Honolulu benchmarking compliance, filed for you
The Honolulu Better Buildings Benchmarking Program (Ordinance 22-17) requires covered buildings to report energy and water use every year. We gather the data, check it, and file it — usually within a week.
Who’s covered
Commercial and multifamily buildings of 25,000 sq ft or more (since 2025) and city buildings of 10,000 sq ft or more.
Annual deadline
June 30 for the previous calendar year.
Verification
No routine third-party verification — but the program runs its own data checks, so accuracy still matters.
Penalties
A civil fine of up to $1,000 plus $100 per day, capped at $5,000 per building per year.
What to report
All energy and water used by the whole building — including tenant spaces — for January 1 to December 31:
- Electricity — every meter serving the building
- Natural gas
- District steam, hot or chilled water, if you have it
- Delivered fuels (oil, diesel, propane) — all delivery receipts for the year
- On-site solar production, if any
- Water — whole-building water use
Leave out backup generator fuel. Note any meters added or removed during the year.
Good to know
- Honolulu’s program is part of the City and County’s Climate Action Plan.
What we’ll need from you
- Building address, plus any utility service addresses that differ from it
- Gross floor area for the whole building and each use (office, retail, residential…), number of units and year built
- Your Honolulu Building ID (we can look it up)
- Utility data for the full calendar year, January 1 – December 31 (usually 13 months of bills)
- If tenants pay their own utilities: whole-building (aggregated) data from the utility, or signed tenant authorization forms
- Access to your ENERGY STAR Portfolio Manager account, if you have one
- Any notice or letter you received about this law
