Prior to the 49,800 SF renovation Keim Hall experienced uneven heating and cooling issues, which made some laboratories unable to sustain the equipment that scientists needed to conduct research and teach students. The interior of the building was completely reconfigured with new laboratories, classrooms, meeting rooms, and office space. Usable space was added to the building by moving the center corridor that originally ran through the building's wings to an outer wall, along with moving the heating and cooling equipment to a penthouse in the top level The building received a new exterior facade on the south wall of the interior courtyard. The north wall of the building was opened up and a new walkway and three-story curtain wall was installed to give panoramic views of the courtyard.
