The latest disclosures cover 1,515 multifamily housing buildings in Chicago, out of 3,852 buildings citywide. Surf II LLC's ENERGY STAR score of 85 compares with an average of 62 across the 1,472 that report a score; it scores higher than 73% of them and lower than 25%. Its site EUI of 67.2 kBtu/ft² is roughly in line with the average of 72.0 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.8 kgCO₂e/ft² is about 17% below the group average of 5.8 kgCO₂e/ft².

At 56,500 sq ft, it is about 73% below the average floor area of 206,097 sq ft for those buildings. It was built in 1933, 38 years earlier than the group's average year built (1971). Across all 24 jurisdictions BuildingCensus covers, the 59,945 multifamily housing buildings average an ENERGY STAR score of 70 and a site EUI of 59.0 kBtu/ft².

How has Surf II LLC's energy performance changed over time?

BuildingCensus holds 8 Chicago disclosures for Surf II LLC, covering report years 2016–2023. Its ENERGY STAR score went from 90 in 2016 to 85 in 2023 (-5 points); its best year on file was 2016, at 90. Site EUI moved from 62.6 kBtu/ft² (2016) to 67.2 kBtu/ft² (2023), an 7% increase. Reported emissions went from 313 tCO₂e to 269 tCO₂e over the same span (down 14%).

What does an ENERGY STAR score of 85 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 85 means the building performs better than about 85% of its national peers. BuildingCensus bands the score into report-card grades; 85 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 Chicago, 35% 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. Surf II LLC's 67.2 kBtu/ft² across 56,500 sq ft works out to about 3.8 billion Btu (1,113 MWh-equivalent) in 2023. Its source EUI of 94.5 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 226,190 kWh of electricity and 30,259 therms of natural gas for the year.

Which law requires Surf II LLC to report its energy use?

Surf II LLC reports under the Building Energy Use Benchmarking Ordinance, the legal basis of the Chicago Energy Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2023 disclosure (source record chicago:253905:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
