About Benchmarking and the Law

About Benchmarking

  • What is Energy Benchmarking?  Energy Benchmarking means tracking a building's annual energy use and using a standard metric to compare the building's performance against past performance and to its peers nationwide.  

  • What are the Benefits?  Benchmarking improves our understanding of energy consumption patterns; quantifies energy performance to compare against past performance and other similar buildings; helps identify energy saving opportunities within a portfolio of buildings; and manages business bottom line through consistent data collection and tracking.  Read more about the Benefits of Benchmarking.

Summary of the Benchmarking Law

In May 2014, the Montgomery County adopted Bill 2-14, Environmental Sustainability – Buildings – Benchmarking (PDF, 580 KB) and amended the original legislation by Bill 35-15 Environmental Sustainability – Benchmarking – Amendments in November 2015, which requires the County and building owners to:

  • Benchmark the energy use of their nonresidential buildings 50,000 square feet and greater in the county in ENERGY STAR Portfolio Manager,
  • Have those data verified by a Recognized Data Verifier the first year and every three years thereafter, and
  • Report data to the County annually for public disclosure.

The County has led by example by benchmarking its buildings first by June 2015. The first deadline for private buildings is June 2016. The Department of Environmental Protection (DEP) is responsible for the implementation of this law.

Official Guidance Document

All of the information on this website has been compiled into a downloadable document developed to guide you through the details of the benchmarking process. This guide provides background information and step-by-step instructions to help Montgomery County building owners comply with the Building Energy Benchmarking Law. Updates to this document will be communicated through the Montgomery County Benchmarking News and will be posted here.

Required Buildings and Deadlines

What is a Covered Building? A building covered under the Benchmarking Law is “any nonresidential building, or any group of buildings that have the same property identification number” that meet the square footage thresholds for the respective groups

Special Cases:

  • Multiple Buildings that Share a PIN/Tax ID: If you have a complex of buildings that share a property identification number (your Parcel ID or Tax ID), and their square footage adds up to the thresholds listed above, they are considered covered under this law (e.g., office campus with two buildings that are 30,000 square feet each and share a Tax ID).

  • A Building on Multiple Parcels: If you have a building that meets the thresholds, regardless of how many parcels or tax IDs or owners, the building is also considered covered under this law (e.g., shopping mall).

Building Groups and Deadlines: There are three groups required to benchmark annually under the Benchmarking Law in Montgomery County.  

Building Groups and Deadlines

*The Montgomery County law defines a covered building as a nonresidential building, or any group of nonresidential buildings that have the same property identification number, that meet the given thresholds and criteria. 


Covered Building List - Updated January 2016

DEP developed a preliminary Covered Buildings List to raise awareness about the Benchmarking Law. This list was created with current Maryland tax assessment records and the CoStar commercial building database.

Private Covered Buildings Inventory (provided by DEP) (MS Excel, 93 KB)

Important Information about the Covered Buildings Inventory (PDF, 354 KB)

Note: This inventory is an approximation, meant to raise awareness about the law and help identify the buildings covered by the law. Each building owner will need to confirm their own building square footage to determine coverage under the law.

Compliance is dependent upon the building owner’s record of their building square footage and the square footage on the parcel in total, regardless of the information on this inventory. This inventory will be used only as a tool by DEP, and should be considered the same by building owners and other stakeholders.

Montgomery County Building ID (MBID)

To be sure your building is counted as compliant by DEP, you will need to provide an additional ID number special to Montgomery County. Your building’s Montgomery County Building ID is your 8-digit Parcel Identification Number/Tax ID. The Parcel ID number is located in the upper right corner of your property tax bill. It would be the same as your account number. You can also locate this number online by visiting the Department of Finance’s Real Property Tax Account Information website.

Enter this MBID number in Portfolio Manager (Under the Details tab, select “Montgomery County (MD) Building ID” from the “Standard IDs” drop-down menu, and enter your MBID.

Special cases:

  • If you have multiple buildings on your parcel, you’ll create your MBID by using the 8-digit Parcel Identification Number/Tax ID number and adding an underscore and lower case letters beginning with “a”  (e.g., 01234567­_a, 01234567_b).
  • If you have a building on multiple parcels, you can list each 8-digit Parcel Identification Number/Tax ID number as your MBIDs, separating each with a comma.

Exemptions and Waivers

Downtown Silver Spring by Matthew Straubmuller via Flickr

Buildings exempt from the law include any County building, Group 1 covered building or Group 2 covered building with more than 10% of total gross square footage which is used for:

  • Public assembly in a building without walls,
  • Warehousing,
  • Self storage, or
  • A use classified as manufacturing and industrial or transportation communication, and utilities.

Waivers can be applied for in the cases where the building:

  • Is in financial distress, defined as the building is subject of a tax lien sale or public auction due to property tax arrearages; is controlled by a court appointed receiver; or was recently acquired by a deed in lieu of foreclosure;
  • Had average physical occupancy of less than 50% throughout the calendar year for which benchmarking is required; or
  • Is new construction and received its certificate of use and occupancy during the calendar year for which benchmarking is required.

