The interaction between physical and social-psychological factors in indoor environmental health

Indoor environmental health is now recognized as an important factor in preventing respiratory health problems in the United States. It is also a concern in Canada due to the amount of time that Canadians spend indoors because of cold weather and the potential for increased time indoors during the summer if the climate warms. The negative health effects are often labeled as sick building syndrome, but diagnosing a building or its occupants as sick is complicated by the variety of symptoms, the presence of chronic versus acute symptoms and social and psychological (sociopsychological) factors that may reduce the effectiveness of an engineering solution. As a case study, the contribution of various factors to indoor environmental health, in three buildings at the University of Toronto, was examined using five different methods. The results indicate that the inhabitants of the buildings consider features other than air quality in considering building health such as design, maintenance, funding cuts and socio-psychological factors.
