Wood Certification

A little while ago we visited a green pavilion with “sustainable” oak floors. We were intrigued by the concept of sustainable oak since oak trees are protected by law and the meaning of sustainable is often skewed by marketers.

After some research we found that there are more than 50 certification systems worldwide, the two largest being the Forest Stewardship Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC). Both are third-party certifiers in that they are independent and non-governmental.

In North America, the three additional certification systems endorsed by the PEFC are the American Tree Farm System (ATFS), the Canadian Standards Association’s Sustainable Forest Management Standard, and the Sustainable Forestry Initiative (SFI) Program. Currently only 10% of the forests in the world have been certified as sustainable.

The Forest Stewardship Council was the first established third-party certification system and many others followed suit. There is criticism that the abundance of certification systems results in consumer confusion in relation to standards, therefore allowing some systems to uphold laxer standards.

LEED only accepts certification systems that adhere to the USGBC Forest Certification Systems Benchmark. A draft is available here.

Currently only Forest Stewardship Council – certified wood is eligible for LEED points. FSC accredits its associated certification bodies and checks compliance through audits.

The FSC has 10 general principles for responsible forest management:

Principle 1: Compliance with laws and FSC Principles – to comply with all laws, regulations, treaties, conventions and agreements, together with all FSC Principles and Criteria.

Principle 2: Tenure and use rights and responsibilities – to define, document and legally establish long-term tenure and use rights.

Principle 3: Indigenous peoples’ rights – to identify and uphold indigenous peoples’ rights of ownership and use of land and resources.

Principle 4: Community relations and worker’s rights – to maintain or enhance forest workers’ and local communities’ social and economic well-being.

Principle 5: Benefits from the forest – to maintain or enhance long term economic, social and environmental benefits from the forest.

Principle 6: Environmental impact – to maintain or restore the ecosystem, its biodiversity, resources and landscapes.

Principle 7: Management plan – to have a management plan, implemented, monitored and documented.

Principle 8: Monitoring and assessment – to demonstrate progress towards management objectives.

Principle 9: Maintenance of high conservation value forests – to maintain or enhance the attributes which define such forests.

Principle 10: Plantations – to plan and manage plantations in accordance with FSC Principles and Criteria.

The FSC certification promotes forests that are exemplary of ecologically, economically, and socially sustainable management practices. Sustainability has been defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs, so the certification ensures that forest managers ensure the long-term health of the forest in question.

FSC also provides chain-of-custody certification, which takes into account all companies that have touched the lumber before it is purchased by a consumer.

The detailed standards can be found at www.fsc.org.

The certification systems promote responsible building practices by allowing builders to work with sustainable materials. At EcoBrooklyn, we try to work mostly with materials salvaged from dumpsters, which is the most sustainable option available. It is rare we buy new wood any given year.

Certified woods offer an acceptable last option alternative. But as a green building company we are skeptical of certifications. Most of them are simply labels that allow the consumer to feel better about their purchase and allow the producer to sell more, but in reality not much has changed. Trees are cut down, habitats are destroyed.

It is impossible to reproduce that. Even when companies replant trees, they do it as a mono-culture with one species of tree. That is like saying elevator muzak and Mozart are the same. One is lifeless. The other is full of life.

Understandably our view is not main stream. If it were then most construction would come to a screeching halt and we would love that. But realistically certifications are a move in the right direction for mainstream builders. With time hopefully the certifications will get more and more stringent.

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?

Global Drug Routes. Hmmm...who's the biggest drug addict?

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.

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.

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.

 

DIY Rocket Mass Heater

The recent polar vortex has hit us all with some really harsh conditions and as a green contractor based in New York it has made work on our ecological construction sites difficult. Spending cold, winter days inside of an upcycled shipping container can leave you freezing for hours. Space heaters require electricity that you may not have access to.

We’ve figured out a way to heat our workspaces in an environmentally friendly and sustainable way that uses zero electricity and burns zero fossil fuels.  A rocket mass heater is an efficient wood burning stove and space-heating system. Two key things differentiate them as ecologically sound space heaters.

The first is that the design involved creates a small, efficient, high temperature combustion chamber capable of burning significantly more carbon than simply burning wood in a metal can or bonfire. Due to the high carbon-burning capabilities less ash is created and the smoke emitted is much cleaner.

The second is that the cob or clay acts as a thermal mass that physically stores the heat created during combustion for hours and releases it into the space through convection thereby decreasing the amount of electrical energy or fossil fuels used.

A traditional rocket mass heater involves a 55 Gallon drum built into a clay wall and extending into a room so as to transfer the most heat possible. This form is too large and too permanent for use on multiple construction sites.  The technical design of a larger scale heater is more complex, but we needed a relatively small heater that can be transported between sites.

The method of building a rocket mass heater outlined below enables environmentally conscious contractors and individuals to use materials that are more readily available or perhaps lying around the house or job site.

Here we’ve provided the simple DIY steps to creating a rocket stove or rocket mass heater:

Materials:

5-gallon plastic bucket

2 2-liter plastic soda bottles

Dirt, grass (or hay), and water

Marker

Duct tape

Utility knife

A piece of metal lath or mesh

 

Step 1: Use the marker to trace a circle 3-4 inches from the bottom of the 5-gallon bucket and cut out the circle with your knife.

