Awards

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.
