Ventilation and indoor air quality in new Norwegian dwellings.

SINTEF, The Foundation for Scienti f ic and Industrial Research at the Norwegian Institute of Technology, has monitored a number of experimental low-energy houses, and also undertaken measurements in some other houses to establish the energy consumption, air tightness, ventilation rates etc. Some of the experimental houses are extremely air tight. In connection with these measurements we have made some observations on the occupants behavior related to ventilation, and their satisfaction with the ventilation system.