Step 2: Use the duct tape to tape the ends of the soda bottles together in an L shape. The soda bottles should be filled with liquid or remain unopened.

Step 3: Use the dirt, grass (or hay), and water to make the cob in a different bucket.

Step 4: Put some of the cob in the bottom of the bucket to the height of the bottom of the hole you’ve cut. Place the bottles you’ve taped together inside the bucket with the end of one bottle sticking out of the hole that you’ve previously cut.

Step 5: Continue to fill the bucket with the cob mixture and be sure to smooth all edges. The clay will need a few days to dry out.

Step 6: When the cob feels dry pour the liquid out of the soda bottles and cut off the tops of the bottles. Remove the bottles and tape by reaching into the bottles and pulling them out.

Step 7: If your cob mixture is not fully dry let it set for a few more days. Then place paper and small twigs inside and light a small fire to dry the cob entirely.

Step 8: Place the piece of metal lath or mesh, small enough to fit inside of the hole, in the side of the bucket. This will hold the fuel being used to heat your space. It should be long enough that it sticks out of the bucket to hold longer sticks/kindling.

Step 9: Add your fuel (paper, sticks, any natural carbon-based material will do) and ignite!

This rocket mass heater is safe, environmentally friendly, and portable. For use indoors this structure would need to be ducted to allow exhaust or fumes to be safely expelled outside. Additionally, use of this type of heater in a home remodel is not recommended however for work on an industrial space it is a perfect fit.

Click HERE for a link to a smaller, even more portable version.  We don’t recommend this exact method due to the high levels of BPA inside of soup cans so we suggest purchasing heater duct pipe (un-galvanized) to use instead.

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

Eco Brooklyn’s latest project was developed for our client in Williamsburg. The client was looking to renovate their distressed backyard and create a beautiful space to sit and relax. We first develop a design and render it for the clients approval. This deck is perfect for small gatherings, allows access to the yard, and the large stairs double as sitting space.

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.

Klearwall PH Windows

energy-saving-windows-doors

As New York passive house builders, Eco Brooklyn gets approached by many distributors offering Passive House   products. Recently Klearwall, a PH window company located in Ireland, informed us of their intended expansion in New York City. Klearwater offers thermal bridging calculations, which shows how much energy will be conserved by the instillation of their triple pane windows. The windows are PH certified and manufactured in a plant powered by renewable energy.  The plant is carbon neutral and harnesses its energy from two on site wind turbines and a co-gen plant.

Air Sealing in Brooklyn

Eco Brooklyn was recently commissioned to insulate a new development in the Brooklyn neighborhood of Bedford-Stuyvesant. As a specialist in insulation and air sealing we have seen an increase in business from the many new multi unit apartment buildings that have shot up – not during construction, but AFTER construction.
As housing demand has continued to rise in New York City, developers have been driven to build quick, and build cheap. In this process, the basic concept of insulation is bypassed in favor of a quickly constructed shell of a building to show potential residents the physical product, but all too late, residents come to realize that they end up paying enormous utility bills because the units they live in are exactly that – a shell.

A brand new development….
 Insulation contractor
As a Green Builder, energy conservation is an important focus for us. Not only do residents personally benefit from the energy savings (40% of energy costs are due to air infiltration that proper insulation will greatly reduce) and a comfortable sound and temperature controlled home climate, but they put less strain on the energy grid as a whole, which has far-reaching effects for the country and the world.
More importantly, the idea of conservation, to use only what is necessary rather than gratuitously simply because we are fortunate enough to be able to, is a multi-layered concept that is all too easy to forget when one lives in a developed country such as our own. The DOE’s Building Energy Codes Program (BECP) provides a guide for national energy codes.

The two basic forms of insulation that Eco Brooklyn used are Cel-Pak, a loose cellulose spray, and spray foam.
Cellulose is a green alternative to fiberglass largely because of its mostly recycled content of roughly 85% shredded newsprint that has been chemically treated to resist mold, fire, and pests, without the use of formaldehyde, asbestos, and glass fibers. According to the Cellulose Insulation Manufacturers Association (CIMA), “In 2007 about 3,000,000 tons of newspapers went to U.S. landfills.  This paper could have been used to produce an additional 200,000,000 bags of Cellulose Insulation.  There is enough paper going to landfills to produce enough Cellulose Insulation to replace nearly all other types of insulation.” The manufacture of cellulose as well requires significantly less BTU to produce that standard fiberglass.
A large benefit of loose cellulose spray is the ability to conform around plumbing, wiring, outlets, and vents, allowing for a custom fit uniform thermal barrier for every cavity. It has an R-value of 3.8 per inch, allowing exterior wall designs to reach a higher total R-value. Though this is not the highest, its cost per R-value is low enough to make it a sound investment.
Holes are drillled into the tops of walls and the spray cellulose is blown in until the capacity is reached. There is a tendency for the material to settle up to 20%, therefore requiring that the application be continued after some settling time. In this case, Eco Brooklyn used this method to insulate the exterior walls of the building.

