Its site EUI of 67.2 kBtu/ft² is about 15% below the average of 78.7 kBtu/ft² — it uses less energy per square foot than the typical building in that group.
At 61,114 sq ft, it is about half of the average floor area of 121,167 sq ft for those buildings. It was built in 1918, 47 years earlier than the group's average year built (1965). 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 58 Charles Street's energy performance changed over time?
BuildingCensus holds 10 Cambridge disclosures for 58 Charles Street, covering report years 2015–2024. Its ENERGY STAR score went from 94 in 2015 to 69 in 2024 (-25 points); its best year on file was 2021, at 100. Site EUI moved from 48.2 kBtu/ft² (2015) to 67.2 kBtu/ft² (2024), an 39% increase. Reported emissions went from 187 tCO₂e to 281 tCO₂e over the same span (up 51%).
What does an ENERGY STAR score of 69 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 69 means the building performs better than about 69% of its national peers. BuildingCensus bands the score into report-card grades; 69 falls in band C — below median (55–69). It sits 6 points below 75, the threshold for ENERGY STAR certification. In Cambridge, 50% 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. 58 Charles Street's 67.2 kBtu/ft² across 61,114 sq ft works out to about 4.1 billion Btu (1,204 MWh-equivalent) in 2024. Its source EUI of 164.9 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 965,564 kWh of electricity, 8,116 therms of natural gas and 179 thousand gallons of water for the year.
Which law requires 58 Charles Street to report its energy use?
58 Charles Street reports under BEUDO, the legal basis of Cambridge's Building Energy Use Disclosure Ordinance (BEUDO), which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2024 disclosure (source record cambridge:B1594:2024). Cambridge's 2023 BEUDO amendments require non-residential buildings of 100,000+ sq ft to reach net-zero emissions by 2035 (reductions starting 2026) and those of 25,000–100,000 sq ft by 2050 (starting 2030).
