The increasing incidence of health problems associated with 'tight buildings' can be partly blamed on the emis sion of volatile organic compounds (VOCs) derived from human activity and the presence of a range of synthetic furnishings, office equipment and building materials. The development and nature of both empirical (statisti cal) and deterministic (physical) indoor air quality mod els to predict the concentration of VOCs in indoor air has been reviewed. The review identified a number of physi cal parameters including air exchange, sorption/desorp tion processes, source emission rates and source emis sion decay profiles as important considerations in the establishment of a robust indoor air quality model. Such a model enables the health and safety professional to make cost-effective and informed decisions to improve indoor air quality and reduce health risk by minimising worker's exposure to contaminated air inside buildings.