If your commercial buildings would like to request an exemption or waiver, building owners must submit a Building Exemption/Waiver Application (PDF, 78 KB) to DEP no later than May 1 of each deadline year. For example, Group 1 buildings must apply for an exemption/waiver no later than May 1, 2016. 

Note: Use one form per building. Submit any relevant supporting documentation along with this application to justify the exemption/waiver. Exemptions and waivers must be reviewed and approved by DEP. 

What is Reported and Disclosed?

DEP will be requesting information to fulfill the Benchmarking Law’s reporting requirements and provide helpful information to guide benchmarking and energy efficiency program and policy planning. As such, DEP will be collecting a broader set of data than will eventually be disclosed. Except for metrics listed below under "What is disclosed?", DEP will not disclose the otherwise collected data. The collected data will be used to provide aggregate metrics and portfolio-wide benchmarks for reporting purposes.

The Benchmarking Law requires the County to make reported benchmarking information readily available to the public. The first year's data of each reporting group will not be disclosed. Disclosure will begin the 2nd year of each building group's reporting. Example: Disclosure will begin with data reported in 2017, the second year of reporting, for Group 1. Further details will be release closer to the first disclosure.

Read more about DEP Fact Sheet: Metrics Reported and Disclosed (PDF, 26 KB).


How to Comply with the Benchmarking Law

Collect Building and Energy Data

Gather your Building Information

What building information do you need to collect? Use the Montgomery County version of the Portfolio Manager Data Collection Worksheet to pre-assemble your information.


Have tenants? Building owners must request any space data needed in writing to the tenant no later than March 31 of each compliance year. Tenants must respond within 30 days of a request, per the Benchmarking Law.

  • Use the Montgomery County Tenant Information Request Letter Template (MS Word, 99 K) to explain your request, list information you’re seeking, and obtain tenant utility data using a data release form. Using this template is not required and is only meant as a guide.

Gather your Energy Data

You will need whole-building energy data for all your meters in order to benchmark properly in Portfolio Manager. There are two ways to obtain your energy data:

(1) Gather your utility bills

  • If you are the account holder of all your meters and all your energy data is available to you, we recommend collecting your bills for manual input.  (Portfolio Manager provides a bulk-upload option to easily upload multiple meters at the same time.)

  • If you have tenants, you can request that they share/send their energy data to you for the purposes of benchmarking. Or, read below for information on requesting data from your utility/utilities.

(2) Request data from your utility/utilities

If you have multiple meters in your building, it is possible to request whole-building/aggregate data from your utilities for benchmarking purposes. This service is most beneficial to building owners with several buildings and more than 5 meters in each building, particularly where tenants pay the utility bills.

  • If you have 5 or more meters, you can usually request whole-building/aggregate data without tenant authorization.

  • If you have 4 or fewer meters, you can request data from your utility but must obtain authorization from tenants to obtain their energy data. Building owners will need to receive authorization from each tenant, which are available on on your utility's energy benchmarking pages below:

Utility-Specific Information

  • Pepco customers can find information on getting their Pepco data at Pepco Energy Benchmarking
  • Washington Gas customers with 5 or more meters can find information on getting their gas bill data at Washington Gas Energy Benchmarking.
  • BG&E offers information on getting electronic BGE energy data at Automated Benchmarking.  
  • Potomac Edison – Account holders can either call customer service at 1-800-686-0011 to request and receive up to 2 years of historical monthly data via postal mail OR account holds can sign-up for or log-in to their account on the First Energy website and retrieve their data this way. Only account holders can request utility data. Note: If the account holder is a tenant, they will need to request their data and provide it to their building owner.  

When to Request Utility Data

Utilities will take up to 10 business days to provide your data; the wait can be longer as we approach compliance deadlines. Building owners are encouraged to request their data early.


Benchmark your Building in Portfolio Manager


About the Software: Portfolio Manager

In order to streamline the process of benchmarking, the benchmarking law has identified U.S. EPA’s free, industry-standard ENERGY STAR® Portfolio Manager Tool as the standard software for benchmarking and reporting. Read about it at

Method 1: Do-It-Yourself Benchmarking

Portfolio Manager is built to be user-friendly and accessible for in-house staff to benchmark their buildings. In many cases, ENERGY STAR has found accounting, operations, and building management staff are entering data into Portfolio Manager. If you choose to Do-It-Yourself, below are some helpful tools to guide you.

Portfolio Manager Resources

  • Portfolio Manager Quick Start Guide (PDF, 508KB) offers the basics to setting up your Portfolio Manager account, including adding your property, entering your energy data, and seeing your results.
  • Details on Entering Your Utility Bill Data (PDF, 567KB) walks you through the steps to set up a meter and correctly enter data, add data to an existing meter, complete spreadsheet uploads, and information on Web Services (automated benchmarking).
  • Portfolio Manager Trainings offers both live and recorded webinars, written and video tutorials, and how-to’s for specific functions of the software.
  • Portfolio Manager Technical Support offers expert advice and guidance on how to benchmark your building(s) in Portfolio Manager.

