CONTAM 2.1 Supplemental User Guide and Program Documentation

October 22, 2003
Author(s)
George Walton, William Stuart Dols
CONTAM is a general purpose, multi-zone (nodal) airflow and contaminant transport analysis tool that can be used to determine inter-zone pressure differences, airflow rates and contaminant transport in complex building structures. This tool was developed

Impact of Natural Ventilation Strategies and Design Issues for California Applications, Including Input to ASHRAE Standard 62 and California Title 24-Report on Task 4.4.3a and 4.4.3b of CEC-EEB RMT Project

October 1, 2003
Author(s)
Steven J. Emmerich, Andrew K. Persily, William S. Dols, James W. Axley
Natural ventilation has the potential to reduce the energy required for cooling and ventilating commercial buildings while still providing acceptable thermal comfort and indoor air quality. While a recent surge of interest in Europe has advanced natural

LoopDA -- A Natural Ventilation System Design and Analysis Tool

August 1, 2003
Author(s)
William S. Dols, Steven J. Emmerich
The Loop Equation Design Method has been proposed for sizing ventilation airflow components of natural and hybrid ventilation systems. While the loop design method has been demonstrated on a limited basis, the method has been automated in order to better

November 1, 2002
Author(s)
William S. Dols, George Walton
This manual describes the computer program CONTAMW version 2.0 developed by NIST. CONTAMW is a multizone indoor air quality and ventilation analysis program designed to help you determine: airflows and pressures infiltration, exfiltration, and room-to-room

Natural Ventilation Review and Plan for Design and Analysis Tools

August 1, 2001
Author(s)
Steven J. Emmerich, William S. Dols, James W. Axley
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 natural

NIST Multizone Modeling Website

April 2, 2001
Author(s)
William S. Dols
This report presents an overview of the NIST Multizone Modeling Website developed by the Building and Fire Research Laboratory of the National Institute of Standards and Technology (NIST). Multizone modeling refers to the calculation of airflows, pressure

A Tool for Modeling Airflow & Contaminant Transport

March 1, 2001
Author(s)
William S. Dols
Multizone modeling refers to annalysis techniques that use a simplified, zonal representation of a building to study building airflows, pressure differences, and contaminant transport. Each zone is assumed to have uniform temperature, pressure, and

Air Change Effectiveness Measurements in Two Modern Office Buildings

January 1, 1994
Author(s)
Andrew K. Persily, William S. Dols, Steven J. Nabinger
Local age of air and air change effectiveness were determined in two office buildings using tracer gas techniques to study the applicability of the associated measurement procedures in mechanically ventilated office buildings. Measurement issues examined
