How does The Opal Hotel compare with other hotel buildings in California?
The latest disclosures cover 1,599 hotel buildings in California, out of 40,029 buildings citywide. The Opal Hotel's ENERGY STAR score of 88 compares with an average of 74 across the 1,525 that report a score; it scores higher than 59% of them and lower than 39%. 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 3.6 kgCO₂e/ft² is about 10% below the group average of 4.0 kgCO₂e/ft².
At 93,500 sq ft, it is about 44% below the average floor area of 167,786 sq ft for those buildings. It was built in 1908, 80 years earlier 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 The Opal Hotel's energy performance changed over time?
BuildingCensus holds 7 California disclosures for The Opal Hotel, covering report years 2018–2024. Its ENERGY STAR score went from 98 in 2018 to 88 in 2024 (-10 points); its best year on file was 2021, at 100. Site EUI moved from 45.1 kBtu/ft² (2018) to 61.9 kBtu/ft² (2024), an 37% increase. Reported emissions went from 252 tCO₂e to 336 tCO₂e over the same span (up 33%).
What does an ENERGY STAR score of 88 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 88 means the building performs better than about 88% of its national peers. BuildingCensus bands the score into report-card grades; 88 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. The Opal Hotel's 61.9 kBtu/ft² across 93,500 sq ft works out to about 5.8 billion Btu (1,696 MWh-equivalent) in 2024. The disclosure also reports 628,138 kWh of electricity and 36,505 therms of natural gas for the year.
Which law requires The Opal Hotel to report its energy use?
The Opal Hotel 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 2024 disclosure (source record california:4354700:2024). AB 802 requires every California commercial building over 50,000 sq ft to report energy use to the CEC annually; the CEC publicly discloses the results statewide.
