The latest disclosures cover 899 office buildings in Washington, DC, out of 6,870 buildings citywide. American Public Health Association's ENERGY STAR score of 41 compares with an average of 70 across the 774 that report a score; it scores higher than 9% of them and lower than 89%. Its site EUI of 54.3 kBtu/ft² is roughly in line with 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 4.8 kgCO₂e/ft² is roughly in line with the group average of 5.0 kgCO₂e/ft².

At 46,163 sq ft, it is about 79% below the average floor area of 216,135 sq ft for those buildings. It was built in 1999, 25 years later than the group's average year built (1974).

How has American Public Health Association's energy performance changed over time?

BuildingCensus holds 8 Washington, DC disclosures for American Public Health Association, covering report years 2017–2024. Its ENERGY STAR score went from 85 in 2017 to 41 in 2024 (-44 points); its best year on file was 2017, at 85. Site EUI moved from 43.7 kBtu/ft² (2017) to 54.3 kBtu/ft² (2024), an 24% increase. Reported emissions went from 303 tCO₂e to 220 tCO₂e over the same span (down 27%).

What does an ENERGY STAR score of 41 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 41 means the building performs better than about 41% of its national peers. BuildingCensus bands the score into report-card grades; 41 falls in band D — lowest band (1–54). It sits 34 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. American Public Health Association's 54.3 kBtu/ft² across 46,163 sq ft works out to about 2.5 billion Btu (735 MWh-equivalent) in 2024. Its source EUI of 151.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 729,140 kWh of electricity, 0 therms of natural gas and 73 thousand gallons of water for the year.

Which law requires American Public Health Association to report its energy use?

American Public Health Association 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:PM6247638:2024). 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.
