Benchmarking for Commercial and Multi-Family Buildings on Oahu

Hawaiʻi Gas is committed to supporting Ordinance 22-17, also known as Better Buildings Benchmarking, that was signed into law by Mayor Blangiardi. This involves responding to requests from building owners on Oahu to provide aggregated whole-building energy consumption data so that they can, in turn, report on their utility usage to the City.

Better Buildings Benchmarking is the process of measuring a building's consumption of energy and water over time. Regular benchmarking allows building owners and tenants to understand their building's energy and water use and identify opportunities to cut waste and save money.

If you are a property owner or a manager needing gas consumption data, please fill out a request form by clicking the Submit Request button below. A customer service representative will get back to you within 3-5 days.
