Bio
Dr. Tianzhen Hong is a Senior Scientist and Principal Investigator 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, and 81. He was co-Operating Agent of Annex 66 and co-lead of Subtask 3 of Annex 79. His building energy software CBES won the 2019 R&D 100 Award and CityBES won the 2022 R&D 100 Award. He is an IBPSA Fellow, an ASHRAE Fellow, and a Highly Cited Researcher 2021. He received B.Eng. and Ph.D. in HVACR, and B.Sc. in Applied Mathematics from Tsinghua University, China.

For outstanding planning and execution of the 2023 BTUS Strategic Retreat
2022 R&D 100 Award: City Buildings, Energy, and Sustainability (CityBES) Web Tool for Climate Change Strategies - August 22nd 2022
Buildings generate 39% of global CO2 emissions, but evaluating and prioritizing cost-effective technical solutions for individual buildings at city scale poses a significant challenge for city stakeholders. CityBES is a free, powerful modeling and analysis tool that enables quick and quantitative assessments of actionable recommendations for decarbonizing buildings and improving their thermal resilience against extreme weather at the urban scale. CityBES builds upon open city datasets, international data standards, the powerful EnergyPlus simulation engine, a library of mitigation and adaptation measures, and 3D-GIS visualization to inform decision making on city buildings, energy, and sustainability.
2019 R&D 100 Award: Commercial Building Energy Saver - October 30th 2019
The Commercial Building Energy Saver (CBES), a software toolkit that enables equitable access to building deep retrofit and zero-net energy strategies for these buildings, won a 2019 R&D 100 Award in the software/services category.
The development team includes Berkeley Lab researchers Sang Hoon Lee, Xuan Luo, Kaiyu Sun, Tianzhen Hong, Cynthia Regnier, Mary Ann Piette (all pictured left to right), Yixing Chen, Rongpeng Zhang, Sarah C. Taylor-Lange, and Philip Price. The project was supported by the California Energy Commission and the Department of Energy.
