Longmont benchmarking compliance, filed for you
The Longmont Energy Benchmarking program (voluntary) requires covered buildings to report energy use every year. We gather the data, check it, and file it — usually within a week.
Who’s covered
Voluntary for commercial and industrial buildings of 20,000 sq ft or more. Buildings of 50,000+ sq ft must still report to the State of Colorado.
Annual deadline
No city deadline (voluntary) for the previous calendar year.
Verification
No routine third-party verification — but the program runs its own data checks, so accuracy still matters.
Penalties
None for the city program. The state program has its own penalties for 50,000+ sq ft buildings.
What to report
All energy 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
Leave out backup generator fuel. Note any meters added or removed during the year.
Good to know
- Participants share their ENERGY STAR score with Longmont Power & Communications.
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 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
