Here is a short video we threw together of the Passive House renovation in Harlem. The video mostly discusses the budgeting of the project.
Now that the construction is for the most part done I think that our initial budget of $175/sq.ft is not sustainable. Of course it is great for the client in the [...]

If you enjoy the video, please give us a “Like” [...]
The windows we ordered finally arrived to our Harlem Passive House. They’re not your typical windows though by any means, and unfortunately we couldn’t get them USA made. These are triple pane windows. They’re pretty heavy compared to a typical window of the same size, and a heck of a lot more expensive. As a [...]

Here is a discussion between myself and other Passive House people regarding what ventilation system to use in the New York Passive house Eco Brooklyn is building.

In this Passive House project we are [...]
It is striking that despite the many green building going on in the US that there still remains some blaring gaps in our knowledge and available products.
I encountered another of these gaps recently in my search for a good front door for a Brooklyn Passive House style brownstone. I was looking for something super [...]
With our new Passive House building standard a key component of our green brownstone renovations are the ERV or HRV, or Energy Recovery Ventilator and Heat Recovery Ventilator.
Both units perform the same task of clearing the house of stale air and providing it with fresh air from the outside. In a “normal” brownstone this [...]
