remain horizontal until the plants are securely rooted. Water lightly or use a drip irrigation system. For smaller frames, it may be easiest to lay it flat when watering and allow the soil to drain before hanging it back up.

Note that the above method works best for small frames, as it does not require a complex irrigation or fertilizer system.

 

Method 2: This last method is the most involved in terms of infrastructure but very rewarding. It isn’t that green either since it requires a pump. It is however the most popular system and many massive walls have been created this way.

Noémie Vialard’s book Gardening Vertically offers a more in-depth description of the process, which was initially developed by Patrick Blanc. While it is possible to make a portable system, it is most effective as a permanent display.

Wooden battens are first fixed to the selected wall space, and then a PVC panel and two layers of irrigation matting are added over the battens. The irrigation system consists of a perforated pipe connected to a pump, which activates a couple times a day for a few minutes.

Nutrients can be diluted into the water tank to fertilize the ecosystem. The plant roots are inserted through holes in the second layer of felt (such that the plant is secured between layers of irrigation matting).

Because the system has no soil substrate, there is no water retention. To mitigate the high water usage, you may want to plant perennials at the foot of the wall to consume surplus water or create a fish pond at the base. Use gray water to irrigate if possible.

Apart from the electric load, this system is not sustainable in another way: if you stop the pump the plants die quickly since there is no humid soil to keep them. In that sense it is a very artificial environment. The closest natural habitat is a rock wall in a tropical jungle.

For this reason we prefer the soil based living walls. We build our own structure instead of buying pre-made products because it allows us to save costs and customize to the space.

A vertical garden installation can beautifully augment the aesthetic value of your home. Living walls do not need to be grandiose or complex and the concept can easily be adapted to personal usage. Outdoor walls are easier because you don’t have to worry about flooring issues in the house. But indoor walls, provided they get sunlight, don’t get blasted by weather extremes. Indoor walls need special attention to avoid mold issues, but if that is under control they add a freshness to the air that is wonderful.

Eco Brooklyn is a living wall installer because we really love what a living wall does to a space. It fits perfectly with our mission to turn NY green!

Bioswale Basics

Do you ever think about where all that water goes when it rains?

In a natural system, most rainwater gets absorbed in the ground where it falls. It gradually flows, or percolates, through the soil until it reaches the water table (the point in which an underground area is saturated with water.) As the water percolates through the soil, it gets filtered of contaminants like pathogens, pollutants, and silt. Gravity slowly pushes the groundwater to a retention area, a place that holds the water like a river, lake, or the ocean.

Managing stormwater

In an urban environment where rainwater falls on impermeable surfaces, surfaces that water cannot pass through like parking lots, the rain becomes runoff which flows over the impermeable surfaces picking up pollutants like lead and then directly into a manmade drain. This water flows through a city’s sewer system where it is eventually treated, which takes a lot of energy and money, and is then released (usually not entirely clean and with harmful chemicals like chlorine that are used to treat the water) into local waterways. During times of flooding, which are becoming more frequent in the Northeast, sewer systems become overwhelmed and cities are forced to release untreated, raw sewage into nearby rivers and oceans.

urban runoff

 

To reduce the damaging effects of flooding and wastewater overflow, urban dwellers should create more permeable surfaces like gardens, specifically ones with bioswales. A bioswale is a low-lying area designed to remove silt and pollution from runoff and to manage flooding.

Many considerations need to be taken when designing a bioswale:

  • Location: must be in a low-lying area where water tends to collect.
  • Gradient: flat areas or areas with a slope greater than 5% are not practical for bioswales.
  • Drainage: use highly permeable mediums like gravel or coarse sands. Do not build a bioswale in an area with a high water table.
  • Plants: choose plants that are both flood and drought resistant. Native plants are better because they do not need fertilizer, will handle the climate more heartily, and will increase biodiversity.
  • Purpose: design your bioswale to solve a specific problem like flooding, high levels of nitrogen/phosphorus, pollution mitigation, or lack of biodiversity.

