College of Lake County

Science and Engineering Building

A green future in higher education.

The College of Lake County's new science and engineering building supports chemistry, microbiology, biology, anatomy-physiology, engineering (laser, photonics, and renewable energy) programs, and includes teaching labs, classrooms, offices, and support space. AEI energy modeling helped determine the most effective means of achieve substantial energy savings. With a projected Energy Use Intensity of 88 kbtu/sf, the building is expected to use 66% less energy than the ASHRAE 90.1-2007 baseline for an energy cost savings of 52%.

Located in the far northeastern suburbs of Chicago, the College of Lake County is a two-year community college that offers a wide range of academic program choices to over 18,000 students.

The project is anticipated to achieve LEED Platinum certification. Sustainability features included in AEI’s design are: variable volume building and fume hood exhaust system with energy recovery; 56 kW rooftop solar panel array; optimized envelope shading and daylight harvesting; and, rainwater harvesting.

Expanding the College's sustainability goals, an AEI-designed campus-wide geothermal heating & cooling system will provide heating and cooling to all campus buildings. The initial phase includes primary infrastructure and eighty 500-foot deep boreholes, expandable to total 700 wells with an estimated 2,275 tons of heating and cooling capacity.