Closed-cell spray polyurethane foam (SPF) is a cheap form of permanent flood resistant insulation that is easily available. SPF has an R-value of 6.0 per inch, which is greatly superior to that of cellulose. However, the environmental impact from its manufacturing is far greater and the adverse health effects caused by its chemical makeup have been brought up by the EPA, and therefore minimal use is preferred. Eco Brooklyn used SPF in the exterior walls and behind the baseboards of the building where moisture has a greater tendency to collect, It’s waterproofing feature is best used here to prevent mold growth. Rockwool is used as a filler to reduce the amount of foam needed, and the openings are covered with cut foam board. Tescon tape provides an airtight, waterproofed seal.

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.

Permaculture Tour this Sunday 03/10/13 @ 11:30 am

Eco Brooklyn will be hosting a Permaculture tour of at least 30 people this Sunday. It is open to all who are interested in touring the Eco Brooklyn Show House and learning about permaculture.

Location: 22 2nd Street Brooklyn, NY 11231

Time: 03/10/2013 @ 11:30

No RSVP required, just show up.

Permawhat?

Permaculture is a synergy between land use, agriculture, and human development. Coined by the environmentalist-authors Bill Mollison and David Holmgren from the phrase “Permanent Agriculture.” Permaculture evolved into a social awareness philosophy that focuses on a healthy planet in which to sustain a human population. It thrives on understanding the natural processes of biology to sustainably integrate farming, aquaculture, and land development. Permaculture advances the organic efficiency of pre-industrial farming  and places more value on renewable resources and limiting waste production.

Major concepts of this philosophy include: Food Forests and Guilds, Poultry and Backyard Animals, Rainwater Harvesting, Polyculture and Multipurposing, Watershed Restoration, Natural Building, and Waste Management.

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.

Sustainable Paint Removal

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…)

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.

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.

Leave Your Surroundings Cleaner Than When You Arrived

When I first started mentoring interns one of the first things I told them was that they always had to leave their work area cleaner than when they came to it. Over time this metaphor became the most powerful thing I think I can teach them.

Leave your surroundings cleaner than when you arrived…..

If that isn’t the most beautiful mantra to live by I don’t know what is. And unless it isn’t painfully obvious, by “cleaner” I don’t mean organized or disinfected. I mean leave nothing behind but footprints in the sand.

And because of the laws of entropy this does not mean simply not making a mess. By merely living you make a mess. Even the most austere yogi consumes, kills other creatures, and creates waste. So if you really want to leave the world cleaner than when you arrived you have to actively clean up.

And you can’t just clean up after yourself. Because the world is global and most of your mess is actually being made by a manufacturer across the planet, it isn’t enough to simply keep your own life clean. You have to proactively clean up after others if you want to even make a dent in the mess your life creates around the world.

As a New York green builder I am blessed by an occupation where I spend my days cleaning up after other people. So this mantra is easy for me. We are constantly salvaging other peoples’ garbage and creating beautiful eco homes out of it. I can think of nothing more satisfying than knowing each day I have made the world a better place. I am very grateful.

Here is a great clip on this topic that shows how you can create friendship, a sense of connection, a sense of purpose and a sense of fulfillment by simply picking up garbage. It is a powerful and simple message, and one that I plan on doing with my interns. We are going to the Gowanus Canal, which happens to be a block from the Eco Brooklyn Green Show House, with a bunch of garbage bags and a six pack of good beer to leave it cleaner than when we arrived.

Das Haus: First NYC Passive House in BK

For those of us who live in historic homes we know that our period dwellings bring us both joy and frustration. The frustration is largely attributed to the endless repairs that classic Brooklyn Brownstones require and their not so efficient envelope.

Eco Brooklyn has renovated many brownstones and knows first hand how challenging it can be to air seal and insulate an building while still keeping it’s traditional character.

With the advent of new energy efficient building techniques Eco Brooklyn is part of a new trend in Brownstone renovation: instead of following traditional guidelines to fixing up a house, some Brooklyn homeowners are transforming their townhouse into a Passive House – a German technique that can reduce a homes energy consumption up to 90%.

This past week, the Eco Brooklyn interns took the metro North train up to White Plains for the Das Haus Symposium. There were a number of speakers, some coming all the way from Germany to talk about projects, ideas and products that have either already migrated to the US or are on their way. The Passive House concept was a topic of interest.

The Passive House standard focuses on 5 main strategies:

  1. Insulate strategically
  2. Stop Thermal Bridging
  3. Achieve air tightness
  4. Install high-performing windows for thermal comfort
  5. Reduce mechanical systems with heat recovery ventilation

Jordan Goldman, the engineering principal at Zero Energy Design was a speaker at last week’s symposium. He is a Passive house consultant who recently finished a passive house restoration at 23 Park Place in Park Slope. The completion of this project marked the first certified Passive House in New York City!

The original structure at 23 Park Place was built in 1899 and had been owned by a few artists until it was abandoned a few years ago. After the new owners purchased the dilapidated property they decided to do a Passive House retrofit on the existing structure. Julie Torres Moskovitz from Fabrica718 was the lead architect on the project. She enlisted Jordan Goldman as the engineering consultant on the design.

