Field Measurement of Ventilation Rates

March 18, 2015
Author(s)
Andrew K. Persily
Ventilation rates have significant impacts on building energy use and indoor contaminant concentrations, making them key parameters in evaluating building performance. Ventilation rates have been measured in buildings for many decades and there are mature

Exothermic Reaction of Halogenated Hydrocarbons: WORKSHOP PROCEEDINGS

March 13, 2015
Author(s)
Gregory T. Linteris, Jeffrey A. Manion
A workshop was held at NIST Gaithersburg on October 27 and 28, 2014 to discuss the exothermic reaction of halogenated hydrocarbons. The industries that gathered to discuss the topic were the fire suppression, fire suppression in aircraft, and Heating

EFFECT OF SIDING TREATMENT ON FIREBRAND PRODUCTION FROM BUILDING COMPONENTS

February 2, 2015
Author(s)
Samuel Manzello, Sayaka Suzuki
Wildfires which spread into a community, commonly known as Wildland-Urban Interface (WUI) fires, is a significant problem all over the world. Post-fire investigations have suggested that firebrands are the major cause of structure ignitions. Yet, few

Experimental and Numerical Simulations of the Gas-Phase Effectiveness of Phosphorus Compounds

February 2, 2015
Author(s)
Nicolas Bouvet, Gregory T. Linteris, Valeri I. Babushok, Fumiaki Takahashi, Viswanath R. Katta
The effectiveness of phosphorus-containing compounds as gas-phase combustion inhibitors varies widely with flame type. To understand this behavior, experiments are performed with dimethyl methylphosphonate (DMMP) added to the oxidizer stream of methane-air

Evaluating smoldering behavior of fire-blocking barrier fabrics

January 29, 2015
Author(s)
Shonali Nazare, William M. Pitts, Szabolcs Matko, Rick D. Davis
This study reports on the smoldering propensity of commercially available barrier fabrics (BFs) in a small-scale mock-up configuration. Most BFs are smolder resistant when tested alone over a standard flexible polyurethane foam (FPUF). However, when

Evaluating Smoldering Behavior of Fire-Blocking Barrier Fabrics

January 29, 2015
Author(s)
Shonali Nazare, William M. Pitts, Szabolcs Matko, Rick Davis
This study reports on the smoldering propensity of commercially available barrier fabrics (BFs) in a small-scale upholstered seating mock-up configuration. Most commercially available BFs are smolder resistant when tested alone over a standard flexible

HVACR Editorial for IAQ 2013 Special Issue

January 23, 2015
Author(s)
Hal Levin, Steven Emmerich
The papers in this issue were selected from presentations made at the ASHRAE IAQ 2013: Environmental Health in Low Energy Buildings conference held in Vancouver Canada in October 2013. The conference was held specifically to review the state of knowledge

Effect of Installation Faults on Air-to-Air Heat Pump Performance

January 20, 2015
Author(s)
Piotr A. Domanski
Numerous studies and surveys indicate that typically-installed HVAC equipment operate inefficiently and waste considerable energy due to different installation errors (faults) such as improper refrigerant charge, incorrect airflow, oversized equipment

Monitoring Techniques for the Net-Zero Energy Residential Test Facility

December 31, 2014
Author(s)
Mark W. Davis, William M. Healy, Matthew Boyd, Lisa Ng, William V. Payne, Harrison Skye, Tania Ullah
NIST has constructed a Net-Zero Energy Residential Test Facility that will be used as a testbed for investigating the measurement science related to systems, components, and operations that will lead to homes that generate as much energy over a course of a

Behavior of Unrestrained and Restrained Steel Columns Adjacent to Localized Fire

December 12, 2014
Author(s)
Chao Zhang, John L. Gross, Therese P. McAllister, Guo-Qiang Li
Steel columns may be exposed to thermal radiation from localized burning of a fire source nearby. Current structural fire design methods are based on uniform heating and, therefore, uniform temperature conditions, and no practicable methods are provided to
