How has Moser Building Condominium Association's energy performance changed over time?
BuildingCensus holds 8 Chicago disclosures for Moser Building Condominium Association, covering report years 2016–2023. Its ENERGY STAR score went from 97 in 2016 to 98 in 2023 (+1 points); its best year on file was 2019, at 99. Site EUI moved from 37.2 kBtu/ft² (2016) to 37.4 kBtu/ft² (2023), an 1% increase. Reported emissions went from 604 tCO₂e to 451 tCO₂e over the same span (down 25%).
What does an ENERGY STAR score of 98 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 98 means the building performs better than about 98% of its national peers. BuildingCensus bands the score into report-card grades; 98 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. Moser Building Condominium Association's 37.4 kBtu/ft² across 144,649 sq ft works out to about 5.4 billion Btu (1,585 MWh-equivalent) in 2023. Its source EUI of 62.1 kBtu/ft² also counts the energy lost generating and delivering that power, which is why it is higher. The disclosure also reports 553,070 kWh of electricity and 35,178 therms of natural gas for the year.
Which law requires Moser Building Condominium Association to report its energy use?
Moser Building Condominium Association 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:253962:2023). Covered buildings that fail to benchmark and report face fines of up to $100 plus $25 per day of violation under the ordinance.
