81. Modeling the Performance of a Naturally Ventilated Commercial Building with a Multizone Coupled Thermal/Airflow Simulation Tool
Published: 6/1/2002
Authors: James W Axley, Steven J Emmerich, George Walton
Abstract: Naural ventilation systems have long been employed in European residences to control indoor air quality. European building designers have turned to natural ventilation to control air quality and cool commercial and institutional buildings as well, h ...

82. Airflow and Aerosol Transport Modeling in Hart Senate Office Building
Published: 5/23/2002
Authors: Steven J Emmerich, Cynthia H. Reed, Andrew Keith Persily
Abstract: A modeling study of airflow and contaminant transport in the Hart Senate Office Building (HSOB) was performed to obtain insight into the transport of anthrax spores within the building after a short-term release in October 2001. This analysis employe ...

83. Natural Ventilation Review and Plan for Design and Analysis Tools
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6781
Published: 8/1/2001
Authors: Steven J Emmerich, William S Dols, James W Axley
Abstract: Natural ventilation has the potential to reduce first costs and operating costs for some commercial buildings while maintaining ventilation rates consistent with acceptable indoor air quality. While a recent surge of interest in Europe has advanced ...

84. State-of-the-Art Review of CO^d2^ Demand Controlled Ventilation Technology and Application
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6729
Published: 7/1/2001
Authors: Steven J Emmerich, Andrew Keith Persily
Abstract: The control of outdoor air intake rates in mechanically ventilated buildings based on indoor carbon dioxide (CO^d2^) levels, often referred to as CO^d2^ demand controlled ventilation (DCV), has the potential for reducing the energy consumption associ ...

85. Validation of Multizone IAQ Modeling of Residential-Scale Buildings: A Review
Published: 1/1/2001
Author: Steven J Emmerich
Abstract: This paper reviews validation studies of the application of multizone indoor air quality (IAQ) models to residential-scale buildings. This review focuses on empirical verification efforts, although models have also been subjected to analytical verif ...

86. Measurement and Simulation of the IAQ Impact of Particle Cleaners in a Single-Zone Building
Series: NIST Interagency/Internal Report (NISTIR)
Report Number: 6461
Published: 2/1/2000
Authors: Steven J Emmerich, Steven J Nabinger
Abstract: This report describes the initial phase of an effort to evaluate the ability of multizone airflow and pollutant transport models to predict the impact of residential IAQ control technologies. Measurements of the performance of several particulate ai ...

87. Energy Impacts of Infiltration and Ventilation in U.S. Office Buildings Using Multizone Airflow Simulation
Published: 6/1/1999
Authors: Andrew Keith Persily, Steven J Emmerich
Abstract: With exception of a few analyses of the impacts of ANSI/ASHRAE Standard 62-1989 and energy use in specific buildings, the energy used in commercial buildings due to infiltration and ventilation flows has received little attention. However, as improv ...

88. Application of a Large Eddy Simulation Model to Study Room Airflow.
Published: 1/1/1998
Authors: Steven J Emmerich, Kevin B McGrattan
Abstract: A three-dimensional, large eddy simulation (LES) model developed for studying the transport of smoke and hot gases during afire in an enclosure is described. The model uses finite digerence techniques to solve the Navier-Stokes equations with an appr ...

89. Application of a Multi-Zone Airflow and Contaminant Dispersal Model to Indoor Air Quality Control in Residential Buildings.
Published: 9/27/1994
Authors: Steven J Emmerich, Andrew Keith Persily, George Walton
Abstract: A new multizone airflow and contaminant dispersal model CONTAM93 is described, along with a demonstration of its application in a study of ventilation and contaminant control in single-family residential buildings. While CONTAM93 is based on existing ...

90. Predicting Gaseous Air Cleaner Performance in the Field
Published: Date unknown
Authors: Cynthia H. Reed, Steven J Nabinger, Steven J Emmerich
Abstract: As part of an ongoing effort to better understand the performance of indoor air cleaners in real buildings, the National Institute of Standards and Technology (NIST) has completed a series of air cleaner field tests and model simulations. This paper ...
