THE ASHLEY CONDOMINIUM's ENERGY STAR score of 94 compares with an average of 72 across the 1,618 that report a score; it scores higher than 78% of them and lower than 18%. Its site EUI of 26.0 kBtu/ft² is about half of the average of 51.1 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 2.3 kgCO₂e/ft² is about 41% below the group average of 3.8 kgCO₂e/ft².
At 42,937 sq ft, it is about 69% below the average floor area of 136,346 sq ft for those buildings. It was built in 1910, 55 years earlier than the group's average year built (1965).

How has THE ASHLEY CONDOMINIUM's energy performance changed over time?
BuildingCensus holds 3 Washington, DC disclosures for THE ASHLEY CONDOMINIUM, covering report years 2022–2024. Its ENERGY STAR score went from 91 in 2022 to 94 in 2024 (+3 points). Site EUI moved from 27.9 kBtu/ft² (2022) to 26.0 kBtu/ft² (2024), a 7% decrease. Reported emissions went from 106 tCO₂e to 97 tCO₂e over the same span (down 9%).
What does an ENERGY STAR score of 94 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 94 means the building performs better than about 94% of its national peers. BuildingCensus bands the score into report-card grades; 94 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 ASHLEY CONDOMINIUM's 26.0 kBtu/ft² across 42,937 sq ft works out to about 1.1 billion Btu (327 MWh-equivalent) in 2024. Its source EUI of 71.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 316,537 kWh of electricity, 346 therms of natural gas and 815 thousand gallons of water for the year.
Which law requires THE ASHLEY CONDOMINIUM to report its energy use?
