AbstractVolatile organic compound (VOC) emissions from building materials are typically tested under standardized conditions (i.e., at ~23 C and 50% RH). While a standardized testing condition is desirable to produce comparable and compatible emission data, it is also necessary to understand the effects of various environmental conditions on material emissions. Experiments were designed to quantify the effects of environmental factors including air velocity and temperature on the VOC emissions from solvent-based paint. To report the effects in a quantitative format, the varied levels of environmental factors were correlated with coefficients of a mass-transfer model accounting for internal diffusion and surface evaporation. It was observed that diffusion coefficient is a function of air temperature, while evaporation coefficient is a function of air velocity.
