What does an ENERGY STAR score of 67 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 67 means the building performs better than about 67% of its national peers. BuildingCensus bands the score into report-card grades; 67 falls in band C — below median (55–69). It sits 8 points below 75, the threshold for ENERGY STAR certification. In San Francisco, 73% 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. 1028 Market Street's 51.8 kBtu/ft² across 118,991 sq ft works out to about 6.2 billion Btu (1,806 MWh-equivalent) in 2025. Its source EUI of 105.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,007,939 kWh of electricity and 27,261 therms of natural gas for the year.
