Steven J. Emmerich is a mechanical engineer in the Indoor Air Quality and Ventilation Group of the Energy and Environment Division (EED) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Mr. Emmerich is involved in research on indoor air quality, infiltration, ventilation and energy consumption in commercial and residential buildings. His current work includes studying the exposure to carbon monoxide from portable electric generators and research on ventilation and indoor air quality in high-performance (sustainable, green or net zero energy) buildings. His past work has included measuring the performance of residential IAQ control equipment and verifying the ability of multi-zone IAQ models to predict the impact of such equipment, applying combined multi-zone airflow models and building thermal models to study the energy impacts of poor building air-tightness and ventilation system control, and the application of computational fluid dynamics to study room air flow. Previously, as a research assistant at the University of Wisconsin-Madison, he applied building airflow and thermal load models to evaluate the energy and indoor air quality impacts of demand controlled ventilation systems.
Mr. Emmerich is a member of the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) and has published journal articles, project reports and technical papers on advanced ventilation systems, multi-zone airflow and indoor air quality modeling, residential indoor air quality, building energy use and computational fluid dynamics.
