Evan Mills is a retired Senior Scientist in the Building Technology and Urban Systems Division, and has worked in the energy efficiency field since 1982. He previously led the Center for Building Science at LBNL. His core commercial-buildings expertise is in energy benchmarking, commissioning, high-tech buildings, risk management, and the efficiency business case. He is a frequent speaker to academic and industry audiences on buildings energy efficiency, author of over 300 publications, and member of the Intergovernmental Panel on Climate Change, which shared the 2007 Nobel Peace Prize. He is a recipient of an R&D 100 award for commercializing Home Energy Saver software in 2009. Mills holds a MS degree in Energy and Resources from U.C. Berkeley and a Ph.D. in Environmental and Energy Systems Studies from Lund University in Sweden.
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.
