Its ENERGY STAR score went from 97 in 2019 to 95 in 2024 (-2 points); its best year on file was 2023, at 98. Site EUI moved from 40.2 kBtu/ft² (2019) to 39.2 kBtu/ft² (2024), a 2% decrease. Reported emissions went from 354 tCO₂e to 335 tCO₂e over the same span (down 5%).

What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. Parkside - 29168's 39.2 kBtu/ft² across 147,014 sq ft works out to about 5.8 billion Btu (1,689 MWh-equivalent) in 2024. The disclosure also reports 697,852 kWh of electricity and 33,350 therms of natural gas for the year.
