What does an ENERGY STAR score of 83 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 83 means the building performs better than about 83% of its national peers. BuildingCensus bands the score into report-card grades; 83 falls in band B — above median (70–84). 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 Boston, 52% 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. 110 K St's 43.3 kBtu/ft² across 40,960 sq ft works out to about 1.8 billion Btu (520 MWh-equivalent) in 2024. The disclosure also reports 261,255 kWh of electricity and 8,806 therms of natural gas for the year.

Which law requires 110 K St to report its energy use?

110 K St reports under BERDO 2.0, the legal basis of Boston's Building Emissions Reduction and Disclosure Ordinance, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record boston:104008:2024). BERDO 2.0 sets emissions standards for buildings of 20,000+ sq ft or 15+ units, starting in 2025 or 2030 depending on building size, with an alternative-compliance payment of $234 per metric ton of CO₂e over the limit.
