How has Buckingham Apartments's energy performance changed over time?

What does an ENERGY STAR score of 96 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 96 means the building performs better than about 96% of its national peers. BuildingCensus bands the score into report-card grades; 96 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. Buckingham Apartments's 26.5 kBtu/ft² across 99,741 sq ft works out to about 2.6 billion Btu (775 MWh-equivalent) in 2024. The disclosure also reports 367,813 kWh of electricity and 13,227 therms of natural gas for the year.
