Thermogram Shows the Extreme Efficiency of New York's First Passivhaus Building

by Andrew Price

Loadingdock5, a Brooklyn-based architectural studio founded by a pair of Viennese expats, is finishing work on an impressive new building at 174 Grand Street in Williamsburg. It's the modern-looking black one in the picture above.

The darker, purpler areas on the image are cooler. The lighter, oranger areas are warmer. As you can see, the building in the middle, the Passivhaus building, has very little orange. That's because it doesn't leak heat. And its windows are so well insulated that they're cooler than the building's sides. This is, literally, what energy efficiency looks like.

As TreeHugger notes, the heating bills for this building are going to be significantly lower than average thanks to "a shitload of insulation, careful detailing and controlled amounts of high quality glazing."
