Building performance standards in 2026: deadlines, penalties, and how to stay ahead
More than 40 US cities and states now require large buildings to benchmark energy use, and a growing number attach real penalties for missing emissions limits. Here is what is due, what it costs to miss it, and how to get the data ready.
For years, energy benchmarking was a disclosure exercise: measure your building, report the number, move on. That era is ending on both sides of the border. In Canada, Ontario, Québec and British Columbia already require large buildings to report, and the federal government is funding more provinces and cities to follow. In the United States, more than 40 cities and states have adopted benchmarking or building performance standards, many with penalties for missing emissions limits.
If you own or manage large commercial or multifamily buildings, the practical question is no longer whether you benchmark. It is whether your data is accurate enough to avoid a penalty and to defend the number if someone asks. We are a Canadian company, so we will start at home.
Start close to home: Canada
Ontario's Energy and Water Reporting and Benchmarking program requires commercial, institutional and multi-residential buildings of 50,000 sq ft and up to report energy and water use to the province each year by July 1, through ENERGY STAR Portfolio Manager. The City of Toronto layers its own bylaw on top and, from 2027, extends mandatory reporting down to buildings of just 10,000 sq ft, pulling in a large number of mid-size buildings for the first time. The City of Montréal goes further still: By-law 21-042 requires large buildings to report energy data by June 30 and now assigns each one a public GHG rating from AAA to F. Vancouver's greenhouse gas intensity limits phase in through 2027, with a $350 per tonne fee above the limit, though the city paused enforcement in May 2026 pending a review.
The federal direction reinforces it. ENERGY STAR Portfolio Manager was adapted for Canada by NRCan and already tracks tens of thousands of Canadian buildings, and Budget 2024 put $73.5 million behind helping provinces and cities stand up benchmarking, disclosure and building performance standards. The Canada Green Buildings Strategy treats mandatory standards as a provincial and municipal tool, so expect more Canadian jurisdictions to adopt them, not fewer. You can check the current rule for your province or city in a few seconds.
In the US, the penalties are real and specific
The exact rules vary by jurisdiction, but the direction is consistent: measure, report, and increasingly, perform. A sample of what non-compliance costs today:
| Jurisdiction | What it does | Penalty for missing |
|---|---|---|
| New York City (LL97) | Emissions caps on large buildings | $268 per tonne CO2 over the limit |
| Washington DC | Building energy performance standard | Up to $10 per sq ft of gross floor area |
| Seattle | Building performance standard | Around $10 per sq ft annually |
| Boston (BERDO) | Emissions limits | $1,000 per day for larger buildings |
| California (AB 802) | Benchmark + disclose (>50,000 sq ft) | Up to $2,000 per day |
| Colorado | 7% emissions cut by 2026, 20% by 2030 | 2026 targets now non-enforceable goals |
Sources for the table: Facilities Dive and Envigilance. Colorado's 2026 targets were made non-enforceable goals under a 2025 amendment, a reminder that these programs move quickly and are worth confirming against the current rule in each jurisdiction.
Most jurisdictions require reporting through ENERGY STAR Portfolio Manager, the EPA's benchmarking tool. That is helpful for consistency, but it also means the same whole-building energy data has to be assembled, cleaned and submitted against several different deadlines.
The real cost is the data work
The penalty headlines get attention, but for most teams the recurring cost is the data itself. The single biggest operational expense of benchmarking is staff time spent collecting bills, normalizing formats, entering consumption into Portfolio Manager and troubleshooting data-quality errors. For a portfolio of twenty buildings across five jurisdictions with different deadlines, that labor routinely exceeds $40,000 a year.
How to get ahead of it
The buildings that handle these standards calmly are the ones that treat energy data as a live dataset, not an annual scramble. In practice that means:
- Know your obligations by address. Requirements are set locally, so a national portfolio can face several different rules at once.
- Get whole-building data flowing automatically, from bills and, where available, utility data feeds, rather than re-keying it each spring.
- Validate the inputs before you submit. A wrong meter multiplier or a missing month quietly changes your reported intensity and your emissions.
- Track your gap to the limit through the year, so a compliance problem is a planning question in Q1, not a penalty in Q4.
MartinAI handles the first mile of that work: reading your bills across every commodity and layout, validating them, and producing the structured, whole-building energy record that benchmarking and emissions reporting depend on.
Frequently asked questions
What is a building performance standard?
A building performance standard, or BPS, requires owners to track and report a building's energy use and greenhouse gas emissions and, increasingly, to meet performance or emissions targets over time. Most programs use ENERGY STAR Portfolio Manager for reporting.
How many US jurisdictions have benchmarking or BPS laws?
As of 2026, more than 40 US cities and states have adopted energy benchmarking ordinances, building performance standards, or both, covering the majority of large commercial buildings.
What happens if a building misses its limit?
It depends on the jurisdiction. Penalties range from per-tonne charges on emissions above a cap (for example $268 per tonne under NYC Local Law 97) to daily fines and per-square-foot annual penalties elsewhere.

Energy use intensity (EUI), explained: the one number every building owner should track
EUI turns a building's messy energy history into a single, comparable number. Here is exactly how it is calculated, how it relates to the ENERGY STAR score, and why the data behind it is where most teams struggle.
From utility bills to a Scope 1 and 2 emissions inventory
Most of a building or company's Scope 1 and 2 emissions come straight from data already sitting on utility bills. Here is how the accounting works, what the 2026 disclosure rules ask for, and how to build the inventory from the bills you already receive.
