Chicago Energy Benchmarking Ordinance

Who's covered

Chicago's Building Energy Use Benchmarking Ordinance covers buildings of 50,000 square feet and above in gross floor area -- "and above" is inclusive, so a building at exactly 50,000 sq ft is covered, unlike some other cities' exclusive thresholds. Covered buildings span a wide range of residential and commercial structures, not just office towers.

A specific, named list of building types is exempt even above 50,000 sq ft:

• Buildings used as outdoor stadiums, factories, hazardous material facilities, or storage facilities
• Buildings used for accessory outdoor uses (barns, fieldhouses, and similar structures)
• Buildings undergoing financial distress
• Buildings with an average physical occupancy of less than 50% throughout the calendar year
• Buildings constructed during the current calendar year
• Buildings that had a change of ownership during the calendar year

If your building is unusual -- a factory, a mostly-vacant property, or one that just changed hands or was just built -- check the exemption list against the city's Covered Buildings List before assuming standard reporting applies; several of these exemptions are calendar-year-specific and don't carry forward automatically once the qualifying circumstance ends.

Every covered building's data has to be verified by a licensed architect or professional engineer once every three years, in the first year of each building's own three-year cycle -- the specific year is published in the "Verification Year" column of the city's Covered Buildings List spreadsheet, so it isn't the same calendar year for every building. Self-verification by the owner does not satisfy this requirement.

Key dates

June 1, every year, for the prior calendar year's data, submitted through an ENERGY STAR Portfolio Manager (ESPM) data request from the City. This is the same calendar deadline used by a large cluster of other major benchmarking programs nationally (LA EBEWE, California AB 802, Seattle, Denver, and others all also land on June 1), so if you own buildings in multiple of these jurisdictions, June 1 is the single busiest day on your compliance calendar, not just Chicago's.

Chicago's benchmarking program went through a significant operational relaunch: in December 2025, the Department of Environment (which now administers the program, following a reorganization announced March 5, 2026) relaunched it with a new support platform built by ClearlyEnergy, branded BEAM (accessible at chicago.beam-portal.org). Worth flagging explicitly if you also own property in New York: NYC's Local Law 97 uses its own, completely separate system also branded "BEAM." The two are unconnected -- Chicago's BEAM is a support/helpdesk and data-insights layer sitting on top of the same ESPM data-request submission mechanism (it is not a separate filing portal the way NYC's BEAM is), while NYC's BEAM is itself the filing portal for an entirely different law.

As of this writing, Chicago's Department of Environment has a draft rules update open for public comment through July 10, 2026 -- worth monitoring if you're planning compliance workflows more than a year out, since rule changes could affect verification timing or exemption detail.

Penalties

The real penalty is not "$100/day," despite that figure circulating among some compliance vendors. Chicago's Municipal Code (§ 18-14-101.5(b)) sets a $100 fine for the first violation, plus an additional fine of up to $25 per day for each day the violation continues. That's a materially different, and initially smaller, number than a flat "$100/day" misreading would suggest: a violation left open for 30 days works out to roughly $100 + (30 x $25) = $850, not $3,000. The gap between the two framings gets larger the longer a violation drags on, so getting this number right matters for anyone budgeting compliance risk.

Beyond the dollar fine, late or non-filers are assigned a zero-star Chicago Energy Rating. Chicago translates benchmarking results into a public-facing rating placard system for the building, separate from (though informed by) the ENERGY STAR score ESPM itself generates -- a building that hasn't reported shows up with the lowest possible public rating, a reputational consequence independent of the dollar fine.

There is no registration or filing fee to report under Chicago's ordinance -- a point of contrast with programs like NYC's LL97 (which charges filing fees under 1 RCNY § 101-03) or LA's EBEWE (a $61/year local registration fee). The entire cost of Chicago compliance, outside of the occasional 3-year licensed-verification engagement, is the labor of gathering and entering the data.

