AbstractThe ability of the Material Emission Database and Indoor Air Quality simulation program(?MEDB-IAQ?) to use small chamber test results to model volatile organic compound (VOC)profiles in a newly constructed 2-storey single family home was evaluated. Selected buildingmaterials used in the construction of the CCHT (Canadian Centre for Housing Technology)?Reference? house were collected and subjected to chamber testing. VOC emission rateswere modeled from the results and entered into MEDB-IAQ. A simulation of the houseconstruction and subsequent operation for an additional nine months was then run with thesoftware package. Air exchange rate data from the house was also used as model input.Predicted VOC results were then compared with air samples taken from the house andanalyzed by GC/MS. Prediction accuracy depended on source complexity, sourceidentification and emitting area, and on sink effects. Trends in relative contributions ofindividual materials could be readily identified.
