Its ENERGY STAR score went from 95 in 2016 to 87 in 2025 (-8 points); its best year on file was 2017, at 96. Site EUI moved from 38.0 kBtu/ft² (2016) to 28.3 kBtu/ft² (2025), a 26% decrease. Reported emissions went from 3,460 tCO₂e to 1,737 tCO₂e over the same span (down 50%).
What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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 Los Angeles, 63% 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. 444 S FLOWER ST's 28.3 kBtu/ft² across 1,081,894 sq ft works out to about 30.6 billion Btu (8,973 MWh-equivalent) in 2025. Its source EUI of 74.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 7,791 thousand gallons of water for the year.
