Benchmarking Instructions

Multifamily and non-residential buildings greater than 20,000 sf (excluding parking) must be accurately benchmarked in the free, online ENERGY STAR® Portfolio Manager® tool and shared with the City of Seattle to successfully report data annually (for the prior year's energy use).

Benchmarking and reporting is a multi-step process. This page presents detailed instructions on how to comply with the benchmarking ordinance. Whether it's your first time benchmarking, you are conducting data verification, or you're looking to update your existing profile for annual reporting, review the resources below for instructions. 

***Impact to Puget Sound Energy Customers***

Puget Sound Energy’s (PSE) new EnergyCAP® tool has replaced the MyData reporting platform.

  • If you were previously a MyData user and your account did not successfully migrate you must create an EnergyCAP® account and re-enroll in the automated data exchange process as a new user. Please consult the instructions in the Puget Sound Energy Data Exchange section of our Benchmarking How To Guide
  • If you are working with a newly constructed building that is setting up reporting for the first time, or have acquired a building through change of ownership or management and need to re-start the benchmarking process from the beginning—you will also need to create a new EnergyCAP® account and complete the steps to enroll in automated data uploads to ENERGY STAR® Portfolio Manager. 

Please note, if you have an existing EnergyCAP® account with buildings enrolled in automated data uploads, you must add the new building to your existing account. Contact the benchmarking team at or schedule a 1:1 session to access free technical support for your EnergyCAP account.

Submitting Your First Benchmark Report

If benchmarking and reporting for the first time, you must complete all the following steps to comply with Seattle's benchmarking requirements.

1 - Collect Data
Gather information about the building's use(s) and the energy utilities that serve both common area and tenant spaces.

2 - Set Up Property
Create an EPA Portfolio Manager account and add property.

3 - Obtain Energy Meter Usage Data
Buildings are required to report 12 months of data annually for all fuel sources serving the building. Utilities offer data upload services to help you report tenant energy use to your Portfolio Manager account. 

4 - Confirm Energy Use
Verify all your data has been entered and you can get an energy score.

5 - Add Contacts
Add the City of Seattle Annual Reporting as a contact in Portfolio Manager to submit your report.

6 - Share Building
Share the building in Portfolio Manager with City of Seattle using your Seattle OSE Building ID.

Portfolio Manager Annual Updates

Seattle's Energy Benchmarking law requires owners to annually confirm that Portfolio Manager accounts are updated and correctly reporting performance to the City. If you reported to the City of Seattle last year, or took over an account that reported last year, use the Annual Update Checklist to confirm property details data and energy consumption data is complete and accurate for the reporting year.

If you have taken over management or ownership of a building you might be able to have the previous account transferred to you. See this FAQ for more. If you can't get access to the previous account you will need to start from the beginning and submit a new report. See "First Time Benchmarking and Reporting" for instructions. 

Tips for Annual Updates 

  1. Check for missing data - all active meters in Portfolio Manager must have 12 moths of data for the required reporting year. 
  2. Check for data anomalies - does your EUI seem significantly higher or lower than the previous year? Check the monthly consumption entries for 0's or other errors 
  3. Update space uses - Did your building have any vacancy or change of tenants? Make sure the spaces in Portfolio Manager are updated to reflect actual property uses and use details for the required reporting year.  The City of Seattle requires data center, laboratory, and restaurant property uses to be included regardless of space use size. For help on how to account for vacancy or update property types and property use details click on the "Portfolio Manager Resources" at the bottom of this instructions page.

Data Verification

The City of Seattle flags annual benchmarking reports with possible errors and requires owners to complete a data verification process. Possible errors are identified based on a few factors, such as extremely high or low energy metrics, a possible missing fuel compared with previous years, or drastic increases or decreases in energy data. As benchmarking is a best practice for energy management, tracking trends over time, and comparing building performance, the benefits of benchmarking cannot be realized without accurate data.

Reports with possible errors require additional verification, and corrections where required, to be considered compliant. If your report is flagged for verification, you must complete all data verification requirements (see worksheet below) and submit the online verification form.

The most common types of errors found and corrected in Portfolio Manager are incorrect building square footage, incorrect benchmarking of parking square footage, incorrect property types, incorrect or missing secondary space types, missing fuel sources, missing tenant meters or automated data exchange error(s) in monthly consumption.

The resources below will help you complete the verification process. 

Data Verification Requirements Worksheet (pdf) outlines the steps required to verify Portfolio Manager accounts for data accuracy. Use the worksheet to complete the data verification process and make corrections as needed in Portfolio Manager. 

Verifying Benchmarking Accuracy (video) this training video compliments the worksheet and outlines the steps required to verify Portfolio Manager accounts for data accuracy. Watch for more in-depth tutorials and guidance on how to complete the data verification process and make corrections as needed in Portfolio Manager. 

Default Data

Reports with "default values" for the ENERGY STAR score are required to make corrections. Default values are provided within Portfolio Manager to help owners get a quick ENERGY STAR score, when the exact values for the property use details are not yet known. Actual values must be used in EPA Portfolio Manager to obtain an accurate ENERGY STAR score for your property. 

Learn how to fix default data using these guides:

Correcting Default Values (pdf) outlines the steps required to correct default values in Portfolio Manager for all space uses. 

Accurate annual reporting is a requirement per Seattle Municipal Code (22.920.120). 

After you have finished submitting your benchmarking report or made annual updates, you can check your building's compliance status for the current reporting year with the online compliance tool.

The EPA provides additional guidance  for specific benchmarking scenarios. The following resources outline how to correctly benchmark certain building types or space uses in Portfolio Manager.

How to Benchmark a Campus

Use the EPA's guidance with the Seattle Benchmarking How to Guide if you have a "campus" style property.  

Data Center Benchmarking FAQs

The Data Center Property Use Type is for sophisticated computing and server functions, and not server closets or similar spaces. Data centers typically include raised floors, uninterruptible power supplies, and dedicated power and cooling systems. See What is the definition of Data Center? to determine if you should create a separate data center space use in your building's Portfolio Manager account. 

How to Account for Vacant Space

Please review EPA guidance on how and when to account for vacant space in Portfolio Manager for your building. Vacant space is only required as a space use entry for certain building types.

Number of Workers on Main Shift

You must update the building's number of workers to reflect any changes to the number of employees physically present in the building in 2020, 2021 and 2022. This use detail is where employees switching to remote work will show up. Do not update the number of computers, when accounting for remote workers. The EPA recommends several approaches to accounting for vacant space in buildings.

How to Enter Parking

Use this guidance to determine how and when to include parking in Portfolio Manager. 

How to Account for Solar

Follow EPA guidance on how to account for a building's solar energy production in Portfolio Manager. 

Can't find what you're looking for? The EPA has a searchable online question and answer bank that clarifies many commonly asked Portfolio Manager scenarios. The EPA also sponsors a help desk support center where you can submit your specific benchmarking question or request for interpretation.
