Block 25w - Google

How does Block 25w - Google compare with other mixed use property buildings in Seattle?

The latest disclosures cover 157 mixed use property buildings in Seattle, out of 3,871 buildings citywide. Block 25w - Google's ENERGY STAR score of 92 compares with an average of 74 across the 29 that report a score; it scores higher than 69% of them and lower than 24%. Its site EUI of 42.8 kBtu/ft² is about 38% below the average of 68.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 0.6 kgCO₂e/ft² is about 60% below the group average of 1.4 kgCO₂e/ft².

At 292,926 sq ft, it is about 77% above the average floor area of 165,352 sq ft for those buildings. It was built in 2019, 51 years later than the group's average year built (1968). Across all 24 jurisdictions BuildingCensus covers, the 1,212 mixed use property buildings average an ENERGY STAR score of 69 and a site EUI of 79.8 kBtu/ft².

How has Block 25w - Google's energy performance changed over time?

BuildingCensus holds 6 Seattle disclosures for Block 25w - Google, covering report years 2020–2025. Its ENERGY STAR score went from 73 in 2020 to 92 in 2025 (+19 points). Site EUI moved from 48.8 kBtu/ft² (2020) to 42.8 kBtu/ft² (2025), a 12% decrease. Reported emissions went from 204 tCO₂e to 141 tCO₂e over the same span (down 31%).

What does an ENERGY STAR score of 92 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 92 means the building performs better than about 92% of its national peers. BuildingCensus bands the score into report-card grades; 92 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 Seattle, 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. Block 25w - Google's 42.8 kBtu/ft² across 292,926 sq ft works out to about 12.5 billion Btu (3,674 MWh-equivalent) in 2025. Its source EUI of 107.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 2,656,269 kWh of electricity and 17,120 therms of natural gas for the year.

Which law requires Block 25w - Google to report its energy use?

Block 25w - Google reports under the Seattle Energy Benchmarking Ordinance (SMC 22.920), the legal basis of Seattle's Building Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2025 disclosure (source record seattle:50640:2025). Seattle's Building Emissions Performance Standard (adopted 2023) applies to buildings over 20,000 sq ft: benchmarking verification is due 2027–2030 and initial emissions targets 2031–2035, reaching net zero by 2041–2050, with fines for non-compliance.
