This study addresses relationships between indoor air quality (IAQ), occupant health and comfort, and mitigation strategies. The major objectives are to relate direct measurements of IAQ to building related illness and sick building syndrome and to increase the understanding of the relationships between occupant health, building system operation, and air quality. The study uses a series of controlled interventions in large, mechanically ventilated office buildings with simultaneous measurements of IAQ parameters and surveys of occupant health and perception. The experimental interventions may include variations in fresh air exchange, ventilation rates, HVAC scheduling/operation, humidity, night-time purge, filtration, and cleaning. A psychosocial survey will account for job-related and personal cofactors which may affect reporting results of the IAQ and symptom survey. The blind, controlled and repeated measures design of the study is designed to provide high discriminatory power; experimental controls and carefully controlled interventions will minimize effects of confounding factors. Statistical analyses of survey results in conjunction with various indoor air quality indicators will adjust for confounding and will indicate controlling factors. The study should help to identify and quantify effects of various indoor pollutants and potential mitigation strategies, and should help to improve protocols for building investigations.
