Dr. Tianzhen Hong is a Senior Scientist, Principal Investigator, and Deputy Head of the Building Technologies Department. He leads the Urban Systems Group and a team with research on 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 Multidisciplinary Task Group on occupant behavior in buildings. 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, 80, and 81. He was co-Operating Agent of Annex 66 and co-lead of Subtask 3 of Annex 79. One of his software toolkit, CBES, won the 2019 R&D 100 Award. He is IBPSA Fellow and ASHRAE Fellow.
