What does an ENERGY STAR score of 76 mean?

ENERGY STAR scores run from 1 to 100 and are computed by the EPA's Portfolio Manager as a percentile against similar buildings nationwide, adjusted for climate, size and use: a score of 76 means the building performs better than about 76% of its national peers. BuildingCensus bands the score into report-card grades; 76 falls in band B — above median (70–84). Scores of 75 or higher meet the threshold for ENERGY STAR certification; certification itself is a separate, verified application that the disclosure does not record. In Washington, DC, 47% of scored buildings are at 75 or above.

Site energy-use intensity (EUI) is the energy a building uses on site in a year divided by its floor area, in thousand Btu per square foot — lower is more efficient. Chesterfield Cooperative, Inc.'s 65.2 kBtu/ft² across 81,996 sq ft works out to about 5.3 billion Btu (1,567 MWh-equivalent) in 2018. Its source EUI of 102.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 471,427 kWh of electricity, 37,409 therms of natural gas and 2,798 thousand gallons of water for the year.

Which law requires Chesterfield Cooperative, Inc. to report its energy use?

Chesterfield Cooperative, Inc. reports under the Clean and Affordable Energy Act / BEPS, the legal basis of Washington, DC's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2018 disclosure (source record dc:PM4019576:2018). DC's Building Energy Performance Standards (BEPS) require buildings below the performance standard to improve over compliance cycles (the first ends December 31, 2026; later cycles run five years), with penalties for buildings that fail to meet their pathway.
