Mary Ann Piette, deputy of the Building Technologies Department at Lawrence Berkeley National Laboratory.Mary Ann is an energy geek we love. She develops and evaluates low-energy and demand response technologies for buildings. She specializes in commissioning, energy information systems, benchmarking and diagnostics. And she has written more than 100 papers on efficiency and demand response. In 2006, she received the Benner Award at the National Conference on Building Commissioning for contributions to making commissioning business as usual.
Researchers in the Building Technology & Urban Systems Division (BTUS) at Lawrence Berkeley National Laboratory develop data and technologies that increase energy efficiency and improve the health, safety and comfort of building occupants, in the United States and worldwide.
We work closely with industry partners, academics and government officials to achieve these goals, and share our research widely.
We are at the forefront of cutting-edge research that redefines building technology and explores all areas of urban systems.
We have been leaders for decades in developing energy-efficient windows, improving indoor air quality, coming up with new ideas to fix the nation's electricity grid, and so much more.
