The Construction and Building Subcommittee of the National Science and Technology Council is developing baseline measures of current construction industry practices and measures of current construction industry practices and measures of progress with
The objective of this guide is to inform applicants of the procedure to become FEMP-Qualified LCC Instructors. FEMP-Qualified Instructors are entitled to teach life-cycle costing (LCC) workshops similar to those conducted by NIST as part of the Federal
The goal of the 1997 ASHRAE/NIST Refrigerants Conference was to review available air-conditioning and refrigeration options in response to ozone depletion, global warming, and technology advances. The two-day program consisted of 16 invited comprehensive
Detailed measurements of the centerline mixing behavior in the near field of varible-density jets were performed. Real-time measurements of jet fluid concentration for a propane jet and a methane jet issuing into still air were made utilizing Rayleigh

A review of the structural performance of single-family, wood-frame houses is presented. The performance of these structures in selected earthquakes and hurricanes is summarized. In general, wood-frame houses performed well with relatively few instances of
The effect of supply airflow rate on the thermal conditions in a high-accuracy temperature controlled laboratory space was investigated using the NIST/BFRL Temperature Control Module. Detailed measurements were conducted of air and surface temperatures
Prior work has shown that thin filament pyrometry (TFP) is a powerful approach for making highly precise, spatially and temporally resolved line measurements of temperature in time-varying laminar diffusion flames. The technique has been previously used to
An apparatus was developed for testing the extinction efficiency of a solid powder in a coflowing non-premixed flame. Extinction measurements were performed by adding agent quasistatically to the oxidizer stream until flame extinction was observed. The
As part of ongoing National Institute of Standards and Technology research on the development of a new generation of standard provisions for wind loads, we present results of a pilot project on the knowledge-based estimation of wind-induced bending moments
Spills of flammable liquids, particularly gasoline, pose a significant fire hazard subsequent to a motor vehicle crash. Various considerations pertaining to making quantitative estimates of the level of hazard are discussed here. These include preliminary
In recent years, the use of fiber-reinforced polymer composites in civil infrastructure has been promoted as a solution to the deterioration of bridges, buildings, and other structures composed of traditional materials, such as steel, concrete, and wood

The structure and soot properties of round, soot-emitting, nonbuoyant, laminar jet diffusion flames are described, based on long-duration (175-230-s) experiments at microgravity carried out on orbit in the Space Shuttle Columbia. Experimental conditions
The purpose of this report is threefold. First, it describes how Data Envelopment Analysis (DEA) may be applied to assist the Manufacturing Extension Partnership (MEP) Program and its network of Manufacturing Extension Centers (MECs) in assessing
Fiber-reinforced polymer composites are increasingly used in offshore and civil engineering structures. In these applications, composite materials are often exposed to aqueous environments. This study investigated the role of the polymer/substrate
This publication is the Proceedings of the 30th Joint Meeting of the U.S..-Japan on Wind and Seismic Effects. The meeting was held at the National Institute of Standards and Technology, Gaithersburg, MD during 12-15 May 1998. The Proceedings include the
The Phillip Burton Federal Building and U.S. Courthouse located at 450 Golden Gate Avenue in San Francisco was selected as the site for the world's first large-scale commercial demonstration of the BACnet standard. BACnet is a standard communication
This section reports on two studies conducted at NIST on the suppression of wood crib fires and tire fires. An overview of previous research on the use of water based fire suppression agents on wood cribs and tires is provided. A burning pile of rubble or
***EACH PAPER IS TREATED LIKE A SEPARATE DOCUMENT AND MAY BE VIEWED AND/OR DOWNLOADED THAT WAY*** The Building and Fire Research Laboratory (BFRL) of the National Institute of Standards and Technology (NIST), under the sponsorship of the United States Fire
Water uses several different mechanisms to suppress and extinguish fires: fuel cooling, flame cooling, oxygen displacement and reduction of radiation feedback to the fuel. Laboratory experiments were conducted to determine which of these mechanisms play
The Building and Fire Research Laboratory (BFRL) of the National Institute of Standards and Technology (NIST), under the sponsorship of the United States Fire Administration (USFA), has conducted a series of experiments to demonstrate the suppression
The attention of wind engineers and extreme value climatologists has been focused in the last few decades on estimates of basic windspeeds, that is, wind speeds with 50 year or 100 year mean recurrence intervals (MRIs). Recently, however, efforts have been
This note describes a method for calculating conductive heat transfer between connected compartments in a zone fire model. The conduction problem is solved by dividing a compartment into six partitions corresponding to the floor and ceiling and the front
Potential improvements of the Coefficient of Performance (COP) were investigated for R-407C at cooling and heating conditions of a residential heat pump. The study used CYCLE-11, a semi-theoretical vapor-compression cycle model, which was upgraded to
NIST's Building and fire Research Laboratory (BFRL), one of NIST's seven Laboratories, enhances the competitivness of U.S. industry and public safety rhgough performance prediction and measurement technologies and technical advances that improve the life
