Benchmarking Law Compliance

Compliance with the County's Benchmarking Law is a multi-step process that must be completed annually. By following the steps below, you’ll be able to benchmark your building, have the data verified, and report data to DEP quickly and easily.


Step 3: Data Verification

Verification is considered an industry best practice, and ensures that building and energy data entered into Portfolio Manager are accurate. The purpose of verification is to enhance the quality of data being reported collectively through the Benchmarking Law. Verification requires a second pair of eyes from someone with knowledge about Portfolio Manager and building energy performance.

The Benchmarking Law requires that building owners complete a verification process the first year of compliance and every 3 years after.

Buildings in Group 2 (50k sq. ft. up to 250k sq. ft.) that were first covered in CY 2016 and submitted by the 6/1/2017 deadline are now required to complete and report updated data verification information for CY 2019 data by 6/1/2020. Visit the data verification section of our site for more information. 


How to Complete Verification

The Recognized Data Verifier should review the Data Verification Checklist provided by Portfolio Manager (under the Reports Tab and in the top right box) and confirm the building profile information and meter data. The required verification does not include looking at water metrics or indoor air quality, nor does it require a site visit.

This Data Verification Checklist must be printed and signed and given to the building owner. This signed Verification Checklist does not need to be submitted to DEP, unless it is requested by DEP (DEP is authorized to request documentation). Therefore, building owners must retain the most recent signed Data Verification Checklist for at least three years.

Once verification is completed, please visit your property in Portfolio Manager and enter verifier information into the fields provided on the Details tab in Portfolio Manager. Instructions and screenshots for doing so are here.

For more information on how to complete verification, please review DEP’s How-to Guide for Data Verification (PDF, 160KB).


Acceptable Recognized Data Verifier Credentials

Building owners must demonstrate that reported benchmarking information is verified by a "Recognized Data Verifier." The following is a list of credentials that DEP has identified as acceptable to be a Recognized Data Verifier:

1 RPA must have been achieved with the elective course, Asset Management OR achieved with completion of at least 3 of the 5 Sustainability/High Performance Experience Criteria
2CPM must have been achieved with the following three functions selected and illustrated in the Experience Form: #3, #30, and #33.


Finding a Recognized Data Verifier

Building owners can use any in-house or third-party professional who holds an active credential listed on the Acceptable Verification Credentials list above. While DEP cannot recommend or refer you to a Recognized Data Verifier directly, we do have a list of Benchmarking Ambassadors – these volunteers have received training on the Benchmarking Law and Portfolio Manager, and some of the Ambassadors hold an acceptable Recognized Data Verifier credential.


Alternative Compliance Path

Alternatively, Covered buildings can meet the verification requirement if the owner can demonstrate that the building has achieved the ENERGY STAR building certification for at least 6 months of the calendar year being benchmarked.

If a building owner is using this verification path for a Covered building, please indicate this in the Property Notes field by stating “ENERGY STAR Certification used for verification” and the month and year certification was achieved.
