Essay:
Dynamic insulation"A dynamically insulated envelope\ which permits the movement of air moisture etc through the external walls of a building is constructed using air permeable materials. Air flows through the wall driven by a difference in pressure between inside and out created by fans or stack effect. In essence air flowing in through the wall picks up the heat that is being conducted outwards. The heat lost to the outside can be reduced to practically zero by quite small air flows." - Taylor et al., 1999, The building envelope as an air filter
