MAKING THE CASE FOR REDUCING VENTILATION REQUIREMENTS THROUGH SELECTION OF LOW-EMISSION MATERIALS

摘要

Most ventilation rates have not been based on pollutants emitted from building materials and furnishings. An approach using the existing Material Emission Database and Indoor Air Quality computer model is presented. The approach examines by how much ventilation rates can be reduced through control of indoor sources of air pollutants while still maintaining acceptable IAQ for residential settings and the consequences on indoor air contaminant concentrations of reductions in ventilation rates below current design requirements.