As an NY green contracting company with landscape design services, Eco Brooklyn can help you design and install a bioswale that will effectively resolve flooding problems, reduce the amount of contaminants entering local waterways, increase groundwater volume, and aid local biodiversity all while adding beauty to your backyard.

backyard flooding brooklyn

This is an example of a bioswale designed specifically to reduce the effects of flooding. It is placed at the lowest point in the yard and is sloped downward to move water to either a drain or retention area. The gravel allows water to enter the ground quickly to stop flooding. We would add more plants to this one if it were ours.

NY green builder

Rain Gardens are a type of bioswale. They tend to have a more aesthetic focus while still redirecting stormwater back into the ground and away from sewer systems.

As part of the city’s plan to retrofit New York, a number of 5 x 20 ft bioswales will be built along city streets.  Read more here.

Eco Brooklyn is planning on building a 5 x 13 ft tree planter that will act partly as a bioswale in the sidewalk outside the Green Show House. We are getting our applications in and revising our design so we hope the project will be underway shortly! More on that as we progress…

 

ADDENDUM: WATER CONTAMINANTS 101

  • Silt: Silt is made up of fine particles of soil, sand, and dust. It is easily transported by runoff because it is so light. When silt enters a waterbody it tends to linger at the surface of the water and eventually settles at the bottom. Not only is the cloudy effect of silt unattractive, but it also blocks sunlight from reaching the aquatic plants inhabiting the water body. Without sunlight those plants will die, diminishing habitat and food sources for aquatic animal life. Aquatic plants also play a major role in adding oxygen to the water. Without them, water bodies can become anaerobic, devoid of oxygen, which makes them inhospitable to plant and animal life and undrinkable for humans.
  • Phosphorus and nitrogen: These are the two elements that drive plant growth. Excess nitrogen (N) and phosphorus (P) enter groundwater mainly from fertilizer that gets washed away as runoff. Large amounts of N and P in waterbodies tend to support large algal blooms. Algae is microscopic and lives at the surface of the water. With enough sunlight, N, and P, blooms can become so large that, like silt, they can block sunlight from entering the water, starving the aquatic plants. When the algae eventually dies, it sinks to the bottom of the water where it will be decomposed, a process that uses up oxygen, thus subtracting further from the water’s oxygen levels. Further, some algal blooms can be toxic, harming the animal life around it, or can be ingested by fish then making them toxic for humans to eat. If you use fertilizer in your yard, consider using plants that have high-phosphorus absorption.
  • Pathogens: A pathogen is a virus, bacteria, or other microorganism that can cause disease. Pathogens are most commonly introduced to water through agricultural runoff of manure and animal wastes.
  • Pharmaceuticals: When we ingest drugs, traces of them are excreted in our urine. These chemicals make their way through the sewer system and into local water bodies. Scientists are not entirely sure how much of an impact pharmaceuticals really have in water systems. It has been suggested that increased levels of estrogen, which come from birth control pills, may be effecting sexual development of some aquatic animals.
  • Heavy metals: Heavy metals enter the hydrosphere mainly through industrial practices like mining and smelting. Heavy metals are dangerous because in large quantities they can be poisonous to humans and animals. If your backyard has a lead problem, for example, use plants that absorb metals. Eco Brooklyn also offers soil remediation services.

The Living Building Challenge- Winner of the 2012 Buckminster-Fuller Challenge

Green building and eco-sensitive design is currently at the forefront of our modern ethos.   What this means for the green builders, contractors and architects of NY, and the world, is a period of dramatic change and challenge is ahead if not already begun. A change in the way we think about new buildings and construction, in how we consider “used” materials and how we use and interact with space.

As Scholar David Orr stated-

“We are coming to an era the likes of which we’ve never seen before, we’re in the white waters of human history. We don’t know what lies ahead. Bucky Fuller’s ideas on design are at the core of any set of solutions that will take us to calmer waters.”

