IMEG provided engineering services for the renovation of Marston Hall, home of the College of Engineering and a landmark on the Iowa State University campus.  

Constructed in 1903, the facility no longer provided an appropriate environment for teaching, student services, faculty and staff. Part of the University’s strategic plan, the renovation was designed to help attract the best faculty members and students, and help the college remain competitive. 

Work included remodeling the entire interior (except for the main east entrance), including the auditorium and classrooms, student and career services space, public and administrative spaces, and restrooms. Other spaces include open offices, conference rooms, a lobby, and student interaction spaces. Infrastructure upgrades included the heating, ventilation and air conditioning systems, electrical and telecommunications, and new exit stairs and elevators. 

IMEG provided an energy modeling analysis to help inform design decisions to optimize HVAC and lighting design. Sustainable design features include chilled beam cooling, radiant heating, dedicated outside air ventilation with heat recovery and passive dehumidification, daylight harvesting, LED lighting, occupancy sensors, low-flow plumbing fixtures, and underfloor air distribution. The project is LEED Gold certified. 

Design challenges included acoustical control, and site utility planning and relocation. The project received a LEED innovation credit for complying with acoustic criteria set forth in LEED for Schools, even though it was certified under LEED NC.
