How has The Martin - Greystar's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for The Martin - Greystar, covering report years 2018–2025. Its ENERGY STAR score went from 92 in 2018 to 97 in 2025 (+5 points); its best year on file was 2024, at 97. Site EUI moved from 39.1 kBtu/ft² (2018) to 23.3 kBtu/ft² (2025), a 40% decrease. Reported emissions went from 168 tCO₂e to 138 tCO₂e over the same span (down 18%).
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. The Martin - Greystar's 23.3 kBtu/ft² across 107,075 sq ft works out to about 2.5 billion Btu (731 MWh-equivalent) in 2025. Its source EUI of 47.4 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 412,006 kWh of electricity and 10,878 therms of natural gas for the year.
Which law requires The Martin - Greystar to report its energy use?
The Martin - Greystar 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:3994/084:2025).
