Abstract

The Florida Department of Community Affairs (DCA) is seeking to examine the impact and necessity of residential attic ventilation in Florida homes. Here, we provide technical support by examining existing data sources on the impacts of attic ventilation both on cooling and heatingenergy use as well as to attic and home moisture levels. In particular we evaluate the issues with sealed attic construction where the attic is unvented and expanded foam insulation is applied directly to the underside of the roof decking. We also report the data from Florida Solar Energy Center (FSEC) instrumented facilities to add unique information to the evaluation. This review emphasizes literature where there was extensive monitoring in Florida and other hot climates. Analysis of the empirical data suggest inferences on attic thermal performance and associated impacts on space cooling and space heating as well as attic moisture levels. Others potential influences are also discussed.
