What does an ENERGY STAR score of 34 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 34 means the building performs better than about 34% of its national peers. BuildingCensus bands the score into report-card grades; 34 falls in band D — lowest band (1–54). It sits 41 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. Miriwa Center Office Condos's 59.8 kBtu/ft² across 46,879 sq ft works out to about 2.8 billion Btu (822 MWh-equivalent) in 2025. Its source EUI of 167.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 817,739 kWh of electricity and 142 therms of natural gas for the year.
Which law requires Miriwa Center Office Condos to report its energy use?
Miriwa Center Office Condos reports under SF Environment Code Chapter 20, the legal basis of San Francisco's Existing Buildings Energy Performance Ordinance, which publishes each covered building's annual benchmarking results.
