President Preckwinkle Announces LEED Gold Certification for Cook County’s Dunne Administration Building
Cook County Board President Toni Preckwinkle today announced the County’s Dunne Administrative Building has achieved LEED Gold certification.
LEED stands for Leadership in Energy and Environmental Design, and denotes an improvement to a building’s lifecycle performance, based on a point system, that provides associated environmental, health and financial benefits.
LEED Gold is the second highest level of achievement. Cook County has an ordinance that all new construction in the County must be LEED certified by the U.S. Green Building Council (USGBC).
"When I first took office, I said I wanted to make Cook County a world-class model of sustainability, with our County buildings and assets a major focus," Preckwinkle said. "Some of our other County buildings such as Provident Hospital and Domestic Violence Courthouse have received LEED Silver certification. The LEED Gold certification of our main administrative building is an important milestone and meaningful way to celebrate Earth Day."
Among the goals achieved for the Cook County Dunne Building at 69 W. Washington are:
- An ENERGYSTAR score of 91, which means 69 W. Washington is in the top 9th percentile of energy efficient buildings.
- Installing efficient restrooms, which not only decreases operating costs but also reduces water use, thus protecting the natural water cycle and saving resources.
- Instituting a low-impact hardscape and landscape maintenance program for cleaning and maintaining the exterior of the building. This includes composting landscape waste, reducing gas-powered maintenance machinery and using environmentally friendly ice melting and cleaning products.
- Implementing an integrated pest management plan which focuses on increased monitoring and reduction of toxic pesticides.
- The building benefits from pedestrian access to public transportation and from proximity to community services. This reduces the building community’s impact on the environment, as transportation accounts for 31 percent of carbon emissions in the United States.
Indoor Environmental Quality:
- Implementation of a healthy High Performing Green Cleaning Program to reduce the exposure of building occupants and maintenance personnel to potentially hazardous chemical biological and particulate contaminants.
- High-quality air filtration that reduces the amount of particulates -- such as lint, dirt, dust and bacteria -- that is introduced into the building.
