How does 2021 The Alameda compare with other office buildings in San José?
The latest disclosures cover 408 office buildings in San José, out of 1,790 buildings citywide. 2021 The Alameda's ENERGY STAR score of 68 compares with an average of 67 across the 283 that report a score; it scores higher than 36% of them and lower than 64%. Its site EUI of 59.6 kBtu/ft² is roughly in line with the average of 64.9 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 40,324 sq ft, it is about 58% below the average floor area of 95,555 sq ft for those buildings. Its 1984 construction date is close to the group's average year built (1986). Across all 24 jurisdictions BuildingCensus covers, the 15,264 office buildings average an ENERGY STAR score of 73 and a site EUI of 59.3 kBtu/ft².
How has 2021 The Alameda's energy performance changed over time?
BuildingCensus holds 6 San José disclosures for 2021 The Alameda, covering report years 2019–2024. Its ENERGY STAR score went from 74 in 2022 to 68 in 2024 (-6 points); its best year on file was 2022, at 74. Site EUI moved from 54.0 kBtu/ft² (2022) to 59.6 kBtu/ft² (2024), an 10% increase. Reported emissions went from 138 tCO₂e to 147 tCO₂e over the same span (up 7%).
What does an ENERGY STAR score of 68 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 68 means the building performs better than about 68% of its national peers. BuildingCensus bands the score into report-card grades; 68 falls in band C — below median (55–69). It sits 7 points below 75, the threshold for ENERGY STAR certification. In San José, 69% 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. 2021 The Alameda's 59.6 kBtu/ft² across 40,324 sq ft works out to about 2.4 billion Btu (704 MWh-equivalent) in 2024. Its source EUI of 127.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 436,625 kWh of electricity, 9,139 therms of natural gas and 428 thousand gallons of water for the year.
Which law requires 2021 The Alameda to report its energy use?
2021 The Alameda reports under San José Municipal Code Ch. 17.85 (Energy and Water Building Performance Ordinance), the legal basis of San José's Energy and Water Building Performance Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record san_jose:0335-4-00:2024).
