BFRL Develops Searchable Databases for Indoor Air Quality Analysis

BFRL has developed a series of searchable databases of indoor air quality (IAQ) model input data that may be used to estimate building contaminant concentration levels and associated occupant exposures. Database structures have been designed for compiling volatile organic compound (VOC) emission rates from building materials, particle and inorganic gas emission rates from indoor combustion sources, particle deposition rates, VOC sorption rates, and particle filtration efficiencies. Although many of these input data are available in the literature, they have not previously been compiled in a readily accessible format. As a result of BFRL’s efforts, the IAQ community now has a standard format to organize model input data for assessments of data quality, trends, and gaps, as well as for convenient use in IAQ models. In addition, BFRL developed ContamLink, a software tool to search the databases and create data libraries for use in the indoor air quality and ventilation model CONTAM. These databases and the software tool have been documented in NISTIR 7364 and are available at the CONTAM Web site, http://www.bfrl.nist.gov/IAQanalysis/software/CONTAMLINKdesc.htm.
