City of Portland Energy Benchmarking

Welcome to NW Natural's Energy Benchmarking page for commercial building owners and managers. Here you will find instructions on how to request your natural gas usage. Any questions regarding EPA's Energy Performance Tool should be directed to the Bureau of Planning and Sustainability.

City of Portland Energy Performance Reporting Background

To reduce energy costs and carbon emissions, the City of Portland requires commercial buildings over 20,000 square feet to track their energy performance with ENERGY STAR Portfolio Manager and report it to the city on an annual basis.

Requesting natural gas usage data

Prepare to complete the Natural Gas Usage Request Form
You will have to input the meter number for each natural gas meter servicing your property. In most cases, this information can be found on your monthly bill, or on the meter itself. Click here for images of meters (4 images). If tenants within your property are billed separately for natural gas service, meter numbers will have to be supplied for those meters, as well.
Property owners with 1-4 tenants must submit a signed Tenant Data Release Form from each tenant in order for NW Natural to release their natural gas usage information.
If five or more tenants occupy the property, or if the property is owner-operated, release forms are not necessary but all the tenants meter numbers are still required.
Within the Natural Gas Usage Request Form, you will be asked to review and agree to the Terms and Conditions.
