What does an ENERGY STAR score of 95 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 95 means the building performs better than about 95% of its national peers. BuildingCensus bands the score into report-card grades; 95 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. SPACE NEEDLE CORPORATE OFFICE- WILL BE DEMO'D's 29.6 kBtu/ft² across 21,128 sq ft works out to about 0.6 billion Btu (183 MWh-equivalent) in 2020. Its source EUI of 51.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 72,333 kWh of electricity and 3,780 therms of natural gas for the year.

Which law requires SPACE NEEDLE CORPORATE OFFICE- WILL BE DEMO'D to report its energy use?

SPACE NEEDLE CORPORATE OFFICE- WILL BE DEMO'D 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 2020 disclosure (source record seattle:21530:2020). 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.
