AB 1103 Benchmarking California’s Buildings

AB 1103 requires commercial building owners to benchmark and disclose a building’s historical energy usage prior to selling, leasing or financing the entire building.

The statute requires energy consumption data to be collected from utility companies and entered into the Environmental Protection Agency’s ENERGY STAR Portfolio Manager system, which generates an energy efficiency rating for the building.

Buildings with high ratings (75 out of a 100 and up) that have had their data verified by a Professional Engineer (PE) can apply for an ENERGY STAR certification.  Buildings with ratings below 75 should consider implementing energy efficiency upgrades to reduce energy consumption.
