How has 8 Potomac LLC's energy performance changed over time?

Its ENERGY STAR score went from 65 in 2022 to 82 in 2024 (+17 points); its best year on file was 2023, at 85. Site EUI moved from 42.6 kBtu/ft² (2022) to 36.0 kBtu/ft² (2024), a 15% decrease. Reported emissions went from 92 tCO₂e to 80 tCO₂e over the same span (down 14%).
What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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. 8 Potomac LLC's 36.0 kBtu/ft² across 29,191 sq ft works out to about 1.1 billion Btu (308 MWh-equivalent) in 2024. Its source EUI of 79.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 201,264 kWh of electricity, 3,645 therms of natural gas and 106 thousand gallons of water for the year.
