Abstract: First House II is a self regulating, solar powered, air cycle machine. Thermo radiation and photovoltaic conversion interact proportionally to moderate [climatic] extremes. It incorporates the natural cycles for water, waste, garbage, household dirt and for air purification. The interior cantilever post and beam skeleton, with innovative joinery, is sheathed in rigid non-biodegradable skin to form a permanent, low maintenance structure. The interior and exterior geometry for radiant energy absorption also utilizes skin openings, temperature and pressure differentials to control air quality and flow. [Openings for doors], windows and holes are precision cut from the skin and [then] reinstalled to prevent unintentional convection, conduction or radiant energy loss. Pre-manufactured interchangeable parts permit phased construction or expansion with no onsite waste or refuse.
