How has 1600 I Street Corporation's energy performance changed over time?
BuildingCensus holds 5 Washington, DC disclosures for 1600 I Street Corporation, covering report years 2012–2016. Its ENERGY STAR score went from 79 in 2012 to 84 in 2016 (+5 points).

What does an ENERGY STAR score of 84 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 84 means the building performs better than about 84% of its national peers. BuildingCensus bands the score into report-card grades; 84 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. 1600 I Street Corporation's 87.3 kBtu/ft² across 138,872 sq ft works out to about 12.1 billion Btu (3,553 MWh-equivalent) in 2016. Its source EUI of 194.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,003,369 kWh of electricity, 52,822 therms of natural gas and 1,699 thousand gallons of water for the year.
