Abstract
The 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 building materials used in the construction of the CCHT (Canadian Centre for Housing Technology) 'Reference' house were collected and subjected to chamber testing. VOC emission rates were modeled from the results and entered into MEDB-IAQ. A simulation of the house construction and subsequent operation for an additional nine months was then run with the software 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 and analyzed by GC/MS. Prediction accuracy depended on source complexity, source identification and emitting area, and on sink effects. Trends in relative contributions of individual materials could be readily identified.
