How to navigate BERDO and BEUDO reporting like a pro

Data reporting doesn’t have to be a headache. Based on our experience as third-party verifiers, we’ve identified the most common traps people fall into as they navigate BERDO and BEUDO, and how to avoid them.

With spring just around the corner, building owners in Boston and Cambridge are gearing up to navigate BERDO and BEUDO in the 2026 reporting season. BERDO (May 15) and BEUDO (May 1) deadlines are fast approaching, and for many, this year marks the start of emissions requirements and potential compliance payments or fines. We’ve compiled a list of common pitfalls we see in data reporting and third-party verification to help you report easily and efficiently.

1. Start early with your utility provider

Your utility provider holds the keys to your report, but they aren’t always the fastest communicators.

Check with your utility provider to ensure that all meters are included in the data request. It can be handy to have your bills or meter numbers in front of you when making the request.
Data processing can take 1–2 weeks. As deadlines approach, wait times grow. Request your data early to avoid a last-minute scramble.
Ensure your data covers the full calendar year (January 1, 2025 through December 31, 2025).
Don’t forget to include on-site solar generation if required by your municipality.

2. Dodge data entry errors in Portfolio Manager

When entering data into EnergyStar Portfolio Manager (or a different reporting tool), triple check that your units of measure match what is listed on your utility bills. Unit errors can cause huge discrepancies in your reporting.
Portfolio Manager does not automatically save data when it’s entered, so save your changes early and often.
Compare this year’s data to previous years for a gut check. Does it follow the same trend? Are there any massive spikes or dips? If your data looks different, investigate the reason. Have you updated your equipment? Did occupancy change? Be ready to submit this information to your verifier.

3. Represent building information correctly

Reporting the wrong square footage or usage type can unfairly impact your emissions score or cause your submission to be flagged by the municipality.

Have your building identification numbers, tax parcel numbers, and other identifiers on hand when reporting
Reporting guidelines are very specific about what square footage is eligible (and what isn’t). Don’t guess the square footage, check architectural drawings if necessary to ensure precise numbers.
If your building has multiple uses (e.g., retail on the ground floor, residential on other floors), list them accordingly. Categorizing your building accurately can benefit you when it comes time to comply with emissions standards.

4. Don’t wait to lock in a third-party verifier

Verifiers can get busy as May approaches. Reach out to them early to secure your spot.
Ensure you have shared your properties on Portfolio Manager with your verifier and the reporting entity. If you self-report your data, be ready to also share details about your building and the collected utility bills with your verifier.
If you know you’re going to miss a deadline, reach out to the city and request an extension as early as possible.
