Thermal comfort and air quality were studied in three multi-family buildings located in urban environments. Measurements of air velocities close to the supply devices are presented along with measurements of CO, TVOC, NO and N02. In addition, particle measurements were carried out to check the filter efficiency in one of the buildings (Sl) which is specially designed for people with allergy problems. The total air change rate for this building is higher than for normal residential buildings and three different types of air filter are installed in the ventilation system.
This paper critically examines the underlying premises of indoor climate control technologies and the HV AC industry (heating, ventilating, air-conditioning). It questions whether 'total environmental control' is possible, effective and desirable. The paper also reviews the methods and terminology of thermal comfort science focusing on the question of predictability of people's environmental preferences.
