Sixteen reference commercial buildings were defined by the U.S. Department of Energy (DOE) and created as EnergyPlus input files. They were developed for use in assessing new technologies and supporting the development of energy codes. Infiltration rates
The accomplishments of the project are summarized in three published studies, which follow this abstract and constitute this final report. The studies use layer by layer assembly methods to investigate material flammability. In the first study, entitled,
LoopDA 3.0 is an update to version 1.0 of the natural ventlation design tool developed by the Natural Institute of Standards and Technology. This software tool can be utilized to determine the size of natural ventilation openings necessary to provide a

This report documents a set of 9 full scale ISO 9705 room under-ventilated compartment fire experiments for the purpose of guiding the development of the National Institute of Standards and Technology (NIST) computer fire model - Fire Dynamics Simulator
The enterprise integration-style interfaces and information models in the Organization for the Advancement of Structured Information Systems (OASIS) collaborative energy standards are designed to address information exchange across the smart grid. This
Construction of sustainable, energy efficient buildings, infrastructure and transportation systems is a worthwhile and necessary goal to address critical worldwide environmental and energy concerns. However, as societies move toward this goal, it is the
Building occupants, who have been instructed to use elevators for evacuation, and have subsequently congregated within the elevator lobby for eventual evacuation, are presented with an uncertain and potentially intimidating situation. For example, waiting
This report describes the results of calculations using the NIST Fire Dynamics Simulator (FDS) performed to provide insight on the thermal conditions that may have occurred during a wind-driven fire in a one-story ranch house on April 12, 2009 in Houston
The National Institute of Standards and Technology (NIST) is conducting a multi-year study, with the support of the National Institute of Justice (NIJ) and the NIST Office of Law Enforcement Standards (OLES), to examine the repeatability of burn patterns
The General Services Administration (GSA) established the National 3D-4D-BIM (Three dimensional- Four Dimensional Building Information Model) Program in 2003. A part of the program involves 3D imaging, and the National Institute of Standards Technology
This is an in-progress presentation of a plan whose goal is to develop and demonstrate, by 2004, environmentally-friendly, user-safe processes, techniques, and fluids that meet the operational fire extinguishment and explosion suppression requirements

This report summarizes part of the work of IEA-ECBCS Annex 47 Cost-Effective Commissioning of Existing and Low Energy Buildings. It is based on the research findings from the participating countries. The publication is an official Annex report. Report 1,
This report summarizes FDS development and support activities performed during the three year grant period of 70NANB8H8161. A brief overview of the major and minor accomplishments are provided below. More detailed discussions follow in the remainder of

National Institute of Standards and Technology (NIST), conducted experiments which demonstrated a range of realistic thermal exposures and environmental conditions that firefighters could be exposed to. Self-contained breathing apparatus (SCBA) facepieces
Steel structures when exposed to fire develop significant fire induced forces and deformations, and these effects are to be properly accounted for in evaluating realistic response of structural systems. The current design methodologies are based on

Reports by the National Institute of Standards and Technology (Gann 2005), the UK-based Institution of Structural Engineers (IStructE) (Roberts 2002), and a national workshop on state-of-the-art of structural-fire engineering (Kodur et al. 2007) all have
Hydrogen as an energy carrier has received much attention in recent years as a result of a confluence of economic, environmental, and political pressures on the continued use of fossil fuels. The benefits of using hydrogen fuel over fossil fuel products
This report documents the development and testing of the LES (Large Eddy Simulator) version of the WRF (Weather Research and Forecasting) model coupled with SFIRE, the wildland surface fire module, to simulate wildland fires. The relevance of this work to
This paper quantifies the influence of Al2O3 nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a Turbo-BII-HP boiling surface. An Al2O3 nanolubricant (a lubricant containing dispersed nano-size particles) was made by suspending
