Abstract
Globally over 100,000 different chemicals are manufactured every year (Levi et al. 2018). It is impossible to measure the fate of all of these chemicals in the wide range of indoor environments. The Indoor Environmental Concentrations in Buildings with Conditioned and Unconditioned Zones (IECCU) model, developed by the United States Environmental Protection Agency, is one model that can be used to predict potential indoor concentrations. IECCU simulates multiple well-mixed indoor zones using time dependent airflow and temperature inputs. IECCU can model emissions of semi-volatile organic compounds (SVOCs) using a mass transfer-based approach.
