The public can view and compare energy efficiency information for more than 800 commercial buildings within the city of Portland. Similar to labels on consumer products, such as cars and appliances, building energy ratings help tenants and prospective purchasers understand how much energy a building uses and how that might affect operating costs.
In 2015, the City of Portland passed an ordinance requiring buildings that are 20,000 square feet and larger to track and report energy performance. Buildings are the single largest contributor to carbon emissions in Multnomah County, making them a critical area of focus in the City's efforts to combat climate change. Existing commercial buildings have shown little improvement in energy efficiency over the past three decades.
Across the nation, cities are addressing this problem through mandatory energy reporting and disclosure requirements. Building managers enter energy usage information and building details into ENERGY STAR® Portfolio Manager®, a free online tool that calculates metrics describing how the building performs. Tracking this information is the most common first step for a building owner in considering whether to make operational adjustments or building upgrades that could ultimately result in cost savings and carbon emissions reductions.
Building managers report their energy performance metrics to the City annually and that information is then made publicly available. The data reported in 2017 has been published and can be explored in an easy-to-use, interactive online map. Users can view and compare buildings according to their size, use type, energy performance, compliance status and whether the building’s score has been verified by professional. The same information can also be viewed in a sortable spreadsheet.
In addition, each year the City analyzes the data and publishes an annual report summarizing broader trends in energy performance. The analysis examines how buildings of different uses and ages perform compared to their peers and how energy performance has changed over time.
