101. A Software Tool for Analyzing Building Airflow and Airborne CBR Agent Concentrations
Published: 12/31/2007
Authors: William S Dols, Andrew Keith Persily
Abstract: Contaminant concentrations that result within buildings in response to airborne chemical, biological and radiological (CBR) events are due to a complex interaction between the building construction, ventilation system performance and weather conditio ...

102. Development of a Field Test to Measure Gaseous Air Cleaner Performance in a Multizone Building
Published: 10/1/2007
Authors: Cynthia H. Reed, Steven J Nabinger, Andrew Keith Persily, Victor Henzel
Abstract: The performance of gaseous air cleaners for commercial and residential buildings has typically been evaluated using test protocols developed for a controlled laboratory chamber or a test duct. It is currently unknown whether laboratory measurements r ...

103. Improving the Reliability of VOC Emissions Testing of Building Products
Published: 10/1/2007
Authors: Cynthia H. Reed, Andrew Keith Persily, Steven J Nabinger, John C. Little, Steven Cox
Abstract: Manufacturers of building materials and furnishings are increasingly using emissions chamber testing to demonstrate low volatile organic compound (VOC) emissions from their products and to qualify for low-emitting certification and sustainable labe ...

104. Measuring Airtightness at ASHRAE Headquarters
Published: 9/1/2007
Authors: Steven J Emmerich, Andrew Keith Persily, Terry Brennan

105. ASHRAE Standard 62.1: Problems, Perceptions and Panaceas?
Published: 3/1/2007
Authors: Andrew Keith Persily, Dennis Stanke, Gordon Holness, Richard Hermans
Abstract: ASHRAE Standard 62 was first published in 1973, with the title Standards for Natural and Mechanical Ventilation [REF]. The most recent version (designated as 62.1 and titled Ventilation for Acceptable Indoor Air Quality) was published in 2004, with ...

106. Building Retrofits for Increased Protection Against Airborne Chemical and Biological Releases
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 7379
Published: 3/1/2007
Authors: Andrew Keith Persily, Robert E Chapman, Steven J Emmerich, William S Dols, Heather Davis, Priya D Lavappa, Amy S. Rushing
Abstract: Due to concerns about potential airborne chemical and biological (chembio) releases in or near buildings, building owners and managers and other decision makers are considering retrofitting buildings to provide some degree of protection against such ...

107. Airtightness of Commercial Buildings in the United States
Published: 9/21/2005
Authors: Steven J Emmerich, Andrew Keith Persily
Abstract: In 1998, Persily published a review of commercial and institutional building airtightness data that found significant levels of air leakage and debunked the myth of the airtight commercial building. This paper updates the earlier analysis for the U ...

108. Ventilation Rates in U.S. Office BuildingsFrom the EPA Base Study
Published: 9/1/2005
Authors: Andrew Keith Persily, J Gorfain, Greg Brunner
Abstract: The EPA BASE study involved indoor environmental measurements in 100 U.S. office buildings. This paper presents an analysis of the measured outdoor air ventilation rates, including comparisons with the requirements in ASHRAE Standard 62. The outdoor ...

109. What We Think We Know About Ventilation
Published: 9/1/2005
Author: Andrew Keith Persily
Abstract: The amount of outdoor air provided to occupied spaces is one of the most important determinants of indoor air quality, but many critical questions and misunderstandings still exist regarding outdoor air ventilation. First, given the importance of ven ...

110. Ventilation Design and Performance in U.S. Office Buildings
Published: 4/30/2005
Authors: Andrew Keith Persily, J Gorfain
Abstract: Building ventilation is a primary determinant of indoor air quality (IAQ) as it impacts contaminant concentrations and occupant comfort in terms of the perception of odor and irritation. However, relatively few measurements of office building ventila ...
