Madison Place Apartments's ENERGY STAR score of 92 compares with an average of 82 across the 9,612 that report a score; it scores higher than 51% of them and lower than 47%. Its site EUI of 40.6 kBtu/ft² is about 18% above the average of 34.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group.

At 48,596 sq ft, it is about 68% below the average floor area of 150,919 sq ft for those buildings. It was built in 1964, 24 years earlier than the group's average year built (1988).

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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. Madison Place Apartments's 40.6 kBtu/ft² across 48,596 sq ft works out to about 2 billion Btu (578 MWh-equivalent) in 2023. The disclosure also reports 179,205 kWh of electricity and 13,841 therms of natural gas for the year.
