How has Hotel Isabel's energy performance changed over time?
BuildingCensus holds 6 California disclosures for Hotel Isabel, covering report years 2019–2024. Its ENERGY STAR score went from 14 in 2019 to 20 in 2024 (+6 points).

What does an ENERGY STAR score of 20 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 20 means the building performs better than about 20% of its national peers. BuildingCensus bands the score into report-card grades; 20 falls in band D — lowest band (1–54). It sits 55 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. Hotel Isabel's 42.2 kBtu/ft² across 94,429 sq ft works out to about 4 billion Btu (1,168 MWh-equivalent) in 2024. The disclosure also reports 323,322 kWh of electricity and 29,110 therms of natural gas for the year.
