Designed by Chicago-based Farr Associates Architecture and Urban Design, the building uses solar and geothermal energy, a rooftop garden, and a natural habitat to filter storm water. The city invested $9 million in clean-up costs and another $5.4 million toward construction and renovation. The 1952 building is surrounded by a 17-acre site that was formerly the Sacramento Crushing Corporation, a construction materials recycler. The company was closed in 1996 after 600,000 cubic yards of waste were discovered on the site. The money for the Chicago Center for Green Technology came from a settlement with the Commonwealth Edison Company. **This building was originally imported from the U.S. Department of Energy Energy Efficiency and Renewable Energy Building Technologies Database (http://eere.buildinggreen.com/overview.cfm?projectid=97) on 2009-06-06.