Montgomery County DEP is working very closely with ENERGY STAR and defers to their technical support for guidance in benchmarking in the software.  Benchmarking per the ENERGY STAR Portfolio Manager guidelines are a best practice for compliance with the Benchmarking Law.


Method 2: Hire an Energy Service Company to Benchmark

Benchmarking is a common and regular practice for any energy efficiency or conservation project. Montgomery County and the region are home to many energy service companies that offer an array of services to help you manage your energy use. Many of these same companies are experienced in benchmarking and can help you benchmark your building.

What to Look For in an Energy Service CompanyDEP cannot endorse a particular company or business, but we recommend asking a few companies about their experience for benchmarking, their ability to help deliver energy savings, and other services they offer. You can ask for quotes from multiple companies, and they may be able to help you benchmark, and access to improve your building's energy performance. 

Where to Look for an Energy Service Company: DEP does not endorse a particular company or business, but we can direct you to existing lists of energy service companies that do similar work.

  • Trade Ally Programs offer a list of companies that assist utilities with energy efficiency improvements, many of which can offer benchmarking services:
  • ENERGY STAR Partners have a made a commitment with ENERGY STAR to support benchmarking and improving energy performance
  • Montgomery County Benchmarking Ambassadors (PDF, 311 KB) attended a special 3-hour "train-the-trainer" taught by EPA ENERGY STAR Portfolio Manager Staff, got the details about complying with Montgomery County's law, and learned how to access data from utilities.

Data Verification Requirement

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.


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, the building owner must enter the following details about the Recognized Data Verifier in the Property Notes field on the Details tab for each Covered building in Portfolio Manager:

  • Full Name
  • Credential (name/acronym)
  • Credential identifer (ID number)
  • Contact information (verifier's email address and phone number)


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:

Acceptable Verification Credentials
Verification Credential Institution / Association
Professional Engineer (PE) National Society of Professional Engineers
Licensed Architect National Council of Architectural Registration Board
Registered Architect (RA) American Institute of Architects
Certified Energy Manager (CEM) Association of Energy Engineers (AEE)
Building Energy Assessment Professional (BEAP) ASHRAE

2CPM must have been achieved with the following three functions selected and illustrated in the Experience Form: #3, #30, and #33.


Alternative Verification 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.

Before Reporting

Prior to using this reporting link to report to DEP, be sure you have fulfilled the following requirements:

  • Enter all energy, water, and space use information in Portfolio Manager. Enter all data from January 1 – December 31 for the calendar year being reported for each property.
  • It is helpful to run Portfolio Manager’s tool to check for possible data errors prior to using this template to ensure that you have no fatal errors in your data submission. The Data Quality Checker timeframe should align with the calendar year being reported.
  • Identify your properties with your Montgomery County Building ID (MBID) in Portfolio Manager. 

Use our handy Energy Benchmarking and Reporting Checklist (PDF, 523 KB). This step-by-step checklist will ensure that you've followed all the right steps before reporting data to DEP. 

How to Report

Reporting to the County is easy once you’ve completed your benchmarking in Portfolio Manager. DEP will provide a reporting link closer to the first compliance deadline that will facilitate electronic reporting to the County through Portfolio Manager. There will be a new reporting link for each compliance year. Check the DEP Benchmarking website or sign up for the Benchmarking News in the months preceding deadlines for the reporting link. After clicking the link, log-in to your Portfolio Manager account and follow the step-by-step instructions on the screen.

If you are an energy service company submitting benchmarking data on behalf of a Montgomery-County-based client, you must report that you are submitting data on behalf of someone else.

**Calendar Year 2015 Reporting Link for Group 1 Buildings and County Facilities**

This link will take you to the ENERGY STAR Portfolio Manager account log-in screen—after logging in, you’ll see step-by-step instructions on the Data Request page. Data must be submitted to DEP no later than 5 pm Eastern on Wednesday, June 1, 2016. 

After sending your data to DEP, retain the auto-generated confirmation email you’ll receive from Portfolio Manager, as well as the signed Data Verification Checklist from your recognized data verifier and other records related to the energy reporting process. DEP will review the data you reported to us and follow-up with any questions or recommendations.

After Reporting

If you need to make a change after you reported data, but before the deadline, go ahead and make your change and re-report your data to DEP. As long as it’s the same building in Portfolio Manager, the updated information will automatically replace what is reported to us. If it is after the deadline, contact DEP at so we can be sure to capture your most accurate data.


The Benchmarking Law is enforceable under Method 2 regulations (including fines for noncompliance), and any violation of the law is a Class A violation. DEP will send out Notice of Violation to any building owner of a Covered building who does not comply with the Law. Note that DEP is available to assist any building owner to help them comply with the law.


Beyond Benchmarking: Saving Energy & Recognition

Improve Your Building Energy Performance

Once your building has been benchmarked, you may find that there is room to improve energy efficiency (and maybe raise your score!). Simple adjustments to equipment start time, operations parameters, occupant behavior, and controls can reap significant energy and cost savings.

Utility Incentives

Commit to making energy improvements, and use your benchmarking data to discuss with your utility what incentives are available for saving energy. Learn more at:
