How has Azure Apartments's energy performance changed over time?
BuildingCensus holds 8 San Francisco disclosures for Azure Apartments, covering report years 2018–2025. Its ENERGY STAR score went from 63 in 2018 to 70 in 2025 (+7 points). Site EUI moved from 39.0 kBtu/ft² (2018) to 35.4 kBtu/ft² (2025), a 9% decrease. Reported emissions went from 802 tCO₂e to 639 tCO₂e over the same span (down 20%).
What does an ENERGY STAR score of 70 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 70 means the building performs better than about 70% of its national peers. BuildingCensus bands the score into report-card grades; 70 falls in band B — above median (70–84). It sits 5 points below 75, the threshold for ENERGY STAR certification. 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. Azure Apartments's 35.4 kBtu/ft² across 399,838 sq ft works out to about 14.2 billion Btu (4,148 MWh-equivalent) in 2025. Its source EUI of 80.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,339,764 kWh of electricity and 34,433 therms of natural gas for the year.
Which law requires Azure Apartments to report its energy use?
Azure Apartments 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:8711/228:2025).
