Dr. Xiaobing Liu is a Senior R&D Staff in the Energy Science and Technology Directorate at Oak Ridge National Laboratory (ORNL). He currently leads the Thermal Energy Storage Group at ORNL. Dr. Liu has 20 years of experience and expertise in developing technologies for saving energy and reducing carbon emissions in buildings. He has led many R&D projects and developed several software tools and prototypes of new HVAC equipment, including software tools to facilitate the design and techno-economic analysis of ground source heat pump (GSHP) systems, low-costs ground heat exchangers, thermal energy storage integrated with heat pumps, building envelopes integrated with phase change materials, high-density energy storage and dehumidification systems using sorption technologies. He has published more than 30 journal and over 100 conference articles and reports. Dr. Liu serves as the research committee chair of the International Ground Source Heat Pump Association (IGSHPA). He also served as the research subcommittee chair at the American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE) TC 6.8 for Geothermal Energy Utilization and Energy Recovery. Dr. Liu is a co-recipient of the Ritter Von Rittinger Award from the International Energy Agency (IEA) Heat Pump Center in 2017. He also received the Distinguished Service Award from ASHRAE in 2020, the R&D 100 Award (group) in 2022, and the Best paper/presentation Award from various conferences. Dr. Liu graduated from Oklahoma State University (OSU) with a Ph.D. degree in 2005. He joined ClimateMaster as the Systems Engineering Manager after graduating from OSU. In this position, Dr. Liu developed modules for the eQUEST program to simulate GSHP systems and participated in the design of more than 30 GSHP systems worldwide.
