Dr. Tianzhen Hong is a Senior Scientist leading research on technologies, data, methods, computing, occupant behavior, and policy for design and operation of low energy buildings and sustainable urban systems. He is leading the EnergyPlus development at LBNL. He established and chairs the ASHRAE Technical Committee 7.10 Occupant behavior in building design and operation. He actively contributed to international collaborations such as the 10-year U.S.-China Clean Energy Research Center on Building Energy Efficiency, IEA EBC Annex 53, 66, 79, and 81. He was co-Operating Agent of Annex 66 and co-lead of Subtask 3 of Annex 79. He led the development of two building energy software: CBES and CityBES winning an R&D 100 Award in 2019 and 2022, respectively. He is an IBPSA Fellow, an ASHRAE Fellow, and a Highly Cited Researcher since 2021. He received B.Eng. and Ph.D. in HVACR, and B.Sc. in Applied Mathematics from Tsinghua University, China.
