Carter Terrace

How does Carter Terrace compare with other mixed residential buildings in San Francisco?

The latest disclosures cover 610 mixed residential buildings in San Francisco, out of 2,509 buildings citywide. Carter Terrace's ENERGY STAR score of 99 compares with an average of 85 across the 340 that report a score; it scores higher than 62% of them and lower than 31%. Its site EUI of 35.5 kBtu/ft² is roughly in line with the average of 36.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 1.9 kgCO₂e/ft² is roughly in line with the group average of 2.0 kgCO₂e/ft².

At 100,000 sq ft, it is about 40% below the average floor area of 165,572 sq ft for those buildings. It was built in 2004, 38 years later than the group's average year built (1967).

How has Carter Terrace's energy performance changed over time?

BuildingCensus holds 8 San Francisco disclosures for Carter Terrace, covering report years 2018–2025. Its ENERGY STAR score went from 100 in 2018 to 99 in 2025 (-1 points); its best year on file was 2018, at 100. Site EUI moved from 22.8 kBtu/ft² (2018) to 35.5 kBtu/ft² (2025), an 56% increase. Reported emissions went from 135 tCO₂e to 193 tCO₂e over the same span (up 43%).

What does an ENERGY STAR score of 99 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 99 means the building performs better than about 99% of its national peers. BuildingCensus bands the score into report-card grades; 99 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. Carter Terrace's 35.5 kBtu/ft² across 100,000 sq ft works out to about 3.6 billion Btu (1,040 MWh-equivalent) in 2025. Its source EUI of 56.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 329,730 kWh of electricity and 24,209 therms of natural gas for the year.

Which law requires Carter Terrace to report its energy use?

Carter Terrace 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:6428/008:2025). San Francisco's ordinance requires annual benchmarking for commercial buildings over 10,000 sq ft, with administrative penalties for buildings that fail to report.
