Geothermal heating for a housing project originally built for veterans after WWII, Wheeler Terrace has been retrofitted to use green energy.
You never think of DC for geothermal heating and cooling. It's always Iceland or someplace like that. And you certainly don't think of affordable housing, either.
But here it is in DC, "Located in the Washington Highlands community, Wheeler Terrace is the first affordable housing complex in the District expected to meet both the Enterprise Green Communities Criteria for affordable housing and the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Gold standard." from The Washington Informer.
The innovation is expected to bring a 25% reduction in energy consumption for Wheeler Terrace. Pretty good!