Since this property was not land marked the retrofit became a complete makeover for the structure. For instance, all the fireplaces and chimneys were replaced to increase the overall air tightness of the space.

As noted before, air tightness and a system of interior and exterior air exchange are the key stone elements to creating  a cohesive thermal envelope ensuring maximum energy reduction.

23 Park Place met the air tightness requirements of a passive house, and far surpassed the requirements of NYC. 23 Park Place is not only 15 times tighter than a current building norm is achieved the highest air tightness level in all of New York City-  .38!

In addition to the insulation, comprised on 23 inch thick walls and three pane windows

Passive House calls for all the joists and meeting points to be sealed to create a continuous thermal envelope.

Although after so much emphasis on the insulation, you must be wondering how could anyone possible endure such stuffy conditions. The answer to this seemingly uncomfortable air is the energy recovery ventilator or E.R.V.

Essentially, the inside air is pulled through the ventilator, the heat is then transferred to a membrane, the air is cooled and then exits as exhaust. The fresh air outside is simultaneously being pulled in and warmed by the membrane. This system, which is referred to as “counterflow” maintains a constant temperate within the thermal envelop.

The Passive House energy use standards are far more stringent then those used by the US Green Building council, which issue certifications for LEED and the Energy Star program. It is considered excellent if a LEED certified structure can reduce energy consumption by 30% and Energy Star homes typically save about 15 to 20%.  With a Passive House there can be up to a 90% reduction in heating and cooling.

Now that’s a paradigm!

Fortunately there are a number of Passive House projects underway in New York City, many of which are located right in Brooklyn. As a New York Passive House builder we hope to see an increase in the demand for Passive House design in the upcoming years. It costs within the range of normal construction yet greatly decreases a building’s impact on the environment.

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:

This aquarium, which was part of an entire exhibit featuring creative fish tank ideas:

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?

Sustainable Wood

Last Tuesday the EcoBrooklyn interns attended the dasHAUS symposium and tour in White Plains, New York. The touring exhibition features the mobile dasHAUS pavilion, constructed of fully functioning sustainable energy technologies. The pavilion’s design is inspired by the Technical University of Darmstadt’s winning Solar Decathlon entries in 2007 and 2009. The tour, organized by the German American Chamber of Commerce, is meant to engage and educate the community while also connecting industry professionals. After a series of lectures by various professionals in related fields, the attendees were guided through the pavilion and introduced to the unique elements of the design.

The docent mentioned that every piece of the pavilion is German aside from the “sustainable” oak floors. We were intrigued by the concept of sustainable oak since oak trees are protected by law and the meaning of sustainable is often skewed by marketers.  Upon further questioning the docent shared that oak is a particularly good insulator wood, but that he was unsure of what sustainable wood entailed.

After some research we found that there are more than 50 certification systems worldwide, the two largest being the Forest Stewardship Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC). Both are third-party certifiers in that they are independent and non-governmental. In North America, the three additional certification systems endorsed by the PEFC are the American Tree Farm System (ATFS), the Canadian Standards Association’s Sustainable Forest Management Standard, and the Sustainable Forestry Initiative (SFI) Program. Currently only 10% of the forests in the world have been certified as sustainable.

The Forest Stewardship Council was the first established third-party certification system and many others followed suit. There is criticism that the abundance of certification systems results in consumer confusion in relation to standards, therefore allowing some systems to uphold laxer standards.

LEED only accepts certification systems that adhere to the USGBC Forest Certification Systems Benchmark. A draft is available here: https://www.usgbc.org/ShowFile.aspx?DocumentID=6225

Currently only Forest Stewardship Council – certified wood is eligible for LEED points. FSC accredits its associated certification bodies and checks compliance through audits.

The FSC has 10 general principles for responsible forest management:

Principle 1: Compliance with laws and FSC Principles – to comply with all laws, regulations, treaties, conventions and agreements, together with all FSC Principles and Criteria.
Principle 2: Tenure and use rights and responsibilities – to define, document and legally establish long-term tenure and use rights.
Principle 3: Indigenous peoples’ rights – to identify and uphold indigenous peoples’ rights of ownership and use of land and resources.
Principle 4: Community relations and worker’s rights – to maintain or enhance forest workers’ and local communities’ social and economic well-being.
Principle 5: Benefits from the forest – to maintain or enhance long term economic, social and environmental benefits from the forest.

Principle 6: Environmental impact – to maintain or restore the ecosystem, its biodiversity, resources and landscapes.

Principle 7: Management plan – to have a management plan, implemented, monitored and documented.

Principle 8: Monitoring and assessment – to demonstrate progress towards management objectives.

Principle 9: Maintenance of high conservation value forests – to maintain or enhance the attributes which define such forests.

Principle 10: Plantations – to plan and manage plantations in accordance with FSC Principles and Criteria.

The FSC certification promotes forests that are exemplary of ecologically, economically, and socially sustainable management practices. Sustainability has been defined as development that meets the needs of the present without compromising the ability of future generations to meet their own needs, so the certification ensures that forest managers ensure the long-term health of the forest in question.

FSC also provides chain-of-custody certification, which takes into account all companies that have touched the lumber before it is purchased by a consumer.

The detailed standards can be found at www.fsc.org.

