Center for Neighborhood Technology
by Jean Carroon
The Center for Neighborhood Technology in Chicago, Illinois, moved into a former textile factory in 1987 and began its second renovation in 2000 to accommodate greater space needs. Designed by architect Jonathan Boyer (now a principal at Farr Associates), the new office space offers an exemplary model of sustainable adaptive reuse that takes advantage of environmentally responsible products and technologies not available in the 1980s.

The original decision to relocate to Chicago's northeastern side was to enhance public transportation options for employees and visitors. The Center's web site notes that people can easily come and go, do errands, or eat lunch by walking or using public transportation. The commitment to urban sustainability and environmental education has attracted hundreds of visitors, and tours are held almost daily to enlighten the community on ecological design.
Site and Water
A light-colored roof was installed to reduce the absorption of the sun's heat and reduce the interior air temperature during warm months. The adjacent lot is planted as a sliver park using native, drought-tolerant vegetation to provide a cool oasis for the neighborhood and trees that shade the building to further lower the air-conditioning requirements. Rainwater percolates through the garden and pervious parking lot to replenish aquifers. Low-flow fixtures inside the building have reduced potable water consumption by 30 percent.
