Reported emissions went from 341 tCO₂e to 272 tCO₂e over the same span (down 20%).

What does an ENERGY STAR score of 29 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 29 means the building performs better than about 29% of its national peers. BuildingCensus bands the score into report-card grades; 29 falls in band D — lowest band (1–54). It sits 46 points below 75, the threshold for ENERGY STAR certification. 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. 1820 Clydesdale Cooperative's 70.9 kBtu/ft² across 55,350 sq ft works out to about 3.9 billion Btu (1,150 MWh-equivalent) in 2017. Its source EUI of 116.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 322,566 kWh of electricity, 28,233 therms of natural gas and 1,657 thousand gallons of water for the year.

Which law requires 1820 Clydesdale Cooperative to report its energy use?

1820 Clydesdale Cooperative 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 2017 disclosure (source record dc:PM4000666:2017). 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.
