The latest disclosures cover 1,799 multifamily housing buildings in Washington, DC, out of 6,870 buildings citywide. 1331 (bo030)'s ENERGY STAR score of 54 compares with an average of 72 across the 1,618 that report a score; it scores higher than 21% of them and lower than 78%. Its site EUI of 48.8 kBtu/ft² is roughly in line with 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 3.7 kgCO₂e/ft² is roughly in line with the group average of 3.8 kgCO₂e/ft².

At 483,327 sq ft, it is about 254% above the average floor area of 136,346 sq ft for those buildings. It was built in 2019, 54 years later 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.

How has 1331 (bo030)'s energy performance changed over time?

BuildingCensus holds 3 Washington, DC disclosures for 1331 (bo030), covering report years 2022–2024. Its ENERGY STAR score went from 38 in 2022 to 54 in 2024 (+16 points). Site EUI moved from 61.1 kBtu/ft² (2022) to 48.8 kBtu/ft² (2024), a 20% decrease. Reported emissions went from 1,810 tCO₂e to 1,767 tCO₂e over the same span (down 2%).

What does an ENERGY STAR score of 54 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 54 means the building performs better than about 54% of its national peers. BuildingCensus bands the score into report-card grades; 54 falls in band D — lowest band (1–54). It sits 21 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. 1331 (bo030)'s 48.8 kBtu/ft² across 483,327 sq ft works out to about 23.6 billion Btu (6,912 MWh-equivalent) in 2024. Its source EUI of 104.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 4,343,808 kWh of electricity, 87,784 therms of natural gas and 9,131 thousand gallons of water for the year.

Which law requires 1331 (bo030) to report its energy use?

1331 (bo030) 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:PM16297833:2024). 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.
