Parthenia Street Senior Housing's ENERGY STAR score of 93 compares with an average of 82 across the 9,612 that report a score; it scores higher than 53% of them and lower than 45%. Its site EUI of 29.4 kBtu/ft² is about 15% below the average of 34.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.8 kgCO₂e/ft² is about 14% below the group average of 2.1 kgCO₂e/ft².
At 53,615 sq ft, it is about 64% below the average floor area of 150,919 sq ft for those buildings. It was built in 2007, 19 years later than the group's average year built (1988).

What does an ENERGY STAR score of 93 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 93 means the building performs better than about 93% of its national peers. BuildingCensus bands the score into report-card grades; 93 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. Parthenia Street Senior Housing's 29.4 kBtu/ft² across 53,615 sq ft works out to about 1.6 billion Btu (462 MWh-equivalent) in 2019. The disclosure also reports 288,342 kWh of electricity and 5,886 therms of natural gas for the year.
