# Chicago Energy Benchmarking Guide: June 1 Filings, 3-Yr Verification & 0–4 Star Placards

> Jurisdiction: Chicago, IL | Status: Live (June 1 Benchmarking · 3-Yr Licensed Verification · 0–4 Star Placard Posting) | Reviewed: 2026-11-14

**Short answer:** Under [Municipal Code of Chicago Chapter 18-14](https://www.chicago.gov/content/dam/city/progs/env/EnergyRating/2020_Chicago_Energy_Rating_System_FAQs.pdf), Loop skyscrapers, industrial-converted lofts, and residential towers **>=50,000 sq ft** comply with a three-layer transparency regime: annual **June 1** ENERGY STAR Portfolio Manager submissions, **triennial third-party professional data verification**, and mandatory physical posting — plus sale and lease transaction disclosure — of Chicago's **0–4 Star Energy Rating placard**.

Because Illinois maintains no statewide building benchmarking law (proposed [Illinois HB 3673](https://bcesg.org/illinois-climate-corporate-accountability-act-hb-3673-watch/) targets corporate Scope 1/2/3 disclosures only), real estate obligations cluster locally in Chicago (>=50k sf) and neighboring Cook County suburbs covered in our [Evanston HBO & Oak Park Benchmarking Guide](https://bcesg.org/evanston-healthy-buildings-oak-park-benchmarking-illinois-guide/).

### Statutory Status at a Glance
- **Covered Scope (>=50,000 sq ft):** All commercial, institutional, and multifamily residential buildings >=50k sq ft inside Chicago.
- **Triennial Licensed Verification:** Every three years (and first reporting year), an Illinois-licensed architect, professional engineer (PE), Certified Energy Manager (CEM), BOC, or ASHRAE BEAP must sign the Portfolio Manager Data Verification Checklist.
- **0–4 Star Rating System:** Based on ENERGY STAR 1–100 score (or two-year improvement points), scored out of 4 stars and printed as a municipal placard required in visible entrance lobbies and real-estate sale/lease listings.
- **ComEd & Peoples Gas Sync:** Automated whole-building aggregated utility reporting streamlines multi-tenant residential condominium and commercial office uploads ahead of June 1.

## Handling Triennial Data Verification & 0–4 Star Placard Sales Disclosures

Commercial buyers and leasing counsel routinely catch sellers forgetting Chicago's two secondary duties under Ch. 18-14: properties must display their current-year 0–4 Star placard at the main public entrance AND include the rating inside sale contracts and tenant lease materials. Even a timely June 1 upload draws administrative notices if the building skipped its required 3-year credentialed verifier stamp.

Confirm your Chicago Energy Benchmarking ID year-in/year-out whether this calendar year sits on a verification cycle (years divisible by three from initial cohort compliance) and ensure Condo Association (HOA) boards retain copies in annual ownership packs.

- **Score Optimization Ahead of June 1:** Audit operating hours, server-room square footage, and vacant spaces inside Portfolio Manager — correcting under-counted occupancy boosts ENERGY STAR star tiers legitimately.
- **Sale/Lease Contract Clause:** Attach the PDF Star Rating certificate in every Loop commercial lease rider and condo disclosure package.

## Frequently Asked Questions

### Do Chicago buildings need third-party verification every year under Ch. 18-14?

No. Annual June 1 Portfolio Manager reporting is required every year, while third-party verification by a qualified licensed professional (PE, AIA, CEM, BOC, etc.) is required in year one and every three years thereafter.

### Where must Chicago's 0–4 Star Energy Rating placard be posted?

Covered buildings >=50,000 sq ft must display the municipal 0–4 Star placard in a prominent location at the building's public entrance and disclose the rating upon sale or commercial/residential lease.
