Advocate South Suburban Hospital, part of the Advocate Southland Health Network, is an acute-care facility providing a wide range of comprehensive inpatient, outpatient, diagnostic and ambulatory medical services.
Starting early in the design process, the planning and design team from Advocate South Suburban enrolled the project in the ComEd® Energy Efficiency Program new construction offering, to get recommendations from our technical team and to maximize the energy savings and receive incentives.
The ComEd team worked to identify low-risk, cost-effective, energy efficiency strategies that go beyond minimum code requirements. The team used energy models to evaluate each strategy and present owners and designers with a customized incentive offer that accelerated return on investment for the energy efficiency measures. This Performance Path approach is available for new construction and major renovation projects that are early in the design process to maximize opportunities that enable the incorporation of high-performance design strategies.
Advocate South Suburban Hospital project consisted of expanding their existing building to include 97,600 ft2 of area.
The project included two new air-cooled chillers and a steam forced draft boiler located in the central plant. The new building’s HVAC system was tied to the hospital’s central plant to optimize the usage of the existing energy efficient water-cooled chiller, reduce the redundancy and improve the new building’s infrastructure. The air handling unit (AHU) serving operating rooms has a dedicated outdoor air system (DOAS) unit with desiccant wheel for dehumidification.
The project installed the following list of energy conservation measures:
Advocate South Suburban Hospital qualified for the Performance Pathway and received $84,500* in total incentives from ComEd. The 97,600 ft2 addition project in Hazel Crest reduced their estimated energy costs by $62,100** annually.
