How has 2100 MLK's energy performance changed over time?
BuildingCensus holds 11 Washington, DC disclosures for 2100 MLK, covering report years 2014–2024. Its ENERGY STAR score went from 24 in 2018 to 53 in 2024 (+29 points); its best year on file was 2023, at 58. Site EUI moved from 94.5 kBtu/ft² (2014) to 76.7 kBtu/ft² (2024), a 19% decrease. Reported emissions went from 903 tCO₂e to 517 tCO₂e over the same span (down 43%).
What does an ENERGY STAR score of 53 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 53 means the building performs better than about 53% of its national peers. BuildingCensus bands the score into report-card grades; 53 falls in band D — lowest band (1–54). It sits 22 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. 2100 MLK's 76.7 kBtu/ft² across 76,857 sq ft works out to about 5.9 billion Btu (1,728 MWh-equivalent) in 2024. Its source EUI of 214.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,727,835 kWh of electricity, 0 therms of natural gas and 362 thousand gallons of water for the year.
Which law requires 2100 MLK to report its energy use?
2100 MLK 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 2024 disclosure (source record dc:PM4594479:2024). 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.
