Its site EUI of 67.4 kBtu/ft² is about 32% 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 4.3 kgCO₂e/ft² is about 14% above the group average of 3.8 kgCO₂e/ft².

At 69,694 sq ft, it is about half of the average floor area of 136,346 sq ft for those buildings. It was built in 1959, 6 years earlier than the group's average year built (1965). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 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. 2400 Pennsylvania AV NW's 67.4 kBtu/ft² across 69,694 sq ft works out to about 4.7 billion Btu (1,377 MWh-equivalent) in 2024. Its source EUI of 109.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 449,068 kWh of electricity, 31,617 therms of natural gas and 321 thousand gallons of water for the year.

Which law requires 2400 Pennsylvania AV NW to report its energy use?

2400 Pennsylvania AV NW 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:PM3980627:2024). 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.
