Lake Forest, IL 60045
Map It!


Located in Lake County, IL, Grainger's corporate headquarters comprise approximately 650,000 square feet of office space on 125 acres. This area includes the grounds directly surrounding the building and a vast area of woods, ponds, and prairie. In addition, the Company maintains an adjacent 110-acre parcel of property in an agricultural state.

The building is fully automated utilizing Siemens' building automation system (BAS) for control of HVAC and lighting with over 30,000 controllable and operating points. The chilled water system is composed of four 800-ton Mycom rotary screw chillers that make 25,000 tons of ice in a 250,000 gallon ice storage tank. The chillers operate at night during off-peak power periods, and the ice water is pumped through heat exchangers to cool the building. The original two 300-horsepower fire tube boilers remain in place and are now used only for secondary back-up heat.  Recently three MFD boilers were installed, which modulate to control the hydronic water temperature.  Five fan systems control the comfort of the occupants and are monitored via the BAS and controlled by Square D variable frequency drives (VFDs). All fans and pumps are on VFDs for optimal energy usage. The facility management team constantly monitors the energy usage via the BAS and utility Web sites to minimize consumption.

The site contains two man-made ponds that gather all rain water from the parking lots and roofs and is the sole source of irrigation water for the property. Every effort has been made from the inception of the property design to maintain the natural environment of plant and animal life.

Site sustainability efforts include the utilization of compostable cups, flatware, and food carriers, in addition to future onsite composting of kitchen waste. The site has achieved the ENERGY STAR for superior energy performance and earned sufficient points under the U.S. Green Building Council's Leadership in Energy and Environmental Design (LEED) Existing Buildings Rating System to certify as Gold.