The certification systems promote responsible building practices by allowing builders to work with sustainable materials.  At EcoBrooklyn, we try to work mostly with salvaged materials, which is the most sustainable option available. Certified woods offer an acceptable alternative. We urge builders and contractors to consider purchasing certified woods for their projects.

 

Is New York the Next Venice?

Sea level rise on the East Coast  is accelerating at a rate much faster compared to the rest of the world. After analyzing tide levels data from North America, scientists have unexpectedly found that there is a 1,000 km-long sea-level rise (SLR) hotspot on the highly populated Eastern coast of North America.

 

The hot spot stretches from Cape Hatteras, North Carolina, to the Boston area and continues to climb by about 2 to 3.8 millimeters a years- roughly 3-4 times higher than the global average.

Contrary to popular belief the global sea level is not rising at a consistent rate. The variations are the result of dynamic processes, which arise from circulation and variations in temperature and salinity, disruptions in Earth’s changing gravity, rotation and shape.

Sea levels are expected to rise as global warming continues to intensify, melting polar ice caps. As global temperatures continue to rise, the ocean absorbs the majority of the heat, resulting in the expansion of oceanic water.

Over 141,000 New York citizens are currently living within three feet of high tide- the same amount of sea level that will rise by 2100. It has also been reported that land 3.3 feet below sea level will one day be permanently underwater, this could occur within 100 years.

It is the potential of storms that should really have New Yorkers worried. The NY metro area hosts the nations highest density population that is vulnerable to the sea level rise.

It doesn’t help that the NY harbor is a funnel shade that would only help to magnify a storm surge.

Our homes and infrastructure are often built to withstand a “hundred-year storm”- a storm with such magnitude that there is a one percent chance it would occur in any given year. But what will happen to our built environment when 100-year storms begin to occur every 10 year and a 10-year storm is a regular event? We as green contractors need to start looking into the quality and longevity of our buildings today in order to better prepare clients and ourselves for the future.

In addition to strengthening our structures we may need to reassess where we are building.

As the likelihood of flooding and storm surges increases, we are beginning to be forced to reevaluate where we live. Much of New York City is just 16 feet above the mean sea level; some parts of Manhattan are only five feet above sea level! Some scientists are suggesting a drastic approach to future development of New York City: move the majority of people to high-lying areas and leaving the low-lying area as parks and buffer zones.

But there is hope! New York is among the best prepared cities in the country.

Last year, Mayor Michael Bloomberg announced that he was donated 50 million to The Sierra Club, the nations largest environmental ground for their “Beyond Coal” campaign. Their campaign aims to halt the opening of coal plants which are responsible for about 20% of global carbon emissions.

“Planning for climate change today is less expensive than rebuilding an entire network after a catastrophe,” said Mayor Bloomberg in a release in 2009.

It seems that the definition of “sustainable” is a continuously changing; building for the future not only means creating a build environment with longevity but building an environment that can withstand the power of nature.

Here is a link which shoes how your area will be affected my rising sea levels.

 

 

 

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.

I am A Weed (part 2)

This blog post is in response to my post last week, “I Am a Weed.

NY green build-design

Since a lot of Eco Brooklyn’s work involves creating ecological plant-scapes, the issue of weeds and native species arrises a lot. As an ecological landscaper we’ve learned that the only difference between a weed and a plant lies in the definition of the beholder. For example we plant a lot of native grasses, considered your archetypal weed to the typical green lawn installer. In general we tend to plant in a much more “wild way” than your typical landscape design.

We also plant in a lot more places than considered normal in a city – on roofs, walls, stairs and any other surface. By doing this we are aware that our work spreads a lot of native plants throughout the city through wind and bird droppings.

If cities were to increase their leniency toward spontaneous urban plants, how could they do so responsibly? There are some valid points to be made in the argument against weeds. Some plants, such as ragweed, cause allergic reactions. Others have the ability to completely dominate a landscape and kill off any other competing plants, like japanese knotweed. In a few rare cases, exotic spontaneous plants have brought in diseases or funguses that affect native plants. Dutch Elm Disease, which was actually introduced by an insect, not a plant, is the most infamous of these. It’s an impressive feat for a plant to survive in the crack of a building, but if it grows so large that it jeopardizes the building’s infrastructure then that is a problem. So where should these plants be grown and how?

A passive answer to this question are brownfields. Brownfields are abandoned or underused patches of land that once facilitated industrial or commercial activity. These unattended sites can quickly become inhabited by spontaneous plants and given free reign, soon grow into little forests, discreetly nestled within a city block. In these scenarios, an unsightly vacant lot morphs into a green field with zero human effort or money put into it.

 brooklyn contractor

A more proactive way of including spontaneous plants in our urban environments is via brown roofs. Brown roofs are very similar to green roofs. They share many of the same construction methods and benefits. The difference is that the dominant aim of a brown roof is to increase biodiversity, whereas green roofs tend to focus more on aesthetics. A green roof requires a certain amount of tending whereas a brown roof is purposely left undisturbed so that local wildlife can colonize it. In this unmanaged state, brown roofs offer hospitable land for the airborne seeds of spontaneous urban plants.

