Cool Roofs – Saving Hoteliers Energy Costs!

• In the summer, we wear lighter colored clothing to reflect heat rather than absorb it to stay cooler. A cool roof works in the same fashion.
• Cool roofs are made of materials with High Solar Reflectance which is measured by the Solar Reflectance Index (SRI). The USGBC defines SRI as a measure of the constructed surface’s ability to stay cool in the sun by reflecting solar radiation and emitting thermal radiation. A standard black has an initial SRI of 0, and a standard white surface has an initial SRI of 100. These types of material are made of highly reflective paint, sheet coverings, membranes, or highly reflective tiles or shingles.
• Costs for cool roofs vary greatly based on roofing type and project geography. In general, developers should expect to pay a slight premium over a conventional roof.

Benefits:

• Reduce Roof Heat – Standard dark roofs can reach temperatures of 150°F or more in the summer sun. Cool roofs absorb less heat and stay up to 50–60°F cooler than conventional materials during peak summer weather.

• Reduce Energy Costs – A cool roof transfers less heat to the building below. This has been shown in studies to save building owners up to 10%-15% in energy costs during these time periods.
• Environmentally Friendly – Temperatures are often 2-5 degrees higher in cities than in their surrounding areas, because buildings emit more heat which stays in the atmosphere longer. This temperature discrepancy is the result of a phenomenon known as the urban heat island effect. Raised temperatures from urban heat islands, can affect a community’s environment and quality of life. This is why cool roof technology especially benefits buildings found in urban areas where heat island effect is an issue.
