EFFICIENT HOUSE: AN EFFICIENT, HEALTHFUL AND DURABLE BUILDING SYSTEM USING DIFFERENTIAL AIRFLOW AND HEAT CONTROL ACROSS AN AIR PERMEABLE HEAT REFLECTIVE EXTERNAL ENVELOPE ASSEMBLY

摘要

An efficient building design uses airflow across dynamic exterior walls to counteract heat transfer thereacross. The dynamic walls feature a stud wall layer with air- permeable wall insulation in the stud cavities, an air-permeable external insulation layer with rigid insulation panels, a building wrap layer, and heat reflecting material arranged to reflect radiant heat back away from the wall in both directions. Monitoring and control systems monitor conditions associated the dynamic wails and control airflow therethrough in response to the monitored conditions. The control system is switchable between a heating mode, in which the the dynamic walls are depressurized to draw air into an air distribution system from the external environment, and a cooling mode in which inside air from a lower level of the building's interior space enters the dynamic wall structures through the air distribution system and is forced out of the building through the dynamic walls.
