The Promenade

How does The Promenade 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. The Promenade's ENERGY STAR score of 95 compares with an average of 72 across the 1,618 that report a score; it scores higher than 82% of them and lower than 16%. Its site EUI of 41.4 kBtu/ft² is about 19% 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 2.8 kgCO₂e/ft² is about 26% below the group average of 3.8 kgCO₂e/ft².

At 206,478 sq ft, it is about 51% above the average floor area of 136,346 sq ft for those buildings. Its 1965 construction date is close to 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 The Promenade's energy performance changed over time?

BuildingCensus holds 13 Washington, DC disclosures for The Promenade, covering report years 2012–2024. Its ENERGY STAR score went from 85 in 2014 to 95 in 2024 (+10 points); its best year on file was 2016, at 95. Site EUI moved from 57.0 kBtu/ft² (2012) to 41.4 kBtu/ft² (2024), a 27% decrease. Reported emissions went from 1,070 tCO₂e to 580 tCO₂e over the same span (down 46%).

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. The Promenade's 41.4 kBtu/ft² across 206,478 sq ft works out to about 8.5 billion Btu (2,505 MWh-equivalent) in 2024. Its source EUI of 73.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,043,536 kWh of electricity, 49,112 therms of natural gas and 6,813 thousand gallons of water for the year.

Which law requires The Promenade to report its energy use?

The Promenade 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:PM3075531:2024). 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.
