One South Wacker is a Class A office building in Chicago, IL, offering approximately 1,300,000 square feet of rentable space. Built in 1982, One South Wacker houses tenants including accountants, attorneys, trading firms, insurance companies, and consultants, and the building is over 80 percent occupied.

An emphasis on energy management and sustainability is standard practice at One South Wacker. The on-site Jones Lang LaSalle management team continually applies no- and low-cost energy efficiency measures including implementing an enhanced preventative maintenance program, completing lighting audits, optimizing HVAC start/stop times, load shedding, engaging janitorial and security staff to turn off unneeded lights, and minimizing heating and cooling in vacant space.

As part of ongoing energy management efforts, several upgrades have been completed. The domestic hot water system was replaced and variable frequency drives (VFDs) installed. Defective sensors on the automation system have been replaced. Retrofits were made to base building lighting to add electronic ballasts and motion sensors, and restroom equipment was replaced with low-flow models. 

Building owner TIAA-CREF, an ENERGY STAR Partner of the Year award winner in multiple years, has a strong commitment to energy management and has set portfolio-wide goals for energy-efficient buildings.

Property management communicates with tenants about energy efficiency and sustainability, providing energy-saving tips to help the building maintain its superior performance. The building participated in The Chicago Green Office Challenge and the Change the World, Start with ENERGY STAR campaign, providing free CFLs for tenants to take home, in addition to handouts about energy-efficient lighting.
