Indoor amenities that improve consumer health and productivity—such as heating, cooling, hot water, and refrigeration—can be satisfied while consuming less energy through advances in building equipment. Since the 1970s, ORNL has executed numerous equipment technology research and development collaborations with industry and university partners. Through use of extensive experimental facilities, advanced hardware based design models, and incorporation of emerging materials, our research has helped industry launch some of the most energy-efficient building equipment technologies on the market today.
