Aspects and trends of building physics with regard to energy saving construction.

Stresses need to introduce sensible energy conservation measures into building and warns against superficially attractive solutions. Discusses reduction of ventilation heat loss by installation of mechanical ventilation incorporating heat recovery. Illustrates a mechanically ventilated dwelling with fresh air drawn into living areas and exhaust air leaving via the kitchen and WC. Treats further examples of mechanical ventilation which are adjusted according to necessary ventilation rates. Concludes by discussing trends in building construction concerned with conserving energy.
