Buildings account for nearly a third of the world s energy use today, and this share is expected to rise along with population growth and levels of prosperity. In the United States, residential and commercial buildings consume about 40% of primary energy

Because of concerns about indoor air quality, there is growing awareness of the need to reduce the rate at which indoor materials and products emit volatile organic compounds (VOCs). To meet consumer demand for low emitting products, manufacturers are
Effects of sample surface free energy (s) and relative humidity (RH) of the tip-sample environment on image contrast and friction characteristics measured with lateral force microscopy (LFM) have been investigated. Samples having a wide range of surface
The benefits of energy conserving approaches in buildings are often not apparent to building occupants because of the insufficient feedback provided regarding energy consumption. A review of the literature suggests that energy feedback devices can provide

Graphene oxides are potentially a new class of nanomaterial to enhance multifunctional properties of polymers because of their remarkable thermal conductivity, mechanical strength, and more importantly, low cost. The graphene oxides, produced by
Building energy efficiency has become a top priority due to the recent energy price spikes and increasing concern regarding climate change. It is easier and less costly to increase energy efficiency in new buildings than in existing buildings, making new
An uncertainty analysis for steady-state thermal transmission properties determined by the National Institute of Standards and Technology (NIST) 1016 mm Guarded-Hot-Plate apparatus is presented for fibrous-glass blanket and expanded polystyrene board. The
We use a hedonic model to simultaneously estimate the effects of street trees on the sales price and the time on market of houses in Portland Oregon. On average, street trees add $7020 to sales price and reduce time on the market by 1.9 days. Extrapolating
The Outer Shell of the jacket and pants of the firefighter s protective clothing is constructed of a fabric that is commonly a blend of polyaramid, polybenzimidazole, and/or poly(melamine-formaldehyde) fibers. The Outer Shell contributes to the thermal and

The Innovative Fire Protection Workshop was held at the National Institute of Standards and Technology (NIST) on June 4 and 5, 2009. The 70 participants represented a broad range of stakeholder perspectives, including various non-profit, academic, industry
The relationship between AFM probe-sample adhesion force and relative humidity (RH) at five different levels of surface free energy (γs) of an organic self-assembled monolayer (SAM) has been investigated. Different γs levels were achieved by exposing a
There are many improvements needed in concrete, especially for use in renewal and expansion of the world's infrastructure, e.g. increased durability, decreased brittleness and increased tensile strength, and use of non-traditional materials like fly ash
The evacuation process is influenced by historical events. These can reflect previous incidents, training, and the routine use of the structure. These need to be considered during the design process as they will influence occupant behavior. In addition
An assessment of uncertainties for the National Institute of Standards and Technology (NIST) 1016 mm Guarded-Hot-Plate apparatus is presented. The uncertainties are reported in a format consistent with current NIST policy on the expression of measurement

The study sought to develop an understanding of the impact of commissioning common faults the energy consumption of an air-to-air heat pump installed in a single-family house. Through annual simulations of the house/heat pump system, the study found that
On February 19, 2009, the National Institute of Standards and Technology (NIST) held a Federal Workshop on Mass Notification Messages. Participants from 12 federal agencies attended to discuss issues surrounding warning the public, building occupants, and
Automatic sprinkler systems have been successfully used to protect industrial and commercial buildings and their occupants for more than 100 years. Historically the place which has offered the least amount of fire protection to occupants, was and still is
None was required. Here is the last paragraph of the introduction. In this chapter are examples of how we used HT to accelerate knowledge about polymer materials. The first case study describes the development and application of HT tools and methods to
Under the auspices of contract SB134109SE0612, The NIST contracted with Southwest Research Institute (SwRI) to perform a testing program designed to support NIST efforts on characterizing the behavior of hydrogen when released into enclosed spaces (e.g
The objective of this study was to compare the levels of hazard created by room fires in a dormitory building with and without automatic fire sprinklers in the room of fire origin. This report describes a series of experiments where fires were initiated in
This paper quantifies the influence of diamond nanoparticles on the pool boiling performance of R134a/polyolester mixtures on a roughened, horizontal, flat surface. Nanofluids are liquids that contain dispersed nano-size particles. A lubricant based

The General Services Administration (GSA) has been involved in 3D imaging since the early 2000s. Since 3D imaging was a relatively new technology at that time, GSA needed to develop and provide initial guidance to their project managers (PMs) on 3D imaging
Hydrogen presents several unusual fire hazards, including high leak propensity, ease of ignition, and invisible flames. This research concerns experiments, analysis, and computations to identify the hazards of leaks in hydrogen systems that could result in
