Its ENERGY STAR score went from 100 in 2017 to 91 in 2019 (-9 points); its best year on file was 2017, at 100. Site EUI moved from 34.4 kBtu/ft² (2017) to 54.4 kBtu/ft² (2019), an 58% increase. Reported emissions went from 640 tCO₂e to 959 tCO₂e over the same span (up 50%).
What does an ENERGY STAR score of 91 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 91 means the building performs better than about 91% of its national peers. BuildingCensus bands the score into report-card grades; 91 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. Tilden Gardens's 54.4 kBtu/ft² across 264,773 sq ft works out to about 14.4 billion Btu (4,221 MWh-equivalent) in 2019. Its source EUI of 87.3 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,337,190 kWh of electricity, 98,398 therms of natural gas and 3,574 thousand gallons of water for the year.
