How has Blue Moon Lofts's energy performance changed over time?
BuildingCensus holds 7 Chicago disclosures for Blue Moon Lofts, covering report years 2016–2022. Its ENERGY STAR score went from 81 in 2016 to 100 in 2022 (+19 points); its best year on file was 2017, at 100. Site EUI moved from 36.5 kBtu/ft² (2016) to 29.7 kBtu/ft² (2022), a 19% decrease. Reported emissions went from 804 tCO₂e to 261 tCO₂e over the same span (down 67%).
What does an ENERGY STAR score of 100 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: 100 is the top of the scale. BuildingCensus bands the score into report-card grades; 100 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. Blue Moon Lofts's 29.7 kBtu/ft² across 83,000 sq ft works out to about 2.5 billion Btu (722 MWh-equivalent) in 2022. Its source EUI of 66.2 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 485,717 kWh of electricity and 8,114 therms of natural gas for the year.
Which law requires Blue Moon Lofts to report its energy use?
Blue Moon Lofts 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 2022 disclosure (source record chicago:254073:2022). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
