Dr. Ronnen Levinson is a Staff Scientist and Leader of the Heat Island Group at Lawrence Berkeley National Laboratory (LBNL) in Berkeley, California. Within his research portfolio he develops cool roof, wall, and pavement materials; improves methods for the measurement of solar reflectance; and quantifies the energy and environmental benefits of cool surfaces. He serves on the boards and technical committees of the Cool Roof Rating Council and the Global Cool Cities Alliance, and advises policymakers, code officials, utilities, and building rating programs about cool surfaces. He holds a B.S. in engineering physics from Cornell University and an M.S. and a Ph.D. in mechanical engineering from the University of California at Berkeley. He has authored or co-authored over 80 publications, and serves on the editorial boards of Energy & Buildings and Advances in Building Energy Research. He received the 2016 Marty Hastings Award for outstanding contribitions to the Cool Roof Rating Council, and a 2016 R&D 100 Award for invention of the Cool Roof Time Machine.