urban landscaping

A brown roof can be seeded when it is first created or it can be designed to set up the proper conditions (i.e. a plantable substrate) for plant life to grow and then left to the forces of nature. In the latter scenario, it takes about two years for the brown roof to fully grow in. Although somewhat popular in Europe, because of the slow rate of return and lack of control over the roof garden’s aesthetic, brown roofs are very rare in the US. I think it is understandable to prefer a green roof on one’s home or in a public area, but I propose that large buildings like factories looking to cut down on energy costs consider building brown roofs as they will help insulate the building while requiring very little maintenance.

ny green roof builder

Sometimes piles of logs or stones are added to brown roofs to further promote biodiversity

To clarify, although brown roofs can largely be left to themselves, they don’t and shouldn’t be left entirely untouched. Undesirable plants, such as those that cause allergies or are aesthetically unappealing, can be removed. Invasive plants should be pruned or taken out. What it comes down to is reconsidering “gardening” altogether, not just the plants being used. Recall land artist, Michael Heizer’s, work Double Negative (see “The Earth Art Movement”). Heizer makes us question whether something is art if it is created purely by subtraction. With a green roof or any other garden, we choose the plants and place them where we like– addition. However, a brown roof that is left to colonize itself can be developed simply by taking away plants– subtraction. Subtraction, in this case, is the less energy intensive option. It is working within nature instead of outside it.

In the book Eaarth, Bill McKibben suggests that global climate change has reached the point where it is no longer preventable. It is happening and there are going to be dramatic changes to our world. McKibben says we can either keep wasting our time trying to stop the unstoppable or we can accept the reality of our situation and prepare for a new way of life. To a lesser extreme, I believe the debate about spontaneous urban plants is a similar one. Perhaps it is time to realize that eradication is impossible and to start working with them instead of against them.

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.

Abundance, The Book and it’s myopic viewpoint

I recently heard about a book called “Abundance” by Peter Diamandis and Steven Kotler, so I checked out Diamandis’ TED Talk available below. He has some good points, namely that technology will continue to create abundance for humans…..but his view is so incredibly human centered I am skeptical. It reminds me of when humans thought the earth was the center of the universe.

To make my point I counted the key words in his speech:

1. All words like “human”, “people” or references to people like “A lady…”, “All of you…”.
2. All words like “technology” or references to technology like “computer”, “phone”
3. All words like “oil”, “gas”, “fossil fuel”
4. The word “Abundance”
5. The words Nature, Plants, Animals or references like “Dog”, “Tree”

The numbers came out like this:
1. Human words: 85
2. Technology words: 65
3. Gas words: 1
4. The word “Abundance”: 3
5. Nature words: 0

His message? Humans are the only life forms that are important, and our intelligence will harness technology to stay great. Technology is what has driven us to our current success (not oil). Technology will give voices to the voiceless (all humans).

Plants, other animals and nature in general is not part of the equation, and if they are then they are simply raw materials to harness (sun, water etc).

He does mention nature three times and water fourteen times but they are purely human centric:
1. He uses the word “environment”: For survival reasons we are programmed to monitor how the “environment” can harm us. In this case the word is not really about nature but about the things surrounding humans (cars, muggers, falling pianos).
2. He mentions “climate crisis” and “species extinction”. It is used dismissively, though: Yes we have problems like climate crisis and species extinction but still humans are great.
3. His mentions of water are nothing to do with nature but merely about how humans can use technology to collect the raw material “water”.

I don’t disagree that technology and humans are great but I have a problem with his myopic view that excludes all other life forms. How different is his view to that of a white male a hundred years ago who’s decisions may have never considered women or blacks? I guess he is more open minded because he has broadened his view to include all humans?

His web site lists people who endorse his view:

  • Jeff Skoll Co-founder of eBay
  • Arianna Huffington CEO, Huffington post
  • Richard Branson Chairman, the Virgin Group
  • Ray Kurzweil Inventor & Author, The Singularity is Near
  • Matt Ridley Author, The Rational Optimist
  • Elon Musk CEO, Tesla Motors, Co-founder, PayPal
  • Stewart Brand Author, Whole Earth Discipline
  • Timothy Ferriss #1 NY Times bestselling author
These people are all pillars of what I call new capitalism, which is a slight variation on old capitalism. They love technology, they still love growth, and they exalt the power of humans to overcome all obstacles. Yea, they are pretty similar to old capitalists, the ones who trashed the planet in the first place.
Only this time they are way cooler. Capitalism Lite; still the great consumerist taste but with less guilt ridden calories.
They are in denial that all our progress so far has not been technology but an abundance of cheap energy in the form of oil. When a barrel of oil provides more energy than ten years of one person’s labor you have a society moving so fast they make a coke addict look sloth-like.
Could fuel have been the jumping stone to get us to our next technology driven stage? Maybe.
But that is not my point. When your global plan completely ignores the opinions of 99.99% of the planet’s life forms, as Diamandis’ human centered viewpoint does, you are being extremely narrow minded.
His presumption is that humans and technology can do it alone. We are that great. My answer to that is, first why would you want to? and, second, I don’t think so.
Diamandis and his cronies need to wake up and smell the flowers. They need to calm down from their oil induced speed binge and realize that the last hundred years were a blip in the planets overall trajectory. And we may very well look back at these hundred years as a momentary time of “irrational exuberance” and unrealistic bubbles.
Over the past several thousand years humans have moved from infancy to youth to middle age. I think it is time to start acting like adults and not teenagers with our father’s car, regardless of what fuel that car uses.
How a grown up would act is for another blog post, or more accurately it is all the blog posts on this site. The answers are not single bullets. They are a web of connected awareness that go far beyond humans and their meager little technological playthings.

