Abstract

This study focuses on the influence of the use of air inlet and exhaust devices on the air change rates per hour (ACH) in 37 residential dwellings in the Netherlands. The ACH in living rooms varied from 0.1 to 1.9, whereas in bedrooms it varied from 0.1 to 3.6. Computations of relative humidity and carbon dioxide using a simple mathematical model and measured values of ACH revealed risks of poor indoor air quality in bedrooms and bathrooms. In building regulations more attention should be paid to ventilation requirements for bedrooms and bathrooms.
