Living in a passive solar, geothermal envelope house we finished in 2005 from a kit delivered from Enertia Building Systems. Radiant floor, hot water heat powered by 50 gal., LP gas water heater. Auxiliary heat (well, more than auxiliary if we’re home) from RAIS Atlas soapstone-clad wood stove. Hoping to build a timber-framed, solar car port. Prefer to avoid panels on the house–even though that placement would be best exposure–several degrees east of due south.
