Its site EUI of 61.4 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 3.8 kgCO₂e/ft² is roughly in line with the group average of 4.0 kgCO₂e/ft².
At 395,731 sq ft, it is about 136% above the average floor area of 167,786 sq ft for those buildings. Its 1987 construction date is close to the group's average year built (1988).

What does an ENERGY STAR score of 79 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 79 means the building performs better than about 79% of its national peers. BuildingCensus bands the score into report-card grades; 79 falls in band B — above median (70–84). 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. Westin San Diego Gaslamp Quarter's 61.4 kBtu/ft² across 395,731 sq ft works out to about 24.3 billion Btu (7,121 MWh-equivalent) in 2022. The disclosure also reports 3,999,555 kWh of electricity and 108,329 therms of natural gas for the year.
