How has 1818 N St's energy performance changed over time?
BuildingCensus holds 12 Washington, DC disclosures for 1818 N St, covering report years 2013–2024. Its ENERGY STAR score went from 76 in 2013 to 84 in 2024 (+8 points); its best year on file was 2016, at 87. Site EUI moved from 66.9 kBtu/ft² (2013) to 34.6 kBtu/ft² (2024), a 48% decrease. Reported emissions went from 917 tCO₂e to 347 tCO₂e over the same span (down 62%).
What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. 1818 N St's 34.6 kBtu/ft² across 114,251 sq ft works out to about 4 billion Btu (1,159 MWh-equivalent) in 2024. Its source EUI of 96.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,157,904 kWh of electricity, 0 therms of natural gas and 774 thousand gallons of water for the year.
Which law requires 1818 N St to report its energy use?
1818 N St 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:PM2364583:2024). 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.
