Abstract

A critical aspect of air pollution exposure assessments is estimation o. The air exchange rate (AER) for various buildings where people spend their time. The AER, which i. The rate of exchange of indoor air with outdoor air, is an important determinant for entry of outdoor air pollutants and for removal of indoor-emitted air pollutants. This paper presents an overview and critical analysis o. The scientific literature on empirical and physically based AER models for residential and commercial buildings. The models highlighted here are feasible for exposure assessments as extensive inputs are not required. Models are included fo. The three types of airflows that can occur across building envelopes: leakage, natural ventilation, and mechanical ventilation. Guidance is provided to selec. The preferable AER model based on available data, desired temporal resolution, types of airflows, and types of buildings included i. The exposure assessment. For exposure assessments with some limited building leakage or AER measurements, strategies are described to reduce AER model uncertainty. This review will facilitat. The selection of AER models in support of air pollution exposure assessments.
