The purpose of this article is to introduce a conceptual model of human behaviour in fire. This model is constructed based upon a theoretical framework of individual decision-making and response to emergencies, and from this foundation, is populated with
The Net Zero Energy Residential Test Facility (NZERTF) was constructed at the National Institute of Standards and Technology (NIST) to support the development and adoption of cost-effective net zero energy designs and technologies. Key design objectives

Fire behavior of five barrier fabrics has been evaluated both, as an individual component and as a part of composite samples, using different test methods. The quantitative component test methods selected to characterize fire behavior of barrier fabrics

This study is meant to be applied to residential, unitary, air-source, single-speed, vapor compression air-conditioning systems with nominal cooling capacities less than 19 kW (65,000 Btuh-1 or 5.4 tons). In this research, a method for self-training FDD
This manual describes the computer program CONTAM version 3.2 developed by NIST. CONTAM is a multizone indoor air quality and ventilation analysis program designed to help you determine: airflow rates and pressures infiltration, exfiltration, and room-to

The paper highlights key components of a fire model validation study conducted by the U.S. Nuclear Regulatory Commission and the Electric Power Research Institute. These include the selection of fire phenomena of interest to nuclear power plant safety, the

Rheological measurements are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating [1]. Usually, an angular velocity is imposed on the fluid (through the rotating

We explore the possibilities for low-GWP refrigerants through two approaches. First, we explore the performance of hypothetical refrigerants to define the limits of what is allowed by thermodynamics. In the second approach, we apply property estimation

The study analyzed the effect of common installation faults on the cooling performance of a residential, split air conditioner installed in a single-family, slab-on-grade house. We considered five climatic regions in the United States from hot/humid to
In the USA, wind loads for building design are specified in a publication of the American Society of Civil Engineers (ASCE 7). The current version, ASCE 7-10, relies on wind tunnel tests that date back 30 to 50 years. In recent decades, many more test

A series of experiments were conducted to examine ignition of wood fencing assemblies subjected to continuous, wind-driven firebrand showers. Specifically, Western Red Cedar and Redwood fencing assemblies were exposed to continuous, wind-driven firebrand

The National Institute of Standards and Technology (NIST) constructed a Net Zero Energy Residential Test Facility (NZERTF) to support the development and adoption of cost-effective NZE designs and technologies. Key design objectives include providing
NIST is developing a framework to define programs and strategies to increase community-based resilience in the face of a broad range of natural disasters and other extreme events. Many of these events will affect indoor environmental quality either through

This study seeks to develop an understanding of the effect of these common faults on the energy consumption of a heat pump installed in a single-family, slab-on-grade residential house. Through annual simulations of the house/heat pump system, the study
Current structural re design approaches are based on uniform heating conditions. Steel short columns in real buildings may be exposed to non-uniform heating conditions in accident res. This paper investigates numerically the behavior of steel short columns
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
