Its site EUI of 2.2 kBtu/ft² is about 96% below the average of 56.4 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.1 kgCO₂e/ft² is about 96% below the group average of 3.6 kgCO₂e/ft².
At 185,000 sq ft, it is about 22% above the average floor area of 151,937 sq ft for those buildings. Its 1986 construction date is close to the group's average year built (1985).

What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. 2200 John Glenn Dr. Parking Garage's 2.2 kBtu/ft² across 185,000 sq ft works out to about 0.4 billion Btu (119 MWh-equivalent) in 2024. The disclosure also reports 120,982 kWh of electricity for the year.
