THE RENOVATION AND REHABILITATION OF HISTORIC BUILDING ENVELOPES: AN IN-DEPTH BUILDING PERFORMANCE AND THERMAL COMFORT ANALYSIS
Historic building preservation should not be considered an obstacle to sustainability, they inherently share the fundamental goal of preserving the environment. The renovation and rehabilitation of a building envelope provides a preservation benefit of the embodied value/energy of the historic building. The scope of this paper examines how the architectural preservation of Ludwig Mies van Der Rohe's S.R. Crown Hall, (home to the Illinois Institute of Technology's College of Architecture) has impacted the energy use intensity (EUI) of the building as well as the indoor environmental quality (thermal comfort) of its occupants. S.R. Crown Hall has adapted to many new technologies and ventilation strategies in a recent envelope rehabilitation but at the most fundamental level of the project the original philosophy of Mies' 1954 design of the building had to be maintained (the fabric of the building was regarded as sacrosanct). Advanced building simulation was used to provide an in4depth building performance analysis to derive the EUI of the building and to model the occupant thermal comfort with the use of Computational Fluid Dynamics (CFD) to simulate internal airflows.
