Van Wormer Hall and Teachers College/Dyer Hall are both existing buildings of historic importance on the University of Cincinnati campus. A major objective of the LEED rating process promoting sustainable and high-performance design is the efficient reuse of existing building stock. In the complete rehabilitation of these campus buildings additional usable space has been developed, mechanical system efficiency improved through commissioning (fine tuning) equipment which is reduced in size due to improvements in the building envelope: insulation, glazing, roofing, daylight control (to reduce lighting load and other mechanical load requirements). Occupant comfort and performance are improved due to improvements in indoor environmental quality through air filtration, more individual controllability of systems and reduction in voc emitting materials. Resource consumption is reduced through reuse of buildings with minimal increase in footprint, reduction in construction and demolition waste, increase in recycled content of materials and use of locally harvested and manufactured materials.
