This 26,000-square-foot science addition and 13,000-square-foot renovation at Glenbard West High School produced a centrally located science department, a vastly upgraded mechanical system and enhanced ADA access. The science department contains eight new, state-of-the art labs – four chemistry, four physics – and an office for science teachers, promoting collaboration among faculty and student peers. The six former science labs were converted into eight classrooms for business and world language. Atop the new addition is a green roof with maintenance-free native vegetation, which reduces rainwater runoff and helps keep the school cooler during warm weather. The green roof also serves as a teaching space, as classes can utilize the vegetation to support lessons and access the solar panels to learn about renewable energy.
