Its ENERGY STAR score went from 100 in 2020 to 98 in 2022 (-2 points); its best year on file was 2020, at 100. Site EUI moved from 38.2 kBtu/ft² (2020) to 53.7 kBtu/ft² (2022), an 41% increase.

What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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 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. Hilton Parc 55 (Sfosf)'s 53.7 kBtu/ft² across 696,431 sq ft works out to about 37.4 billion Btu (10,960 MWh-equivalent) in 2022. The disclosure also reports 4,470,498 kWh of electricity and 221,393 therms of natural gas for the year.
