The latest disclosures cover 1,599 hotel buildings in California, out of 40,029 buildings citywide. Santa Ana Ca Cy's ENERGY STAR score of 87 compares with an average of 74 across the 1,525 that report a score; it scores higher than 57% of them and lower than 41%. Its site EUI of 61.9 kBtu/ft² is roughly in line with the average of 65.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 3.7 kgCO₂e/ft² is roughly in line with the group average of 4.0 kgCO₂e/ft².
At 90,255 sq ft, it is about half of the average floor area of 167,786 sq ft for those buildings. It was built in 2011, 23 years later than the group's average year built (1988). Across all 24 jurisdictions BuildingCensus covers, the 3,812 hotel buildings average an ENERGY STAR score of 65 and a site EUI of 77.8 kBtu/ft².
How has Santa Ana Ca Cy's energy performance changed over time?
BuildingCensus holds 7 California disclosures for Santa Ana Ca Cy, covering report years 2018–2024. Its ENERGY STAR score went from 71 in 2018 to 87 in 2024 (+16 points); its best year on file was 2020, at 90. Site EUI moved from 75.7 kBtu/ft² (2018) to 61.9 kBtu/ft² (2024), a 18% decrease. Reported emissions went from 423 tCO₂e to 331 tCO₂e over the same span (down 22%).
What does an ENERGY STAR score of 87 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 87 means the building performs better than about 87% of its national peers. BuildingCensus bands the score into report-card grades; 87 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. Santa Ana Ca Cy's 61.9 kBtu/ft² across 90,255 sq ft works out to about 5.6 billion Btu (1,637 MWh-equivalent) in 2024. The disclosure also reports 849,396 kWh of electricity and 26,157 therms of natural gas for the year.
Which law requires Santa Ana Ca Cy to report its energy use?
