1. Analysis of the NIST Commercial and Institutional Building Envelope Leakage Database
Published: 5/22/2013
Authors: Steven J Emmerich, Andrew Keith Persily
Abstract: In 1998, NIST 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 (Persily 1998). Since then, NIST has expanded and mai ...

6. Indoor ultrafine particles of outdoor origin: importance of window opening area and fan operation condition.
Published: 2/5/2013
Authors: Dong H. Rim, Lance L. Wallace, Andrew Keith Persily
Abstract: Airborne ultrafine particles (UFP) have been associated with human mortality and morbidity. Human exposure to ambient UFP occurs indoors due to entry of UFP into buildings. This study investigates UFP entry as a function of building operating conditi ...
