Building Performance Standards 101

For years, most building energy regulation stopped at disclosure, tell the city how much energy a building uses, and that was the end of the obligation. Building Performance Standards go further. They set an actual performance limit, an emissions cap or an energy use target, and attach real financial penalties when a building doesn't meet it. Over 40 U.S. cities are expected to have an active Building Performance Standard in place, and the list keeps growing at both the city and state level.

What Makes a BPS Different From Benchmarking

Benchmarking laws, the kind built around ENERGY STAR Portfolio Manager, require a building to measure and report its performance. A Building Performance Standard requires a building to actually meet a target, and it comes with an enforcement mechanism, typically a per ton or per square foot penalty, when it doesn't. Benchmarking is a reporting obligation. A BPS is a compliance obligation.

The Major U.S. Standards

New York City, Local Law 97. The most aggressive standard in the country, covering roughly 50,000 buildings over 25,000 square feet with emissions limits by occupancy type. Penalties run $268 per metric ton of carbon dioxide equivalent over the annual cap, assessed every year until a building comes into compliance. First compliance reports were filed in 2025, and a legal challenge to the law was dismissed by New York's highest court that same year.

Boston, BERDO 2.0. Covers buildings over 20,000 square feet, representing more than 60% of the city's total building emissions. Buildings that exceed their limit pay $234 per metric ton into the city's Equitable Emissions Investment Fund, and covered properties must also submit an individual emissions reduction plan showing a credible pathway to carbon neutrality by 2050.

Washington, D.C., BEPS. Structured differently, with penalty exposure calculated per square foot of gross floor area rather than per ton of emissions, reaching as much as $10 per square foot for a non compliant building, a meaningful number for any building of real size. The program's compliance timeline has faced proposed delays, a reminder that BPS schedules can shift even after a law is on the books.

Washington State, Clean Buildings Performance Standard. Applies to commercial buildings over 50,000 square feet and is structured around Energy Use Intensity targets, or an approved alternative investment criteria pathway, with deadlines phased by building size between 2026 and 2028.

Colorado, Building Performance Standards. Also organized around buildings over 50,000 square feet, requiring a 7% emissions reduction by 2026, rising to 20% by 2030.

Beyond these five, Denver, Chicago, Seattle, Philadelphia, St. Louis, Cambridge, Montgomery County, and a growing list of others each have their own version, with Maryland and additional states developing statewide programs behind them.

What the Standards Have in Common

Despite real differences in mechanics, per ton emissions caps in some cities, per square foot penalties in others, EUI targets elsewhere, most BPS programs share a few structural features. They apply above a specific size threshold, typically 25,000 to 50,000 square feet. They tighten in phases, with a first compliance period that's relatively achievable followed by sharply stricter limits a few years later. They generally allow multiple compliance pathways, direct emissions reduction, purchased renewable energy credits, or an approved alternative plan, rather than mandating one specific fix. And penalties are calibrated to make compliance the cheaper option, which is the entire point of the mechanism.

Why the Trend Line Only Points One Way

Where disclosure laws mostly plateaued once adopted, Building Performance Standards keep expanding, more cities each year, lower size thresholds over time, and tighter caps in every subsequent compliance cycle. Even buildings in a city without an active BPS today should treat that as a matter of when, not if, given how consistently jurisdictions have followed the same playbook once a neighboring city or state adopts one.

What This Means for a Building Owner

A BPS turns benchmarking, baselining, and audits from a best practice into a compliance requirement with a dollar figure attached. A building already tracking EUI, maintaining a real baseline, and acting on audit findings is, in effect, already most of the way toward BPS readiness. A building that isn't doing any of that has to build the entire measurement foundation and the retrofit plan under a deadline, which is a considerably more expensive way to arrive at the same place.
