What does an ENERGY STAR score of 46 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 46 means the building performs better than about 46% of its national peers. BuildingCensus bands the score into report-card grades; 46 falls in band D — lowest band (1–54). It sits 29 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. Bader Condominium's 92.9 kBtu/ft² across 68,360 sq ft works out to about 6.4 billion Btu (1,861 MWh-equivalent) in 2018. Its source EUI of 175.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 889,520 kWh of electricity, 33,157 therms of natural gas and 2,376 thousand gallons of water for the year.

Which law requires Bader Condominium to report its energy use?

Bader Condominium 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:PM4376327:2018). 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.
