General Energy Use, Strategies and Systems

Energy Strategies:

The house integrates three solar energy systems: passive solar space heating, solar domestic hot water, and a solar photovoltaic system.
Passive solar space heating: direct solar heat gain through high SHGC south-facing windows, with the finished 4.5” thick concrete floor providing the thermal mass for thermal collection and storage. Concrete slab is passive with no additional radiant heat source, and to assure thermal comfort for occupants it has been designed as a thermal island, with R-30 under slab and R-30 overall slab edge insulation and additional below grade R-10 exterior foundation wall insulation.
Solar domestic hot water: Two SunEarth EC-32 (4'x8') flat panel collectors, (SunEarth rebranded) Rheem Solaraide HE 80G tank with heat exchanger and electric element backup (240V, 4500 W).
