Greenhouse, stage 2: External, grand greenhouse covers the face of the entire structure, creating a much larger area for biocells between the outer grand shell and the formerly external greenhouse lein-to. Although the lein-to will no longer catch as much solar radiation to disperse into the home -as plants grow to shade it- the grand greenhouse catches MORE radiation, which can be vented into the hallway/ventalaton corridor as needed to heat the internal living space.
Building zero-energy, passive solar, high thermal mass homes (HTM) homes. One key is interior planting beds for heat retention and year-round crops.
Earth Tubes passive heating/cooling system instead of A/C or heating. My dad has told me about this before. I want this in my home if I can talk Josh into it.
Earthship greenhouse. Mine would have more edibles, not tropicals. Pretty, but ya can't eat 'em.
