Title: ANSI/ASHRAE/IES/USGBC Standard 189.1 - The Indoor Skinny

Abstract

ANSI/ASHRAE/IES/USGBC Standard 189.1, first published in 2009, is the only national consensus standard that addresses the multiple building performance issues that define sustainable buildings. The standard contains design requirements that cover the wide range of building sustainability issues including site sustainability, water use efficiency, energy efficiency, indoor environmental quality (IEQ), and impact on the atmosphere, materials and resources, as well as construction and plans for operation. This presentation will provide an overview of the standard, including its organization and basic requirements. It will also take a deeper look at the indoor environmental quality requirements in the context of the perceived tension between energy efficiency and improved indoor environments. The standard’s IEQ requirement are largely based on ASHRAE Standard 62.1 (Ventilation for Acceptable Indoor Air Quality), which contains only minimum requirements in contrast to the high-performance goals of Standard 189.1. While Standard 189.1 does exceed 62.1 in some areas, the argument can be made that it is not consistent with high-performance IEQ. At the same time, achieving high-performance IEQ is viewed as having a significant cost in terms of energy. Reconciling these two goals is a challenge for the 189.1 committee as well as for designers and building owners who strive to provide high-performance buildings.

Bio

Dr. Andrew Persily is the Chief of Energy and Environment Division at the Engineering Laboratory, National Institute of Standards and Technology (NIST). He has performed research into indoor air quality and ventilation since the late 1970s. His work has included the development and application of measurement techniques to evaluate airflows and indoor air contaminant levels in a variety of building types, including large, mechanically ventilated buildings and single-family dwellings. These evaluation procedures include tracer gas techniques for measuring air change rates and air distribution effectiveness, contaminant concentrations measurements, and envelope airtightness. He has contributed to the development and application of multi-zone airflow and contaminant dispersal models.

Dr. Persily was a vice-president of the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) from 2007 to 2009, and is past chair of ASHRAE SSPC 62.1, responsible for the revision of the ASHRAE Ventilation Standard 62. He is currently chair of Standard 189.1, Design of High-Performance Green Buildings. He is a past chair of ASTM Subcommittee E6.41 on Air Leakage and Ventilation Performance and past vice-chair of subcommittee D22.05 on Indoor Air Quality. He was named an ASTM Fellow and an ISIAQ Fellow in 2002, and an ASHRAE Fellow in 2004.
