DAMPNESS IN BUILDINGS AND HEALTH. BUILDING CHARACTERISTICS AS PREDICTORS FOR DAMPNESS IN 8 681 SWEDISH DWELLINGS

摘要

Questionnaire data on 8 681 dwellings included in the Swedish study "Dampness in Buildings and Health" has been analyzed for associations between dampness indicators, perceptions of indoor air quality and building characteristics such as time of construction, type of ventilation and type of foundation. Visible mold or damp stains were reported in 1.3 and 1.6% of single-family and multi family houses respectively, dampness connected to the floor in 6.5 and 13.9% and condensation on windows in 12.5 and 16.9%. "Stuffy air" was reported in 22.3 and 42.8%, "Moldy odor" in 3.9 and 5.8% and perception of "Dry air" in 17.3 and 33.7% respectively. Older buildings and the use of natural ventilation were associated with increased frequency of dampness indicators as well as to increased frequencies of complaints on bad indoor air quality.
