Collection 14 (cl402)

How does Collection 14 (cl402) compare with other multifamily housing buildings in Washington, DC?

The latest disclosures cover 1,799 multifamily housing buildings in Washington, DC, out of 6,870 buildings citywide. Collection 14 (cl402)'s ENERGY STAR score of 92 compares with an average of 72 across the 1,618 that report a score; it scores higher than 74% of them and lower than 24%. Its site EUI of 39.2 kBtu/ft² is about 23% below 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 3.0 kgCO₂e/ft² is about 21% below the group average of 3.8 kgCO₂e/ft².

At 229,545 sq ft, it is about 68% above the average floor area of 136,346 sq ft for those buildings. It was built in 2022, 57 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.

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Collection 14 (cl402)'s 39.2 kBtu/ft² across 229,545 sq ft works out to about 9 billion Btu (2,637 MWh-equivalent) in 2024. Its source EUI of 88.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,812,495 kWh of electricity, 28,212 therms of natural gas and 4,955 thousand gallons of water for the year.

Which law requires Collection 14 (cl402) to report its energy use?

Collection 14 (cl402) 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:PM35963789:2024). 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.