I Am A Weed

How does the nature we find in and around our city reflect who we are?

There are two approaches, generally speaking, one can take when dealing with habitat conservation in urban areas. The first and most common is an attempt to return to the historical habitats that were found in the city long before it had been built. In this approach, native plants are protected and natural systems, like streams and fields, that have been disrupted by city infrastructure are attempted to be restored. This is undoubtedly a noble effort.

Another approach, however, is to accept that cities are new and unique environments, therefor nothing can be native to a city. Of course life is resilient and these new environments have been successfully colonized by a mix of historically native and non-native plants that have been able to survive despite the harsh, polluted conditions that cities provide. These plants are characterized by their abilities to be both flood and drought resistant. These traits make them well-suited to life in the shallow cracks of a sidewalk or building, which get flooded during a rain and, with no soil to retain the water, quickly become dry until the next shower. The collective term for this kind of flora is “spontaneous plants.”

ny green garden

Spontaneous plants offer a plethora of services for the urban environment. They, like all other plants, filter the air to provide us with oxygen while reducing the carbon imbalance of cities. Spontaneous plants supply green cover which in turn reduces the heat island effect and increases storm water retention. They create habitat for insects who become food for birds. Some even have the ability to remediate contaminated soils by absorbing heavy metals. And they provide greenery in otherwise gray and barren urbanscapes.

The Biophilia Hypothesis, introduced by Edward O. Wilson, asserts that humans hold an inherent bond with living systems. “Biophilia” literally means love for life. Our love of plants and animals, it is suggested, evolved from our dependence upon them for survival. Simply being around plants brings us pleasure so we protect them, and in doing so, we are also protecting food sources, shelter, and habitat for animals we might eat. This love can have a substantial impact on humans when they are exposed to nature. Studies have shown that people who live close to green spaces tend to be happier than those who don’t. Hospitals that look out onto greenery or that have images of nature in their rooms have faster rates of healing. Unsurprisingly, properties that have trees or are located near parks are worth more money. So it would seem that spontaneous plants are beneficial for urban areas because they fill in the cracks, literally and figuratively, with greenery. Yet many people do not see them this way.

Spontaneous plants can go by another name: “weeds.” Their presence is often seen as a sign of decay, poverty, or neglect. They are actively sought out for removal, even when their absence means an empty patch of gray.

During an informal interview with David Seiter, a visiting professor at Pratt Institute’s program for Sustainable Planning and Development and the principal of Future Green Studio, Seiter described the value of spontaneous plants in this way (I’m paraphrasing): Remember when you were a child. You would search for dandelions and make a wish while blowing away their fluffy white seeds? Or look at some of the fanciest restaurants in Brooklyn; you can see dandelion leaf salads on their menus. But when a dandelion sprouts up in a backyard, people are quick to pull them out or douse them in herbicides. How can something with so much value– a food source, a plaything, a bright yellow flower– be looked upon with so much disdain?

Seiter explained that society seems to find worth in things that are difficult. A garden of roses takes time to grow, requires careful attention, and must be watched with an anxious eye as its fragility makes it ever so prone to destruction. When we grow a rose successfully, we are proud. Meanwhile, the real hero here is the dandelion who has adapted to the harshest conditions, who can grow in seemingly impossible places with no help. Dandelions and other spontaneous plants don’t just survive, they thrive. It’s incredible really. But they are dismissed, despised even, for their independence and tenacity.

As Seiter recounted these thoughts, I felt a twinge of emotion stir inside me. I kept thinking, he is describing me. 

I would not be the first to make this connection. Look at Betty Smith’s novel, A Tree Grows In Brooklyn. The author likens the struggle of an immigrant family in Brooklyn to the Tree of Heaven, a common non-native and invasive weed in New York City. The plant struggles to find its place. It is neglected and trampled upon. But once it takes root, it puts up an inspiring fight, and despite the odds, eventually flourishes into a beautiful and imposing tree.

For those of us who are living and thriving in New York City, we can all look back on our struggle to take root. In the most obvious sense, think about apartment searching and how difficult it is to find your space in the city. Then there is the search for resources: money, food, air. We had to adapt to the harsh conditions of the city: pollution, noise, suffocating crowds, the heat, the cold. I’ve watched as friends have come and gone from the city, unable to “hack it,” and I’ve known many others simply too scared to try. We are the non-natives who have invaded and thrived.

And isn’t that what New York City has always been about? When I hear a native New Yorker claim ownership of the city, I admit I scoff at them. Were their parents or grandparents not immigrants? Aren’t immigrants the ones who built this city? Indeed the urban environment, especially that of New York’s, is a unique one that is constantly changing and growing and adapting. Nothing is static in the city and that is the way it should be; that’s progress. A dandelion is to a sidewalk crack as a hipster is to Williamsburg. It’s theirs now.

