Exposure Factors Handbook Chapter 19 (Update): Building Characteristics


EPA is announcing an update to Chapter 19 (Building Characteristics) of the Exposure Factors Handbook (2011 Edition). Refer to the About the Exposure Factors Handbook web page (under Downloads) for the latest information on the other handbook chapters.


This update includes new information and factors on building characteristics that affect exposure in an indoor environment that has become available since the Exposure Factors Handbook: 2011 Edition was released. The recommended values have been revised, as needed, to reflect the new information. This chapter addresses residential and non-residential building characteristics (volumes, surface areas, mechanical systems, and types of foundations), transport phenomena that affect chemical transport within a building (airflow, chemical-specific deposition and filtration, and soil tracking), information on indoor water uses, and on various types of indoor building related sources associated with airborne exposure and soil/house dust sources.
