Ventilation of residential buildings. Beluftung von wohngebauden.

Investigates the effects of five different ventilation strategies on the annual energy consumption for heating and warm water of residential (family) homes. The strategies are: (1) natural ventilation, (2) mechanical ventilation and three forms of exhaust plants. Uses weather data from Portland, Oregon and Great Falls, Montana as examples of very different climatic conditions and heating/cooling requirements. The University of Wisconsin TRNSYS program was used for numerical simulation. Calculations show that energy savings achieved by sealing the building surfaces and installation of mechanical ventilation are of the same order as those achieved by improved thermal insulation of outside walls.
