Thomas Hall on the Eastern Illinois University campus in Charleston, Illinois is a co-educational dormitory and dining facility comprised of two residential wings, each with four floors for residential communities, a main level with offices, community lounge, and lower level with laundry and mechanical spaces. Food service is accessed in the dining facility that is located between Andrews and Thomas Halls and was included in the energy audit for this building. Similar to the adjacent Andrews Hall, the original building was constructed in the 1960s before the advent of modern energy codes, and the exterior wall construction was found to be very inefficient. In this case, the addition of a new exterior insulation system was found to be quite cost-effective. This building has significant overheating and comfort issues due to the poor insulation and perimeter heating system control issues, and a detailed analysis was prepared to demonstrate the benefits of suggested revisions.
