Its site EUI of 57.2 kBtu/ft² is about 35% below the average of 87.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.9 kgCO₂e/ft² is about 29% below the group average of 6.9 kgCO₂e/ft².
At 133,375 sq ft, it is about 41% below the average floor area of 227,860 sq ft for those buildings. It was built in 1969, 5 years earlier than the group's average year built (1974).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Washington Courtyard by Marriott's 57.2 kBtu/ft² across 133,375 sq ft works out to about 7.6 billion Btu (2,236 MWh-equivalent) in 2018. Its source EUI of 127.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,515,720 kWh of electricity, 24,569 therms of natural gas and 3,660 thousand gallons of water for the year.
