Cook County, IL: Energy performance

Energy Performance
Cumulative (vs. Baseline)17%
Annual (2019)3%

Better Buildings Challenge Partners strive to decrease portfolio-wide source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. Cook County's portfolio consists of 40 properties with over 160 buildings encompassing over 15 million square feet. Cook County has improved energy performance by 17% from a 2013 baseline, making progress towards a goal of 20% by 2025. Energy savings have been achieved by implementing significant energy conservation measures, lighting retrofits, and HVAC upgrades at 4 suburban courthouse campuses, 2 large corporate facilities, and 5 outlying highway maintenance facility campuses as part of an on-going energy program. ​Energy efficiency will continue to be a priority in current and future construction and retrofit projects throughout the County's portfolio of buildings. 


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. Cook County has achieved energy performance improvement of greater than 10% at 20 of its properties. There are 6 properties that have experienced an increase in Source EUI. These properties have been targeted for future energy efficiency improvements.


Property-level energy performance metrics, including EUI and percent improvement to date, are critical to track progress over time and identify opportunities for additional energy savings. Cook County's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 100 to 300 kBtu/sq. ft. The majority of properties have shown energy improvement since 2013. The properties located near or below the 0% axis may present good opportunities for further savings.
