Cool roofs are building coverings having high reflectance to solar radiation and high emittance in the infrared range. They can provide an effective solution to building overheating during hot seasons.In the U.S.A. the cool roofs have been investigated extensively. Certification procedures have also been developed by independent bodies, and certified roof products are commercially available.In the aim of verifying the potential of cool roof technologies for the Italian climate, an investigation was started at the Dept. of Mechanical and Civil Engineering at Modena.Early results are presented for an experimental cool roof. The work is completed with an analysis of the thermal behavior of a typical low-slope roof and a brief review of existing certification programs and commercially available products.
