Retrofit to Remember

Partners including JLL, ComEd, Zeller Realty and Cypress Envirosystems gathered in Chicago in late February to show off what they called “The Smartest Energy Efficiency Retrofit in Chicago” at 311 South Wacker, a 65-story building originally completed in 1990.

Bob Best of JLL described Zeller’s goal of making the 1.4-million-sq.-ft. tower a model. First step: Replaced the thermostats with 944 wireless pneumatic thermostats through Cypress. Then apply JLL’s IntelliCommand smart building system, now operating in more than 120 buildings around the world. Next, stir in the largest energy incentive check for a commercial building in history: $402,318.50, presented by ComEd in 2015.
