Apparent combustion enhancement by some halon replacement fire suppressants (proposed for use in aircraft cargo bays) has been observed in full-scale, constant-volume tests at the FAA. In order to explore the phenomena, laboratory-scale constant-volume
As building envelope performance and HVAC equipment efficiencies are increasingly improved to reduce building energy use, a greater percentage of the total energy loss of a building can occur through envelope leakage. Although the energy impacts of

A Net-Zero Energy Residential Test Facility has been constructed at the National Institute of Standards and Technology in Gaithersburg, Maryland. The facility is being used to demonstrate that a home similar in size, aesthetics, and amenities to those in

In this paper, we review how indoor air quality (IAQ) has been addressed in case studies of high-performing buildings (HPBs), specifically the case studies described in ASHRAEs High Performing Buildings magazine. We find that nearly all of the reported
NISTs Engineering Laboratory (EL-NIST) hosted Operation Tomodachi Fire Research on March 16-18, 2015 in Gaithersburg, MD USA. Tomodachi means friendship in Japanese. This workshop was organized by Dr. Samuel L. Manzello of EL-NIST in partnership with
Real-time electricity monitoring in residences is a growing market, with a number of systems being commercialized that provide feedback to occupants on electrical power and energy consumption. These systems are also useful for research purposes, by better

Homeowners and builders have increasingly strived to build low energy use and environmentally friendly homes. As materials and equipment have improved, energy reduction as a goal has increasingly been replaced with the goal of net-zero energy use. But the

The National Institute of Standards and Technology (NIST) through American Recovery and Reinvestment Act of 2009 (ARRA) funding built the Net Zero Residential Test Facility (NZERTF) as a NIST laboratory in the form of a typical residence to measure
A natural gas burner has been used as a precise and accurate source for generating large quantities of carbon dioxide (CO2) to evaluate emissions measurements at near-industrial scale. Two methods for determining carbon dioxide emissions from stationary
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

Numerical simulations of cup-burner flames in normal Earth gravity have been performed to study the combustion inhibition and unwanted enhancement by fire-extinguishing agents CF3Br (Halon 1301) and some potential replacements (C2HF5, C2HF3Cl2, and
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
Flexible polyurethane foam (PUF) is coated by layer-by-layer (LbL) assembly using branched polyethyleneimine (BPEI), poly(acrylic acid) (PAA), and two different charged nanoparticles, such as sodium montmorillonite (Na-MMT) and layered double hydroxide
This report documents the effort launched by the National Institute of Standards and Technology (NIST) to develop, organize, and convene a workshop on sustainability to promote the adoption and use of sustainable construction and manufacturing and guide

Firefighters working inside a burning structure often experience burns related to hot water vapor inside firefighter protective clothing (FFPC). For these burns to occur, the water vapor is heated by the high temperatures outside the FFPC and it diffuses
It is widely recognized that residential and commercial heat pump equipment experience significant "in-field" performance loss (i.e., capacity and efficiency) depending on how the components are sized, matched, installed, and subsequently field-maintained
Primary focus of this paper is to review existing test methods that quantify steam burn injuries and to compare bench-scale test methods that use pre-wetted samples as opposed to external steam exposures to evaluate heat and moisture transfer in protective
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

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
