How has 500 L'Enfant Plaza's energy performance changed over time?
BuildingCensus holds 3 Washington, DC disclosures for 500 L'Enfant Plaza, covering report years 2021–2023. Its ENERGY STAR score went from 80 in 2021 to 88 in 2023 (+8 points).

What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. 500 L'Enfant Plaza's 40.0 kBtu/ft² across 228,468 sq ft works out to about 9.1 billion Btu (2,678 MWh-equivalent) in 2023. Its source EUI of 112.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,679,000 kWh of electricity, 31 therms of natural gas and 100 thousand gallons of water for the year.
Which law requires 500 L'Enfant Plaza to report its energy use?
