Its site EUI of 64.7 kBtu/ft² is about 27% above the average of 51.1 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 4.0 kgCO₂e/ft² is roughly in line with the group average of 3.8 kgCO₂e/ft².
At 42,792 sq ft, it is about 69% below the average floor area of 136,346 sq ft for those buildings. It was built in 1923, 42 years earlier than the group's average year built (1965).

How has The Shelburne's energy performance changed over time?
BuildingCensus holds 3 Washington, DC disclosures for The Shelburne, covering report years 2022–2024. Its ENERGY STAR score went from 92 in 2022 to 90 in 2024 (-2 points); its best year on file was 2022, at 92. Site EUI moved from 64.9 kBtu/ft² (2022) to 64.7 kBtu/ft² (2024), a 0% decrease. Reported emissions went from 169 tCO₂e to 170 tCO₂e over the same span (up 1%).
What does an ENERGY STAR score of 90 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 90 means the building performs better than about 90% of its national peers. BuildingCensus bands the score into report-card grades; 90 falls in band A — high performer (85–100). 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. The Shelburne's 64.7 kBtu/ft² across 42,792 sq ft works out to about 2.8 billion Btu (811 MWh-equivalent) in 2024. Its source EUI of 95.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 193,811 kWh of electricity, 21,089 therms of natural gas and 1,552 thousand gallons of water for the year.
Which law requires The Shelburne to report its energy use?
