In this paper, we describe and demonstrate a graphical approach to illustrating the indoor air quality (IAQ) performance of high-performing buildings. We start by describing previous efforts to establish IAQ and indoor environmental quality (IEQ) metrics

Finite-element (FE) analysis was used to compare the high-temperature responses of steel columns with two different stressstrain models: the Eurocode 3 model and the model proposed by National Institute of Standards and Technology (NIST). The comparisons
On February 27, 2011, three fires began in the outskirts of Amarillo, Texas, two of which destroyed or damaged buildings in multiple housing developments. The National Institute of Standards and Technology (NIST), as part of its Disaster and Failure

Building modelers need simulation tools capable of simultaneously considering building energy use, airflow and indoor air quality (IAQ) to design and evaluate the ability of buildings and their systems to meet todays demanding energy efficiency and IAQ
Firebrand production from real-scale building components under well-controlled laboratory conditions was investigated. Re-entrant corner assemblies were ignited and during the combustion process, firebrands were collected to determine the size/mass

On April 20-21, 2015, NIST hosted a workshop that, through measurement science, enabled the owners of stationary sources (primarily the electric power industry) and their regulatory agencies (federal and state) to better characterize greenhouse gas (GHG)
As described by Reinhardt and co-workers [1], overpressure in the FAA Aerosol Can Test (FAA-ACT) has been observed for the halon replacements HFC-125, Novec 1230, and 2-BTP when added at sub-inerting concentrations. Work by Linteris and co-workers [2-5]

The newly-constructed National Fire Research Laboratory (NFRL) at the National Institute of Standards and Technology (NIST) provides an opportunity for the structural fire research community to undertake experimental research here-to-for not possible. This
The role of the interphase on mechanical performance of glassy polymer/single-walled carbon nanotube composites has been investigated by finite element (FE) method. The matrix and the interphase are modeled using continuum elements and the nanotube is
Recent research into Planetary Boundary Layer (PBL) flows accounts for the difference between �neutral� and �conventionally neutral� flows. Of interest in structural engineering are �conventionally neutral� PBL flows, that is, flows affected by transport
This note establishes a method to analyze wind pressure data on cladding and components of low-rise buildings using the National Institute of Standards and Technology-University of Western Ontario (NIST-UWO) database. The aerodynamic pressures induced on a

This supplement to the CFAST Technical Reference Guide provides details of the software development process for CFAST and accompanying experimental evaluation of the model. It is based in part on the Standard Guide for Evaluating the Predictive Capability
The purpose of this document is to describe the policies and procedures for developing and maintaining CFAST. Such a document is commonly referred to as a {\em Configuration Management Plan}. Description of the theoretical basis of the model, instructions

Building energy analysis tools are available in many forms that provide the ability to address a broad spectrum of energy-related issues in various combinations. Often these tools operate in isolation from one another, making it difficult to evaluate the
A Net-Zero Energy Residential Test Facility (NZERTF) has been constructed at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland to demonstrate that a home similar in size, aesthetics, and amenities to those in the

International and domestic operating experience involving High Energy Arc Faults (HEAF) in Nuclear Power Plant (NPP) electrical power systems have demonstrated the potential to cause extensive damage to electrical components and distribution systems along
Large outdoor fires are a problem in Japan and the USA. In order to prevent losing structures to large outdoor fires, it is important to understand the vulnerabilities of structures to firebrand showers and then, strengthen structures to these exposures
Firebrands have been known to be a significant cause of structure ignition in large outdoor fires, such as Wildland-Urban Interface (WUI) fires, large international problem, and urban fires, common in Japan. Sparse data exist with regard to firebrand
A dimensional analysis on firebrand penetration through a mesh screen was carried out to provide a framework to correlate a limited set of experimental data previously reported by Manzello et al. (2011). Two dimensionless variables were obtained. The
