How has 1201 Pennsylvania Ave.'s energy performance changed over time?
BuildingCensus holds 13 Washington, DC disclosures for 1201 Pennsylvania Ave., covering report years 2012–2024. Its ENERGY STAR score went from 41 in 2012 to 81 in 2024 (+40 points); its best year on file was 2021, at 84. Site EUI moved from 95.7 kBtu/ft² (2012) to 44.1 kBtu/ft² (2024), a 54% decrease. Reported emissions went from 4,607 tCO₂e to 1,951 tCO₂e over the same span (down 58%).
What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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. 1201 Pennsylvania Ave.'s 44.1 kBtu/ft² across 519,773 sq ft works out to about 22.9 billion Btu (6,718 MWh-equivalent) in 2024. Its source EUI of 117.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 6,188,795 kWh of electricity, 18,315 therms of natural gas and 6,388 thousand gallons of water for the year.
Which law requires 1201 Pennsylvania Ave. to report its energy use?
