This report summarizes the results of the global meeting to develop the International R&D Roadmap for Fire Resistance of Structures (the Roadmap) held May 2122, 2014, in Gaithersburg, Maryland. The workshop was sponsored by the National Institute of
A key challenge in assessing the risks of low level contaminations following biological threat agent releases, and subsequent decontamination, is developing an understanding of and addressing the potential for airborne resuspension of agents that have

In 2013, fire departments in the United States responded to more than 480,000 structure fires. These fires resulted in approximately 2850 civilian fatalities, 14,000 injuries, and estimated property losses of $10 billion dollars. More than 30,000 fire
An experimental apparatus designed to study firefighter turnout gears exposed to a thermal environment was developed. The apparatus consisted of an elevated temperature flow loop with the ability to heat the air stream up to 200 ºC. The thermal and flow
Heating, ventilating, and air conditioning (HVAC) systems in buildings are designed to provide thermally comfortable conditions and to maintain acceptable indoor air quality (IAQ). At the same time, the operating costs of HVAC systems are often a large
This paper presents two models developed to describe the pre-evacuation period of the 2001 WTC Disaster. The first model is a conceptual model developed from performing a qualitative study of occupant behavior in response to the September 11, 2001 World

Advanced simulation methods are needed to precisely predict the complex behavior of structures exposed to natural fire conditions. Fire Dynamics Simulator (FDS) is a computational fluid dynamics (CFD) code, developed by NIST for fire related simulations
Beginning in 2010, the Foundation began a program to review the potential effectiveness of various technologies potentially capable of preventing cooking range top fires. A workshop conducted as part of that project considered the emergence of commercial
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the world. The 2007 Southern California Fire forced 300,000 people to evacuate, destroyed over one thousand structures, and
Wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires, have destroyed communities throughout the USA. The best way forward to address the WUI fire problem is hardening of structures [1]. Without standard laboratory

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

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
A new framework for a risk-informed performance-based approach to fire safety analysis and design has been proposed. It is structured around a paradigm in which the performance analysis is conducted relative to the performance of a building-occupant system
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

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

The Smoke Aerosol Measurement Experiment (SAME) has been conducted twice by NASA and provided the first real-time aerosol data in a spacecraft micro-gravity environment. Flight experiment results have recently been analyzed with respect to comparable
