Better Buildings Benchmarking

What is Benchmarking and Ordinance 22-17?

Building benchmarking is the process of measuring a building’s consumption of energy and water over time. Regularly benchmarking allows building owners and managers to track one of their largest ongoing expenses (i.e., utility bills), understand their building’s performance relative to similar buildings, and identify opportunities to improve efficiency and eliminate waste. Benchmarking is the first step to managing and optimizing building performance and lowering costs.

The City’s Climate Action Plan identified the establishment of a community-wide benchmarking program as an important step in reaching net negative emissions by 2045. Currently, the building sector accounts for roughly one-third of Oʻahu’s total greenhouse gas emissions. This benchmarking program is expected to reduce the electricity consumption of large buildings by nearly 7% by 2030 and help curb greenhouse emissions on the island.

Ordinance 22-17 was signed into law by Mayor Blangiardi on July 20, 2022 to establish a Better Buildings Benchmarking Program. The program will require all large commercial and multi-family buildings to benchmark and report their whole-building electricity, gas, and water usage annually. Buildings 100,000 square feet or larger were the first covered properties to report by June 30, 2023, and buildings 50,000 square feet or larger began reporting June 30, 2024 (extended to September 30, 2024). Buildings 25,000 square feet or larger must begin reporting by June 30, 2025.
