Its site EUI of 34.1 kBtu/ft² is about 39% below the average of 55.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.0 kgCO₂e/ft² is about 40% below the group average of 5.0 kgCO₂e/ft².

At 300,748 sq ft, it is about 39% above the average floor area of 216,135 sq ft for those buildings. It was built in 1987, 13 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 2001 M Street's energy performance changed over time?

BuildingCensus holds 11 Washington, DC disclosures for 2001 M Street, covering report years 2012, 2013, 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024. Its ENERGY STAR score went from 98 in 2017 to 88 in 2024 (-10 points); its best year on file was 2017, at 98. Site EUI moved from 16.2 kBtu/ft² (2013) to 34.1 kBtu/ft² (2024), an 110% increase. Reported emissions went from 506 tCO₂e to 900 tCO₂e over the same span (up 78%).

What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 2001 M Street's 34.1 kBtu/ft² across 300,748 sq ft works out to about 10.3 billion Btu (3,006 MWh-equivalent) in 2024. Its source EUI of 95.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,000,341 kWh of electricity, 0 therms of natural gas and 2,491 thousand gallons of water for the year.

Which law requires 2001 M Street to report its energy use?

2001 M Street 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:PM1071901:2024). 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.
