The Commercial Building Energy Performance Map includes individual building energy performance data for commercial buildings 20,000 square feet and larger in an interactive map. There are various ways to interact with the map. You can zoom in and click on the color-coded dots to view more detailed information about the building.
Key Performance Metrics Defined
Site EUI is a building’s total annual energy use (generally, electricity plus natural gas) divided by its gross floor area. EUI indicates overall building energy performance and is measured in kBTU/sf (1,000 British thermal units per square foot). Higher EUIs show greater energy use, while lower EUIs indicate better performance. Weather-normalized site EUI also considers weather conditions within a particular year, allowing for comparison across multiple years.
ENERGY STAR score compares a building’s energy use to other buildings across the country on a scale of 1 (least efficient) to 100 (most efficient). A score of 50 represents the national median and buildings scoring 75 or higher may be eligible to earn ENERGY STAR certification. As of December 2023, over 200 commercial buildings in the Portland metro area have achieved ENERGY STAR certification at some point, distinguishing their exemplary energy efficiency.