NY green design build firm

 So how do we better incorporate spontaneous plants and all their benefits into our city? Peter Del Tredici, senior research scientist at Arnold Arboretum and author of Wild Urban Plants of the Northeast, said, “I consider ‘weed’ to be a politically incorrect term. There is no biological definition of the term weed. It’s really a value judgment.” Certainly a change in perception is needed. As I was walking through Carroll Gardens this afternoon, I overheard a four year-old boy admonish his father for casually trampling a weed that had sprouted in the sidewalk, “Daddy, you’re stepping on the plant! Look out!” This child was seeing the plant as equal with all other plants, which he knows not to stomp on. He had not yet been taught by society that some plants have lesser value.

Why do we spend so much time and energy trying to green our cities with supposedly native or cosmopolitan plants who can’t hack it when there are so many plants that will willingly take their place? Why do we overly invest ourselves in removing spontaneous plants when they provide us with so much? Why do we devalue any object of nature?

More importantly, if these attitudes can be overcome, how do we prudently incorporate spontaneous plants into our cities? I do not believe by any means that these plants should have free reign. Surely a place like a graveyard or a government building overrun with weeds would send the wrong message. Still it is something we should consider.

landscape urbanism

Red Hook is my favorite Brooklyn neighborhood and is an excellent example of how spontaneous plants can bring life to an industrial wasteland. Take the above photo, for example. Without those plants, the dilapidated building would have a more foreboding and, quite frankly, ugly appearance. Their presence stirs a biophilic response in us. The success of life juxtaposes the death of a building. It reflects the burgeoning aesthetic of the 21 century which is characterized by an attraction to things that are vintage or down-to-earth (i.e. the wealthy hipster who dresses like a hobo.) I urge you to take a walk to Fairway or the Valentino Pier in Red Hook. Look out for walls of Queen Anne’s Lace lining chain-linked fences, then try to tell me that that is not beautiful.

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.

Riverside Park: Flushing Away the Porter Potties, Adding Composting Toilets

In 1875, Fredrick Law Olmsted designed Riverside Park, in 1935 Robert Moses built a highway right thought, but somehow the park has prevailed and it now going to be home to one of the greenest structures in the city – a composting toilet.

Riverside Park is home to the cities only clay tennis courts, this of course results in waits up to two and three hours. Waiting on a grassy knoll with perfect views of the Hudson doesn’t sound to shabby, but as nature calls, there is an inevitable need for a bathroom. That is why the Riverside Clay Tennis Association has decided to build a facility that will accommodate the needs of the parks visitors while being ecological, something public toilets rarely are.

The Riverside Tennis Association has commissioned Rick Cook of Cook & Fox to design a facility equipped with composting toilets and solar panels. Cook & Fox are also responsible for the LEED certified Bank of America tower across from Bryant Park.

Cook & Fox are taking this incredible concept one step further by designing this center to the Living Building Challenge standard, which is one of the toughest green standards out there. We recently wrote a blog about Bucky Fuller and the Living Building Challenge -a standard that we at Eco Brooklyn aspire to.

Living Building Challenge is difficult to achieve for multiple reasons, but the most challenging aspect of the standard is the water limitations. Buildings have a hard time qualifying for the LBC because bathrooms use such a large amount of water. The standard is so tough that in most places it is illegal, as most building codes demand a connection to water and sewer – the LBC standards call for net zero water (capturing rain water and discharging it onsite).

The design proposed a small building; the majority of it located underground, equipped with composting toilets, the compost generated by the toilets will be used to fertilize the greenery. Which is the one of the main reasons that we, at Eco Brooklyn ae so excited about this project. As green builders, we have installed numerous composting toilets. The design also incorporates photovoltaic panels which will be scattered in tree-like formations to power the building. Solar panels are another element that makes this project to actractive to NY Green Contractors like ourselves. We currently have plans to install solar panels on the rook and siding our the Ecpo Brooklyn Showhouse.

Composting toilettes typically use about three ounces of water compared to the 1.6 to 0.8 gallons per flush that typical high efficiency toilets use.

The design incorporates other green aspects besides composting toilets and solar panels. The architects plan to use recycled building materials, a green roof planted with native species and blast furnace slag in the concrete to circumvent the carbon heavy manufacturing process of cement.  For the past two weeks, we have been researching and planting native plants in the Show house. Last week we were weeding and plantings native species on a green roof in Brooklyn. We are excited to see that Cook + Fox have taken native species into account to create this NY design.

The Green design came out of necessity. The high water table and proximity to the Hudson makes it impossible to install a septic tank and leach field, in addition to those obstacles there is no connection to the city sewage system (sewage lines stop on the other side of the Henry Hudson Highway). Essentially their only option was to go green. Once again green building pushes past limitations that we humans have created for ourselves.

The bathrooms replace two portable toilets, a small brick shack and a repurposed shipping container that is used for storage; it will be built on the southeast corner of the courts.

The facility’s estimated cost is around $5.5 million and is scheduled to open this summer.

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.