 

One of the most prominent voices in sustainability and responsible design since the 1960’s is R. Buckminster Fuller.  Fuller pioneered in fields from architecture, and mathematics, to engineering and automobile design and only patented 12 designs allowing the vast majority of his work to be open-sourced and free to the public.

His life’s mission and philosophy was simple, “to make the world work for 100% of humanity, in the shortest possible time, through spontaneous cooperation without ecological offense or disadvantage of anyone.”

Even today, years after Fuller’s death his name is still the vanguard of the sustainable design community. The largest testament to his legacy is the R. Buckminster Fuller Institute and their annual international competition the Buckminster Fuller Design Challenge.

According to the institution’s website $100,000 is given “…to support the development and implementation of a strategy that has significant potential to solve humanity’s most pressing problems. Named “Socially-Responsible Design’s Highest Award” by Metropolis Magazine, it attracts bold, visionary, tangible initiatives focused on a well-defined need of critical importance. Winning solutions are regionally specific yet globally applicable and present a truly comprehensive, anticipatory, integrated approach to solving the world’s complex problems.”

In 2012 at an awards ceremony held here in NYC at Cooper Union The International Living Future Institute was awarded first prize for their “Living Building Challenge” initiative.  According to the institute’s website the Living building Challenge is:

-a PHILOSOPHY, ADVOCACY PLATFORM AND CERTIFICATION PROGRAM. Because it defines priorities on both a technical level and as a set of core values, it is engaging the broader building industry in the deep conversations required to truly understand how to solve problems rather than shift them.

-an EVOCATIVE GUIDE. By identifying an ideal and positioning that ideal as the indicator of success, the Challenge inspires project teams to reach decisions based on restorative principles instead of searching for ‘least common denominator’ solutions. This approach brings project teams closer to the objectives we are collectively working to achieve.

-a BEACON. With a goal to increase awareness, it is tackling critical environmental, social and economic problems, such as: the rise of persistent toxic chemicals; climate change; habitat loss; the collapse of domestic manufacturing; global trade imbalances; urban sprawl; and the lack of community distinctiveness.

-a ‘UNIFIED TOOL’. Addressing development at all scales, it can be equally applied to landscape and infrastructure projects; partial renovations and complete building renewals; new building construction; and neighborhood, campus and community design.

-a PERFORMANCE-BASED STANDARD. Decidedly not a checklist of best practices, the Challenge leads teams to embrace regional solutions and respond to a number of variables, including climate factors and cultural characteristics.

-a VISIONARY PATH TO A RESTORATIVE FUTURE

The challenge seeks to encourage designers to bridge the gap between the built environment and the surrounding ecosystems thus reinventing the typical developers’ business model and transforming the role of the building occupant from passive to more of an involved partnership with the earth and her resources.

For all manner of development the Living Building Principles are applicable, whether, “… a single building, a park, a college campus or even a complete neighborhood community, Living Building Challenge provides a framework for design, construction and the symbiotic relationship between people and all aspects of the built environment.”

You can download a complete document that outlines the specific requirements and benchmarks that must be met to receive certification HERE.

With its radical and rigorous requirements, this is more than “green washing”.  This is an excerpt from a statement released by The Fuller Institute after the award ceremony;

“The Living Building Challenge (LBC) is setting the standard for how to build in the 21st century by establishing the highest bar yet for environmental performance and ecological responsibility within the built environment … by “building a new model” and establishing new benchmarks for non-­‐toxic, net-­‐zero structures… The Living Building Challenge goes far beyond current best practices, reframing the relationship between the built and natural environments. LBC seeks to lead the charge toward a holistic standard that could yield an entirely new level of integration between building systems, transportation, technology, natural resources, and community. If widely adopted, this approach would significantly enhance the level of broad-­‐based social collaboration throughout the design and building process and beyond, dramatically reducing the destructiveness of current construction, boost the livability, health, and resilience of communities … the International Future Living Institute is charting a new and critically needed course in an industry that arguably remains one of the most consumptive … The LBC’s model of regenerative design in the built environment could provide a critical leverage point in the roadmap to a sustainable future and is an exemplary trim tab in its potential to catalyze innovation in such a high impact, high consumption industry…”

This is a valuable new asset and tool for the green building and green contracting community in NYC nd abroad in the fight for a greener and livable tomorrow.

