Estimating Building Material Contributions to Indoor Air Pollution
Many professionals and scientists are attempting to identify low-emitting building materials during building design. Others need to model indoor air quality (IAQ) for problem building investigations or for research. Manufacturers improve their products' performance using such modeling. These efforts focus on volatile organic compound (VOC) emissions from building materials. A step-wise procedure for the use of IAQ modeling may ultimately improve building performance. A procedure is described and its important steps are illustrated in this paper. Reasonably accurate estimates can be made based on careful use of available data. Barriers to reliable use of modeling include insufficient data characterizing emissions from many important indoor pollutant sources.
