Benchmarking refers to the process of reporting energy consumption to the local municipality through the USEPA Portfolio Manager website. You receive a benchmark score of your buildings energy efficiency compared to similar buildings. The system ranks energy performance on a scale of 1-100, with a higher score indicating a more efficient building. A score of 75 or more qualifies the building for the EPA energy star designation. Benchmarking helps owners assess energy use and gauge performance relative to other buildings in the marketplace.
