An existing four-story classroom building with limited ceiling space was up-fitted with two outdoor air energy recovery units. The units were added in the existing attic space, and the new equipment needed to be utilized in the future renovation project. Fabric ductwork was installed to supply the ventilation to each of the classrooms. Using this type of ductwork was a cost-effective solution which allowed for minimal disruption in the occupied areas. The building prior to this project had seen an average summer relative humidity of 75-85 percent. Upon completion in the summer of 2007, average summer relative humidity was 50-60 percent. The energy recovery wheels installed saved 50 percent of the required 100 tons of cooling needed to condition the ventilation air.
