January 8, 2015 By Linda Hardesty

With the help of EDF Climate Corps, the facilities team at 77 West Wacker in Chicago cut its energy costs by almost 50 percent.

As a Class A building, 77 West Wacker has 50 floors, 16 tenants and 959,258 square feet of rentable space. With its all-electric infrastructure, JLL business and operational leaders partnered to identify where energy savings could be generated. By driving transparency into the data, customizing the building’s automation system, and engaging tenants on energy use, JLL reduced its annual energy use by 2 million kWh and decreased its electrical expenses by 47 percent.
