Abstract Exposure, Version 2 is a model for calculating individual exposure to indoor air pollutants from indoor sources is presented. The model is designed to calculate exposure due to individual, as opposed to population, activity patterns, and source use. The model uses data on source emission, room-to-room air flows, air exchange, with the outdoors, and indoor sinks to predict concentration-time profiles for all rooms. The concentration-time profiles are then combined with individual activity patterns to estimate exposure. The model allows analysis of the effects of air cleaners located in with/or both the central air circulating system or individual rooms on IAQ and exposure. The model allows simulation of a wide range or source including long term steady state sources, on/off sources, and decaying sources. Several sources are allowed in each room. The model allows the analysis of the effects of sinks re-emissions on Indoor Air Quality (IAQ). The results of test house experiments are compared with model predictions. The agreement between predicted concentration-time profiles and the test house data is good. The disk contains both the executable EXE, files and source code files for the model. The files on the disk are in self extracting archives prepare using the public domain LHARC program.
