Presentation: ASHRAE Standard 62.1: Some of the Why, History, Technical Foundations, and Role of Indoor CO₂

_{By Andrew Persily}

_{National Institute of Standards and Technology (Gaithersburg MD not Boulder), retired}

This presentation will explain why ASHRAE has a Standard 62.1, with a reminder of why indoor air quality matters. This discussion will stress the important role of health in ASHRAE standards and other activities. Some of the history of how ASHRAE got to Standard 62.1 will also be reviewed. The technical basis for the standard’s requirements, specifically the outdoor air ventilation requirements, will also be explained, but with a strong reminder of the other critical requirements in the standard that cannot be ignored. The speaker will also cover the often misunderstood role of indoor CO₂ in the standard and overall in the field of indoor air quality and ventilation.

Dr. Andrew Persily is retired from the U.S. National Institute of Standards and Technology (NIST), where he held the position of Fellow and previously served as Chief of the Energy and Environment Division. He worked at NIST for more than four decades after earning a Ph.D. in Mechanical and Aerospace Engineering from Princeton University. His research focused on indoor air quality and ventilation in commercial and residential buildings, including the development and application of measurement techniques to evaluate airflow and indoor air quality performance and of multi-zone airflow and contaminant dispersal models. He has published more than 300 journal articles, conference papers and NIST reports. Dr. Persily was a vice-president of ASHRAE from 2007 to 2009, and is past chair of ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality) and Standard 189.1 (Design of High-Performance Green Buildings). He is a Fellow of ASHRAE, ASTM and ISIAQ, and recipient of the NIST Bronze, Silver and Gold medals.
