In support of the U.S. Department of Energy's Building Technologies Office, researchers at PNNL usher in new ideas and technologies to improve the efficiency of commercial and residential buildings and enable national decarbonization aims. These experts advance lighting technology, building controls, and diagnostics, help make appliances more efficient, influence home and building construction, and facilitate workforce development. Along with improved efficiency in buildings, PNNL's advances help make sure that occupants remain productive and comfortable.

PNNL solutions range from clever, inexpensive fixes that harvest substantial energy savings to data-driven technologies that seamlessly coordinate a building’s energy use with the grid. PNNL’s influence is present in every building constructed in the United States since 1995.
