If you can measure it, you can control it. If you can control it, you can manage it.

Building benchmarking is measuring energy and water use, and using that data to compare performance over time as well as compare to similar buildings. Benchmarking allows owners and occupants to understand their building systems and to make changes which lower operating costs and can improve occupant comfort and health.

Benchmarking is free using the industry-standard ENERGY STAR Portfolio Manager tool.

Once buildings are benchmarked, Hawaii Energy will direct you to our Clean Energy Allies to help with implementing retrofits and upgrades.

City & County of Honolulu Better Buildings Benchmarking program (Bill 22)

In 2022, the City and County of Honolulu established the Better Buildings Benchmarking Program, which requires large commercial and multifamily buildings on Oahu to benchmark and report their energy and water usage annually. Buildings 100,000 sq. ft. and larger were required to benchmark by June 30, 2023, followed by buildings above 50,000 sq. ft. (deadline June 2024) and 25,000 square feet (deadline June 2025).
