About National Renewable Energy Laboratory

The National Renewable Energy Laboratory (NREL) is the only national laboratory solely dedicated to advancing renewable energy and energy efficiency. As part of the U.S. Department of Energy's Small Business Vouchers Pilot, NREL will connect clean energy innovators across the country with top-notch scientists, engineers, and analysts, as well as world-class facilities for research focusing on energy consumption reduction and demand side management and interoperability.


NREL's Buildings Research Program develops cutting-edge technical solutions to improve the energy efficiency in both residential and commercial buildings including HVAC, water heating, building envelope, windows, solid-state lighting, sensors and controls, appliances (e.g., clothes washers and dryers), and building energy modeling. NREL researchers work with a variety of partners to conceive innovative ideas, develop concepts into prototypes, improve and integrate multiple technologies, engineer entire systems, and provide technical assistance and tools that span the energy sector.

NREL's buildings capabilities include the following:

  • Modeling and simulation
  • Whole-building energy performance
  • Market transformation strategies
  • Grid Integration
  • Prouduct development and/or integration
  • Measurement, data collection and analysis.


NREL provides industry, government, and university researchers with access to state-of-the-art and unique equipment for analyzing a wide spectrum of building energy efficiency technologies and innovations.

NREL facilities include:

Advanced Windows Testing Facility: This facility resides in NREL's Field Test Laboratory building and it tests emerging window technologies including highly efficient insulating glass units and window frames.

Energy Systems Integration Faciity (ESIF): The nation's premier facility capable of conducting integrated megawatt-scale research and development of the components and strategies needed to move clean energy technologies onto the electrical grid.

  • Smart Home and Building Systems: This lab features smart home test bays capable of evaluating a variety of household appliances and systems.
  • Thermal test Facility (TTF): A living laboratory that develops optimal solutions for managing energy flows within buildings and transportation systems.
