detail footings for passive house performance... or rather, what does not happen. In mainstream 'built to code' buildings, the concrete continuously conducts thermal energy into the ground. Concrete moves heat in or out of buildings very efficiently, sort of like copper conducts electricity very efficiently. Not here; we are effectively isolating and containing the thermal energy.
30 Off The Grid And Self-Sustaining Earthship Homes http://theownerbuildernetwork.co/3f2t This home uses one of the world’s biggest waste problems as it’s basic building material. Can you guess what that is? The result is an incredibly strong, thermally stable home. It can also look fantastic as you can see here!
The Behar Greenhouse is a model of passive solar sustainability. The frame is made of locally milled Black Locust timber. The in-bed thermal air exchange system and expandable end wall allow for tight control of temperature. The growing tables are suspended from overhead tracks that allow for more efficient use of space and the base vents give access into the cold frame along the base of the south wall to harden off young plants.
