Energy Benchmarking

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

Building benchmarking is measuring the 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 the relative energy, water and waste.


Ordinance 22-17 (formerly Bill 22), was signed into law by Mayor Blangiardi July 20, 2022 to establish a Better Buildings Benchmarking Program. The program will require large commercial and multifamily buildings on Oʻahu to benchmark and report their energy and water usage annually. The first annual reporting deadline begins in June of 2023 for buildings 100,000 square feet and larger, and then in June 2024 and 2025 for buildings 50,000 and 25,000 square feet and above, respectively. The Office of Climate Change, Sustainability and Resiliency will offer information, trainings, and guidance for building owners and property managers later this year and in lead up to these deadlines.
