Executive Summary: Comparative Evaluation Of The Impact Of Roofing Systems On Residential Cooling Energy Demand In Florida, Florida Solar Energy Center, John Sherwin

FSEC Energy Research Center®

Roof and attic thermal performance exert a powerful influence on cooling energy use in Florida homes. Unshaded residential roofs are heated by solar radiation causing high afternoon attic air temperatures. The large influence on cooling is due to increased ceiling heat transfer as well as heat gains to the duct systems which are typically located in the attic space (Figure E-1). The Florida Power and Light Company and the Florida Solar Energy Center instrumented six side-by-side Habitat homes in Ft. Myers, Florida with identical floor plans and orientation, R-19 ceiling insulation, but with different roofing systems designed to reduce attic …

Energy Efficient Design For Florida Educational Facilities, Florida Solar Energy Center, Janet Mcilvaine

FSEC Energy Research Center®

This manual addresses energy efficiency options for new educational facilities in Florida. The recommendations may not be valid when considered outside Florida's hot humid climate or for purposes other than new construction.

Construction funds spent on new construction heavily outweigh (67%) those spent on retrofit, as reported in an annual statistical analysis published by American School and University (September 1992). The comprehensive survey showed that construction funds for new educational facilities nationwide have risen for eight consecutive years, and no region has experienced more growth than the Southeast. Currently, funds spent on energy services (excluding capital outlay, salaries, benefits, and …
