How does Hilton Garden Inn compare with other hotel buildings in California?
The latest disclosures cover 1,599 hotel buildings in California, out of 40,029 buildings citywide. Hilton Garden Inn's ENERGY STAR score of 97 compares with an average of 74 across the 1,525 that report a score; it scores higher than 82% of them and lower than 15%. Its site EUI of 33.4 kBtu/ft² is about half of 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 2.2 kgCO₂e/ft² is about half of the group average of 4.0 kgCO₂e/ft².
At 63,206 sq ft, it is about 62% below the average floor area of 167,786 sq ft for those buildings. It was built in 2008, 20 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.
What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. Hilton Garden Inn's 33.4 kBtu/ft² across 63,206 sq ft works out to about 2.1 billion Btu (619 MWh-equivalent) in 2019. The disclosure also reports 615,821 kWh of electricity for the year.
Which law requires Hilton Garden Inn to report its energy use?
Hilton Garden Inn 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 2019 disclosure (source record california:6832788:2019). 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.
