Energy Performance Score System Standards for Commercial Buildings


Persons producing energy performance scores must have completed training in the building energy assessment software and energy performance score system used to produce the score.


Building energy assessment software used to produce the score must be approved the U.S. Department of Energy.


An energy performance score for an existing commercial building must be an operational rating based upon the actual energy usage of the building and shall utilize utility data.


An energy performance score for a new commercial building must be an asset rating based on the projected energy consumption of the building and may include a physical inspection of the building.


An energy performance score must include an explanation of the score and the assumptions used to derive the score, the date of the score, and the name of the person that produced the score.


Commercial energy use must be displayed in annual Kbtu per square foot as determined by approved energy modeling methods, using standard occupancy profiles for the building type. The annual energy consumption of each fuel (electricity, natural gas, oil, propane, etc) must be displayed in retail units.


Energy performance score reports may include:


A benchmark score based on a similar building built to state building code standards, a similar building that represents Oregon or national average energy consumption, or any other comparable building; and


The estimated amount of carbon dioxide equivalent (CO2e) emissions, in metric tons, associated with the building’s energy consumption based on the carbon intensity, as reported on the department’s website, of the electricity provided by the electric utility that serves the building, natural gas and other fuel types used in the building.
