American Chemical Society - Headquarters's ENERGY STAR score of 78 compares with an average of 70 across the 774 that report a score; it scores higher than 56% of them and lower than 41%. Its site EUI of 64.1 kBtu/ft² is about 15% above the average of 55.6 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 4.7 kgCO₂e/ft² is roughly in line with the group average of 5.0 kgCO₂e/ft².

At 115,470 sq ft, it is about half of the average floor area of 216,135 sq ft for those buildings. It was built in 1959, 15 years earlier 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 American Chemical Society - Headquarters's energy performance changed over time?

Its ENERGY STAR score went from 88 in 2013 to 78 in 2024 (-10 points); its best year on file was 2014, at 89. Site EUI moved from 107.6 kBtu/ft² (2013) to 64.1 kBtu/ft² (2024), a 40% decrease. Reported emissions went from 1,374 tCO₂e to 542 tCO₂e over the same span (down 61%).

What does an ENERGY STAR score of 78 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 78 means the building performs better than about 78% of its national peers. BuildingCensus bands the score into report-card grades; 78 falls in band B — above median (70–84). 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. American Chemical Society - Headquarters's 64.1 kBtu/ft² across 115,470 sq ft works out to about 7.4 billion Btu (2,169 MWh-equivalent) in 2024. Its source EUI of 132.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,257,194 kWh of electricity, 31,134 therms of natural gas and 1,332 thousand gallons of water for the year.

Which law requires American Chemical Society - Headquarters to report its energy use?

American Chemical Society - Headquarters 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:PM1034322:2024). 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.
