Building 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. Hawaiʻi Gas is committed to supporting Honolulu City Council Ordinance 22-17,also known as Better Buildings Benchmarking, which was signed into law by Mayor Rick Blangiardi in July 2022.
Who must participate?
The program will require all large commercial and multi-family buildings to benchmark and report their energy and water usage annually. Buildings 100,000 square feet or larger were the first covered properties to report by June 30, 2023. Buildings 50,000 square feet or larger must report by June 30, 2024, and buildings 25,000 square feet or larger by June 30, 2025. To comply, your building’s detailed property information and a year’s worth of the previous year’s calendar data for electric, gas, and water usage, must be submitted on the free EPA ENERGY STAR Portfolio Manager (ESPM) account. For more information regarding the program requirements, please see the City's website.
How to request gas consumption
If you are the property owner or an individual authorized to act on behalf of the property owner, of a building with fewer than four metered accounts for commercial buildings or six metered accounts for multifamily buildings, you must be an authorized party on the account (please see below for a description of an authorized party or how to become an authorized party) to receive individual gas consumption data. To request gas consumption data, please fill out a request form by clicking the Submit Request button below. A Hawaiʻi Gas customer service representative will respond to you within 3-5 business days.
For buildings with four or more metered accounts for commercial buildings, or six or more metered accounts for multifamily buildings, Hawaiʻi Gas will combine the yearly gas consumption data of all metered-accounts into a single file for the entire building, such that individual metered-account gas usage data is no longer identifiable. This is done to protect the privacy and anonymity of each individually metered account and allowed under the requirements of the program. See Ordinance22-17 for definitions of “owner” and “covered property.” You must provide each individual account number for the service address.
