Cindy Regnier, P.E., P.Eng., LEED AP is Technical Leader for Commercial Building Systems at Lawrence Berkeley National Lab in the U.S., and Executive Manager for FLEXLAB®, the U.S. Department of Energy’s newest building technologies testing facility – the Facility for Low Energy Experiments in Buildings. FLEXLAB is Berkeley Lab’s series of experimental testbeds focused on RD&D of integrated systems and grid enabled controls. She also manages several research projects focused on deployment of low energy systems and technologies. These include the development of integrated systems incentive programs for utilities, and 2030 District scale solutions focused on small commercial, working with a number of U.S. cities. Prior to joining LBNL in 2009, she spent 13+ years on design of innovative, integrated HVAC systems, including AIA COTE Top 10, LEED Platinum buildings, and a 200,000sf carbon neutral science museum. Her Bachelor’s degree is in Mathematics and Mechanical Engineering from Queen’s University, Canada, and she holds professional engineering licenses in California and Ontario, Canada.
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.
