Casa De Maestro's ENERGY STAR score of 61 compares with an average of 82 across the 9,612 that report a score; it scores higher than 15% of them and lower than 85%. Its site EUI of 46.9 kBtu/ft² is about 36% above the average of 34.4 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 2.9 kgCO₂e/ft² is about 38% above the group average of 2.1 kgCO₂e/ft².
At 15,500 sq ft, it is about 90% below the average floor area of 150,919 sq ft for those buildings. It was built in 2001, 13 years later than the group's average year built (1988).

What does an ENERGY STAR score of 61 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 61 means the building performs better than about 61% of its national peers. BuildingCensus bands the score into report-card grades; 61 falls in band C — below median (55–69). It sits 14 points below 75, the threshold for ENERGY STAR certification. 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. Casa De Maestro's 46.9 kBtu/ft² across 15,500 sq ft works out to about 0.7 billion Btu (213 MWh-equivalent) in 2023. The disclosure also reports 92,709 kWh of electricity and 4,237 therms of natural gas for the year.
Which law requires Casa De Maestro to report its energy use?
Casa De Maestro reports under AB 802 (Public Resources Code §25402.10), the legal basis of California's Building Energy Benchmarking Program (statewide), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record california:34545957:2023).
