An official website of the United States government Here’s how you know Menu ENERGY Overview NIST develops the testing, measurements, and reference materials needed to ensure the quality of energy-related products and services and ensure fairness in the marketplace. FEATURED CONTENT Smart Grid program Net-Zero Energy Residential Test Facility Energy Topics Alternative energy Conventional energy Electric power / smart grid Fuels The Research PROJECTS & PROGRAMS Measuring the Performance of Net-Zero Energy Homes COMPLETED A Net-Zero Energy Residential Test Facility (NZERTF) has been constructed and extensively instrumented. The facility incorporates a high-performance envelope, a Reference Fluid Thermodynamic and Transport Properties Database (REFPROP) ONGOING The NIST REFPROP database provides the most accurate thermophysical property models for a variety of industrially important fluids and fluid mixtures, including Standard Reference Measurements ONGOING Property measurements of the very highest accuracies are important for developing the thermodynamic and transport property models for working fluids and View All Projects/Programs ADDITIONAL RESOURCES LINKS Publications Software News That House on the Hill: Bringing Measurement Science Home When people ask NIST employees what they do, we often rely on the somewhat nebulous term “measurement science.” To many in the technical community, NIST’s role in measurement science is clear because they are often surrounded by instruments that bear some sort of NIST-traceable calibration certificate.
