The Retrofit
Twenty-two HLR (HVAC Load Reduction) modules were installed and commissioned at 155 North Wacker Drive, a 1.2-million-square- foot, 46-story office building. The project is the first HLR technology deployment in the metropolitan Chicago area.
HLR technology enables immediate capital-cost savings on new HVAC systems and provides up to 40 percent energy savings and improved indoor air quality in buildings. For 155 North Wacker, HLR modules will provide the desired IAQ while reducing energy costs by removing unwanted indoor air contaminants without requiring wholesale replacement of indoor air, which is a very energy-intensive process. The 155 North Wacker project was supported by incentives from the ComEd Energy Efficiency Program’s Emerging Technologies team, which will also be performing an energy-savings analysis to better understand how this technology could help other ComEd customers save energy and money.
HLR technology allows for downsizing of HVAC systems by eliminating the parasitic load associated with the practice of “air replacement”. Downsizing of HVAC systems delivers immediate capital-cost savings on new HVAC systems and up to 40 percent ongoing energy savings. Furthermore, recycling indoor air also means reducing the building’s intake of polluted outside air.
“We are proud to kick off the adoption of HLR solutions in Chicago”, says John Orabutt, chief engineer at 155 North Wacker. “The repeated success of HLR systems in New York, Boston, Miami and elsewhere convinced the building owners to deploy it here at 155 North Wacker, and we look forward to reaping the benefits of energy savings and indoor air quality.”
