Chicago City Hall Green Roof

In 1999, CDF led the design process to convert the Chicago City Hall rooftop into a green roof pilot project. As a component of the Chicago Department of Environment's Urban Heat Island Initiative, the Chicago City Hall green roof was one of three national pilot projects sponsored by the U.S. EPA to study the efficacy of green roof technologies. CDF's scope for this unique project included design of the green roof system as well as grading and drainage design, and plant selection. The green roof research demonstration project tests over 100 species of native, cultivated and non-native plants, and utilizes water harvesting and recycling for irrigation.
