Net Zero Passive House Energy Efficient Solar Heat
A hobbyist's dream, this workshop building for restoring old cars needed to stay at 60-80 degrees Fahrenheit year-round --with NO FURNACE OR AC! Accomplished with straw bale walls, Bio-based spray foam insulation, green roofs, and solar thermal radiant floor heating. It has performed to spec for many years (and many classic cars)!
