How has Hotel Monaco San Francisco's energy performance changed over time?

Its ENERGY STAR score went from 15 in 2011 to 89 in 2025 (+74 points); its best year on file was 2021, at 93. Site EUI moved from 106.7 kBtu/ft² (2011) to 58.8 kBtu/ft² (2025), a 45% decrease. Reported emissions went from 1,286 tCO₂e to 631 tCO₂e over the same span (down 51%).
What does an ENERGY STAR score of 89 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 89 means the building performs better than about 89% of its national peers. BuildingCensus bands the score into report-card grades; 89 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 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. Hotel Monaco San Francisco's 58.8 kBtu/ft² across 176,944 sq ft works out to about 10.4 billion Btu (3,049 MWh-equivalent) in 2025. Its source EUI of 105.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 1,174,952 kWh of electricity and 17,346 therms of natural gas for the year.
Which law requires Hotel Monaco San Francisco to report its energy use?
Hotel Monaco San Francisco 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. The record shown here is the report-year 2025 disclosure (source record sf:0317/001:2025).
