Air management in energy conserving passive solar houses

Analyses the problem of air management in energy conserving passive solar houses and discusses cost effectiveness of various alternative scheme. Use of polythene sheeting to form anair-tight membrane aims to reduce uncontrolled ventilation rate to 0.05 air changes per hour. Discusses problem of indoor air pollution and suggests adding venting windows and air-to-air heat exchangers. The need for internal air circulation is answered by ceiling fans or a central forced air system. Concludes that air management in low energy passive solar houses is significantly different from that in standard housing.
