21. Measured CO Concentrations at NIST IAQ Test House from Operation of Portable Electric Generators in Attached Garage – Interim Report
Steven J Emmerich, Liangzhu Wang
The U.S. Consumer Product Safety Commission (CPSC) is concerned about the hazard of acute residential CO exposures from portable gasoline powered generators that can result in death or serious and/or lasting adverse health effects in exposed individu ...
22. Modeling the Effects of Outdoor Use of Portable Gasoline Powered Generator Exhaust on Indoor Carbon Monoxide Exposure
Steven J Emmerich, Leon Wang
The U.S. Centers for Disease Control and Prevention (CDC) has reported that up to half of non-fatal CO poisoning incidents during the hurricane seasons in 2004 and 2005 involved generators operated outdoors but within seven feet of the home. We condu ...
23. Ultrafine Particles: 3 Years of Measurements in the NIST Test House
Lance L. Wallace, Andrew Keith Persily, Steven J Emmerich, Dong H. Rim, Chi Phuong Hoang, Cynthia H. Reed, Wang Fang, M E. Greene, Jung I. Choi
NIST has supported research characterizing ultrafine particle sources and dynamics for more
than a decade. Over 90 % of ultrafine particles (UFP) produced by stovetop cooking on both gas
and electric stoves were <10 nm in diameter. Emission rates o ...
24. Simultaneous Solutions of Coupled Thermal Airflow Problem for Natural Ventilation in Buildings
Steven J Emmerich, William S Dols, Liangzhu (Leon) Wang
Natural and hybrid ventilation are sustainable building ventilation strategies, where airflow is driven naturally by thermal buoyancy and/or wind forces other than pure mechanical means. The simulation and design of these systems thus need to conside ...
25. ASHRAE Standard 62.2: What is it, what’s new, and who’s using it
Steven J Emmerich
Readers of the November 2010 IAQ Applications column by Bud Offermann learned about a large, residential IAQ study that highlighted the importance of mechanical ventilation in U.S. homes. ASHRAE Standard 62.2-2010 Ventilation and Acceptable Indoor Ai ...
26. In situ Experimental Study of Carbon Monoxide Generation by Gasoline-powered Electricity Generator in an Enclosed Space
Liangzhu Wang, Steven J Emmerich
About 98 % of generator-related carbon monoxide (CO) fatalities in recent years were caused by running operating gasoline-powered generators in enclosed spaces. With an increasing market demand for portable, gasoline-powered electric generators, a be ...
27. Indoor Air Quality in Sustainable, Energy Efficient Buildings
Andrew Keith Persily, Steven J Emmerich
Building designers, contractors, owners and managers have long been challenged with providing quality indoor environments at a
reasonable energy cost. Current efforts to improve building energy efficiency, including goals of netzero energy use, are ...
28. Ventilation Rate Distributions for U.S. Housing
Andrew Keith Persily, Amy Musser, Steven J Emmerich
A set of 209 dwellings that represent 80 % of U.S. housing stock was used to generate frequenc distributions of residential ventilation rates. The set of homes is based on an anal sis of the 1997 U.S. Department of Energ s Residential Energ Consum ...
29. Modeling the Effects of Outdoor Gasoline Powered Generator Use on Indoor Carbon Monoxide Exposures Phase II
Technical Note (NIST TN)
Wang Liangzhu, Steven J Emmerich, Ryan Powell
The U.S. National Institute of Standards and Technology (NIST) conducted a study for CDC to examine the impact of distance of gasoline-powered portable electric generators on indoor CO exposure. The study was based on computer simulations of CO trans ...
30. Effect of Air Infiltration and Ventilation
Andrew Keith Persily, Steven J Emmerich
This chapter discusses the role of air infiltration and ventilation in building moisture transport. While water vapor diffusion can be a very important moisture transport mechanism, as discussed in other chapters, bulk air movement via infiltration a ...