Natural Pools

We at EcoBrooklyn engage in a number of exciting green building projects and experiments throughout the year, but with the hot months ahead at the top of our list is the natural pool for the show house and with its completion so close we can almost feel the cool, energetic, life infused water on our toes.

A “Natural pool” is more about incorporating nature into the design and functions of the pool, harnessing natural processes to maintain quality, swimable water and blurring the line between built and naturally occurring.

A healthy body of fresh water has a number of checks and balances that keep it in balance. A Natural Pool simply recreates these elements. Nature does the rest.

A Natural Pool has the swimming area and then another area called the regeneration zone. This zone contains plants and, most importantly, surface area usually in the form of gravel that microbes can live on.

The plants and microbes compete with algae for food and since you pack it with surface area the microbes beat out the algae. In essence you create an environment where food (leaves, soil, bugs, and other organic matter) is scarce, so what food there is becomes eaten by plants and microbes instead of algae.

The process is fairly flexible and can be as simple or complex as you like as long as you have a few basic elements:

-No chemical fertilizers/ pesticides used adjacent to the site

-Natural filtration system

-A variety of different plants, surface area and microbes to promote a balanced ecosystem

The beauty of natural pools

The primary appeal of a natural pool is the absence of the typical cocktail of harsh chemicals designed to kill pretty much everything in the water, except the swimmer more or less.

The second attraction is the positive ecological effect; this is something you can build with salvaged and recycled materials while helping to reinstate local/native ecosystems.

As with most things green there is a degree of time and thought investment not usually associated with the typical energy sapping, chlorinated eyesore.

there’s no competition really

 

Maintenance is still simpler and less expensive, but one needs to learn and follow a set of steps and rules, which as one grows with the pool these steps become second nature, or perhaps first nature…

Thankfully there are always pioneers braving new frontiers and providing the general populace with valuable resources and tools to implement in their own projects.  The Europeans especially have been at the forefront of the natural pools race for over a decade now. They have built massive public natural swimming pools that cater to thousands of people with great success.

wide range of options

Below is a list of websites and organizations specifically geared towards natural pool construction; they provide excellent technical suggestions for all types of designs and constraints as well as helpful trouble shooting for any problems that may arise.  Also they can provide you with competent local green contractors and builders in your area familiar with this sort of construction.

Eco Brooklyn hopes to become a leading natural pool installer in the New York area. We feel this is an excellent option since it adds so much to a garden, both for humans but for native wildlife.

Can Buying Stuff Help Make a Green America?

If you believe in voting with your dollar, then Green America wants to be your ballot box. The organization is like Consumer Reports’ older brother that joined the Peace Corps and goes to protests on the weekends. It evaluates businesses that aspire to sustainable and
ethical perfection with their Green Certification system, posting those they deem exemplary on their National Green Pages website, offering a directory of consciously minded businesses for the concerned customer.

Green America: Come Together

Right now, over me

Green America also engages in activist work in causes that affect consumers. As this includes the vast majority of everyone, their range of campaigns is as broad, spanning from sweatshops to the banking system. In addition, they put on events, including Green Festivals across the country in conjunction with the fair trade certifier Equal Exchange, offering a bazaar of Green Certified businesses along with speakers and workshops, and The Green Business Conference to allow business owners to learn and network.

