The 2020 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through four separate lenses
Building products contain chemical compounds, such as volatile organic compounds, which can be emitted into indoor air and result in human exposures in the indoor environment. The emission rate, commonly measured in environmental chambers, is a key

This paper describes a modular mechanistic framework for predicting chemical emission from indoor sources, partitioning among indoor compartments and exposure to humans present in the indoor environment focusing on semi-volatile organic compounds (SVOCs)
The NIST Instrumented Charpy Test Suite is a set of standalone programs intended to allow anyone with appropriate hardware to perform and analyze instrumented Charpy impact tests. The software is provided in both raw code and executable formats with an

Premise plumbing systems provide key building services and exist in the context of a range of performance goals related to building energy efficiency, water conservation, reduced environmental impacts, and occupant health and comfort. Pressures to improve
Thermal conductivity measurements at and near room temperature are presented as the basis for certified values of thermal conductivity for SRM 1450e, Fibrous Glass Board. The meas-urements have been conducted in accordance with a randomized full factorial

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. The 250 m2 two-story
The National Institute of Standards and Technology (NIST) has previously demonstrated that, despite assumptions to the contrary, typical modern commercial building envelopes are not particularly airtight, resulting in significant energy costs. It has also
