How does Maple Crain LLC compare with other multifamily housing buildings in Evanston?

The latest disclosures cover 172 multifamily housing buildings in Evanston, out of 366 buildings citywide. Maple Crain LLC's ENERGY STAR score of 82 compares with an average of 71 across the 149 that report a score; it scores higher than 54% of them and lower than 43%. Its site EUI of 66.6 kBtu/ft² is about 12% below the average of 75.6 kBtu/ft² — it uses less energy per square foot than the typical building in that group. Its emissions intensity of 4.3 kgCO₂e/ft² is about 25% below the group average of 5.7 kgCO₂e/ft².

At 27,012 sq ft, it is about 66% below the average floor area of 80,265 sq ft for those buildings. It was built in 1935, 14 years earlier than the group's average year built (1949). 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.

What does an ENERGY STAR score of 82 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 82 means the building performs better than about 82% of its national peers. BuildingCensus bands the score into report-card grades; 82 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 Evanston, 45% 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. Maple Crain LLC's 66.6 kBtu/ft² across 27,012 sq ft works out to about 1.8 billion Btu (527 MWh-equivalent) in 2019. Its source EUI of 82.8 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 58,207 kWh of electricity, 15,999 therms of natural gas and 96 thousand gallons of water for the year.

Which law requires Maple Crain LLC to report its energy use?

Maple Crain LLC reports under the Healthy Buildings Ordinance (1-O-25), the legal basis of Evanston's Building Energy and Water Use Benchmarking program, which publishes each covered building's annual benchmarking results. The record shown here is the report-year 2019 disclosure (source record evanston:108010:2019). Evanston's Healthy Buildings Ordinance (1-O-25) requires buildings of 20,000 sq ft or more to benchmark and report energy and water use by June 30 each year; the city says non-compliance fines of $250 per month begin January 1, 2027.