The company was founded in the 1982 as “Co-op America,” a name jettisoned for its hippie connotations in favor of the trendily ubiquitous yet amorphous “green.” Back in the day, it produced a physical catalog of approved businesses. It was founded on the principle that if people are going to spend money, they should be using it to fight for a vision of a world they believe in.

This is definitely a step in the right direction from blind consumerism, but it should be noted that our major ecological crises are caused by consumption and overuse of resources, and thus a logical solution to the problem should be a massive reduction in our consumption habits.

This would require a change from our current “consumer society” to a “custodian” one- looking after and mending what we already have, repurposing older objects into new forms, and actively caring for our environment. Apart from simply consuming less in the first place it would involve a lot more Cradle to Cradle design where products are designed from the get go to have multiple incarnations.

The core issue with Green America is that despite all the great green companies it showcases, the core message encourages continued consumption. Redirected consumption to “ethical” companies rather than any old corporation is still a push to consume the planet’s resources no matter how green.

Further, the ethics at the heart of “voting with your dollar” are inherently off. It implies you need a dollar to be part of the game. The unequal distribution of wealth leads to an unequal distribution of votes. Who is doing the voting and what interests do they represent? The answers are easy to guess. It isn’t that family in Bangladesh.

Because of this core flaw Green America is not a solution, but a stepping stone, transitional approach, easing our current whacked out economic systems into versions that take into account people and the environment over mere profit. It’s a little like the patch for cigarette smokers – if you didn’t smoke you wouldn’t ever buy the patch but it sure beats cigarettes if you are trying to quit.

In the end, Green America’s message boils down to “keep buying stuff,” not quite a revolutionary concept. If you truly want to make a difference, decreasing, rather than shifting, your consumption patterns is the way to go. But for what you do find necessary to purchase, check out Green America, it may connect you to someone trying to make a difference as they make a living.

Demolished Buildings Get a Second Life as Contemporary Furniture

12×12 is the maximum dimensions a shelter in North Carolina can be before it legally becomes a house, subject to property taxes. For this reason it is a hallowed number among the off-the-grid set, and the title of a popular book on one man’s foray into the world of tiny houses.

A stockbar

This stockbar by Fort Maker was made from 200 year old casks!

It is also the name of a new exhibit of contemporary furniture. New York designers were challenged with creating something beautiful out of the remains of demolished New York City buildings. 12×12 is the innovative result.

The exhibit aimed to draw attention to the potential of materials abandoned to the trash from the many buildings demolished daily in New York. Eco Brooklyn fully supports this goal, as New York’s demolition sites are our preferred resource to build new structures or renovate older ones without requiring any more trees to be felled. In fact, as a New York City green contractor, we have never bought new wood, including all our joists, studs, floors, subfloors, stairs, and doors, with the exception of FSC formaldehyde-free plywood for kitchen cabinets.

By using wood from our very own Gotham Forest, we can help protect living forests by reducing the demand for deforestation, a major driver of climate change and habitat destruction.

Sometimes green design is fun and games: a see-saw by Nikolai Moderbacher

The designers sourced their lumber from landmarks such as the Brooklyn Bridge and Coney Island, as well as buildings from another era and another New York, such as a warehouse from 1832, one of the last of the 19th century’s dry goods district. One of the most glorious aspects of buildings is their ability to serve as witness to countless events and histories, and so the transformations of these storied buildings into furniture allows the sleek, contemporary pieces a depth and richness in their mysteriously alluring backstories.

Some of these stories inform the new pieces, infusing them with a thoughtfulness and humor found in the continuation of a theme, such as a “Vice box” made from the floors of a Prohibition-era dance hall, or a liquor cabinet made with wood sourced from the East Village Mars Bar. You can discover the buildings that became the furniture here.

Perhaps best of all, the unique pieces were sold at silent auction to raise money for Brooklyn Woods, a woodworking training program for low income and high risk New Yorkers, helping to pass on the tools and inspiration to keep New York’s buildings flowing into reincarnations that pay homage to the city’s history while providing for some truly green design.