Step-by-step: how to comply

1. Confirm your building is 50,000 sq ft or larger and doesn't fall into one of the named exemption categories (factories, storage facilities, low-occupancy buildings, newly constructed buildings, buildings that changed ownership this year, and similar). We check your building against the city's published Covered Buildings List and flag anything that looks exemption-eligible -- but if your building's situation is genuinely borderline (a partially vacant building approaching the 50% occupancy line, for instance), that's worth confirming directly with the city.
2. Set up (or claim) your property in ENERGY STAR Portfolio Manager with a "Chicago" Standard ID. We handle this setup once you've authorized access.
3. Enter 12 months of whole-building energy data for the prior calendar year and respond to the City's ESPM data request before June 1. This is the part we fully automate once your utility feed is live.
4. Check your building's Verification Year in the Covered Buildings List. If this is your building's verification year, arrange for a licensed architect or professional engineer to verify the submitted data. We track your building's 3-year verification cycle and remind you well ahead of your verification year -- but the licensed professional's sign-off itself has to come from a real, license-verified person, the same way LA's A/RCx audits do.
5. If something's stuck, use the BEAM helpdesk (chicago.beam-portal.org/helpdesk) or the free Building Energy Hub resource rather than an unsolicited third-party vendor -- the city explicitly warns that official communications are always marked "CITY OF CHICAGO OFFICIAL NOTIFICATION," precisely because unauthorized third parties have sent confusing or inaccurate benchmarking outreach in the past.

What we handle

Chicago benchmarking is a clean, fee-free, ESPM-only filing for most owners -- the complexity is concentrated almost entirely in the exemption list and the once-every-three-years licensed verification requirement, not in the annual filing itself. Run the compliance checker below to confirm your building's covered status and verification-year timing, then join the waitlist. What stays yours: arranging the licensed architect or PE for your verification year, and confirming any exemption claim (financial distress, low occupancy, and similar categories aren't always self-evident from the outside).

Frequently asked questions

Does Chicago publish an ENERGY STAR score, or something else?

Chicago translates ESPM benchmarking results into its own public-facing Chicago Energy Rating placard system, distinct from (though informed by) the ENERGY STAR score ESPM itself calculates. Buildings that fail to timely report are assigned the lowest possible rating -- zero stars.

Who is allowed to perform the required 3-year data verification?

Only a licensed architect or professional engineer. Self-verification by the building owner does not satisfy the requirement, and the specific year your building owes a verification (not necessarily this year) is published in the Covered Buildings List's "Verification Year" column.

Is the penalty really "$100 per day"?

No -- that's a common but inaccurate simplification. The actual structure under Municipal Code § 18-14-101.5(b) is a $100 fine for the first violation, plus up to $25 per day for each day the violation continues after that. The two framings diverge more the longer a violation remains open, so treat any "$100/day" figure you see elsewhere with caution.

What happens if I never file at all?

Beyond the escalating $100-plus-$25/day fine, a building that doesn't report is publicly assigned a zero-star Chicago Energy Rating -- a visible, ongoing reputational consequence layered on top of the dollar penalty, not a one-time paperwork issue.

Is Chicago's "BEAM" platform the same system as NYC's Local Law 97 BEAM portal?

No, despite the identical branding. Chicago's BEAM (run by ClearlyEnergy, launched with the program's December 2025 relaunch) is a support and data-insights layer sitting on top of the same ESPM data-request submission Chicago has always used. NYC's BEAM (nyc.beam-portal.org) is itself the actual filing portal for an entirely different law, Local Law 97's emissions reporting. If you own buildings in both cities, don't assume familiarity with one "BEAM" tells you how the other works.

Is there a registration fee, like some other cities charge?

No. Chicago's program doesn't charge a filing or registration fee -- a contrast with, for example, LA's EBEWE ($61/year local registration fee) or NYC LL97 (which has DOB-published filing fees). The cost of Chicago compliance is the labor of data entry and, once every three years, arranging a licensed professional's verification.

My building is a warehouse -- does the factory/storage exemption cover me?

Not necessarily -- the city's exemption list names "storage facilities" and "factories," but doesn't spell out exactly where a generic warehouse or distribution center falls on that line (other jurisdictions, like California's AB 802, explicitly exclude warehouses from a similarly worded industrial exemption, so don't assume the categories translate). If your building's use is genuinely closer to distribution or logistics than manufacturing or bulk storage, confirm against the Covered Buildings List or with the Department of Environment directly rather than assuming the exemption applies.
