Robert Hart performs research and model development of energy-efficient windows and window attachments within the Windows and Envelope Materials Group. His recent work includes the development and experimental analysis of highly insulating "super windows", shading systems, and vacuum glazing. He holds a B.S. in Mechanical Engineering from Cal Poly San Luis Obispo and a M.S. in Mechanical Engineering from Stanford University with concentrations in heat transfer and fluid dynamics. He is a registered Professional Engineer in the state of California, and a LEED AP.
