Its ENERGY STAR score went from 77 in 2020 to 83 in 2024 (+6 points); its best year on file was 2022, at 85. Site EUI moved from 32.1 kBtu/ft² (2020) to 30.7 kBtu/ft² (2024), a 4% decrease.

What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 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. Water'S Edge (Wt037)'s 30.7 kBtu/ft² across 173,832 sq ft works out to about 5.3 billion Btu (1,564 MWh-equivalent) in 2024. The disclosure also reports 644,019 kWh of electricity and 31,237 therms of natural gas for the year.
