National Center for International Schools

How does National Center for International Schools compare with other commercial buildings in San Francisco?

The latest disclosures cover 1,683 commercial buildings in San Francisco, out of 2,509 buildings citywide. National Center for International Schools's ENERGY STAR score of 97 compares with an average of 78 across the 790 that report a score; it scores higher than 79% of them and lower than 18%. Its site EUI of 25.6 kBtu/ft² is about half of the average of 49.2 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.3 kgCO₂e/ft² is about half of the group average of 2.7 kgCO₂e/ft².

At 211,425 sq ft, it is about twice the average floor area of 107,408 sq ft for those buildings. It was built in 1948, 7 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 National Center for International Schools's energy performance changed over time?

BuildingCensus holds 15 San Francisco disclosures for National Center for International Schools, covering report years 2011–2025. Its ENERGY STAR score went from 86 in 2011 to 97 in 2025 (+11 points); its best year on file was 2017, at 98. Site EUI moved from 37.3 kBtu/ft² (2011) to 25.6 kBtu/ft² (2025), a 31% decrease. Reported emissions went from 549 tCO₂e to 264 tCO₂e over the same span (down 52%).

What does an ENERGY STAR score of 97 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 97 means the building performs better than about 97% of its national peers. BuildingCensus bands the score into report-card grades; 97 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. National Center for International Schools's 25.6 kBtu/ft² across 211,425 sq ft works out to about 5.4 billion Btu (1,586 MWh-equivalent) in 2025. Its source EUI of 40.6 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 490,746 kWh of electricity and 31,602 therms of natural gas for the year.

Which law requires National Center for International Schools to report its energy use?

National Center for International Schools 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:0833/003:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
