Its site EUI of 62.5 kBtu/ft² is about 12% above the average of 55.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 5.3 kgCO₂e/ft² is roughly in line with the group average of 5.0 kgCO₂e/ft².

At 199,050 sq ft, it is roughly in line with the average floor area of 216,135 sq ft for those buildings. It was built in 2020, 46 years later than the group's average year built (1974). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².

How has 250 M St's energy performance changed over time?

Its ENERGY STAR score went from 65 in 2023 to 63 in 2024 (-2 points); its best year on file was 2023, at 65. Site EUI moved from 59.9 kBtu/ft² (2023) to 62.5 kBtu/ft² (2024), an 4% increase. Reported emissions went from 1,016 tCO₂e to 1,053 tCO₂e over the same span (up 4%).

What does an ENERGY STAR score of 63 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 63 means the building performs better than about 63% of its national peers. BuildingCensus bands the score into report-card grades; 63 falls in band C — below median (55–69). It sits 12 points below 75, the threshold for ENERGY STAR certification. 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. 250 M St's 62.5 kBtu/ft² across 199,050 sq ft works out to about 12.4 billion Btu (3,646 MWh-equivalent) in 2024. Its source EUI of 165.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,322,551 kWh of electricity, 10,977 therms of natural gas and 4,840 thousand gallons of water for the year.

Which law requires 250 M St to report its energy use?

250 M St 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:PM19579523:2024). 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.
