Its ENERGY STAR score went from 82 in 2018 to 77 in 2024 (-5 points); its best year on file was 2019, at 83. Site EUI moved from 39.4 kBtu/ft² (2018) to 34.4 kBtu/ft² (2024), a 13% decrease.

What does an ENERGY STAR score of 77 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 77 means the building performs better than about 77% of its national peers. BuildingCensus bands the score into report-card grades; 77 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 California, 65% 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. 2 Park Plaza's 34.4 kBtu/ft² across 239,530 sq ft works out to about 8.2 billion Btu (2,415 MWh-equivalent) in 2024. The disclosure also reports 2,465,960 kWh of electricity for the year.
Which law requires 2 Park Plaza to report its energy use?
