Its ENERGY STAR score went from 43 in 2019 to 81 in 2024 (+38 points); its best year on file was 2022, at 89. Site EUI moved from 56.5 kBtu/ft² (2019) to 38.0 kBtu/ft² (2024), a 33% decrease.

What does an ENERGY STAR score of 81 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 81 means the building performs better than about 81% of its national peers. BuildingCensus bands the score into report-card grades; 81 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. 399 Fremont's 38.0 kBtu/ft² across 509,885 sq ft works out to about 19.4 billion Btu (5,678 MWh-equivalent) in 2024. The disclosure also reports 2,842,187 kWh of electricity and 98,366 therms of natural gas for the year.
