Hotel Nikko's ENERGY STAR score of 95 compares with an average of 78 across the 790 that report a score; it scores higher than 73% of them and lower than 24%. Its site EUI of 58.3 kBtu/ft² is about 18% above the average of 49.2 kBtu/ft² — it uses more energy per square foot than the typical building in that group. Its emissions intensity of 3.2 kgCO₂e/ft² is about 18% above the group average of 2.7 kgCO₂e/ft².
At 626,909 sq ft, it is about 484% above the average floor area of 107,408 sq ft for those buildings. It was built in 1988, 47 years later than the group's average year built (1941). Across all 24 jurisdictions BuildingCensus covers, the 2,307 commercial buildings average an ENERGY STAR score of 76 and a site EUI of 51.3 kBtu/ft².
How has Hotel Nikko's energy performance changed over time?
BuildingCensus holds 15 San Francisco disclosures for Hotel Nikko, covering report years 2011–2025. Its ENERGY STAR score went from 81 in 2011 to 95 in 2025 (+14 points). Site EUI moved from 61.9 kBtu/ft² (2011) to 58.3 kBtu/ft² (2025), a 6% decrease. Reported emissions went from 3,416 tCO₂e to 1,804 tCO₂e over the same span (down 47%).
What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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 Nikko's 58.3 kBtu/ft² across 626,909 sq ft works out to about 36.5 billion Btu (10,711 MWh-equivalent) in 2025. Its source EUI of 101.0 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 3,776,170 kWh of electricity and 200,111 therms of natural gas for the year.
Which law requires Hotel Nikko to report its energy use?
Hotel Nikko 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:0326/011:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
