How has Capitol Place I's energy performance changed over time?
BuildingCensus holds 13 Washington, DC disclosures for Capitol Place I, covering report years 2012–2024. Its ENERGY STAR score went from 49 in 2012 to 85 in 2024 (+36 points).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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. Capitol Place I's 43.3 kBtu/ft² across 149,722 sq ft works out to about 6.5 billion Btu (1,900 MWh-equivalent) in 2024. Its source EUI of 121.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,898,201 kWh of electricity, 0 therms of natural gas and 2,728 thousand gallons of water for the year.
Which law requires Capitol Place I to report its energy use?
