COOL METAL ROOFING: BUILDING CODES AND STANDARDS
Cooling energy reduction of up to 25% or more has been attributed to cool metal roofing materials. Municipalities are embracing them to mitigate the urban heat island effect that can make daytime temperatures within the city higher than normal and prevents heat dissipation at night. Cool metal roofs can decrease the demand on the energy grid during the summer by lowering peak demand. A cool metal roof is a crucial part of an energy efficient structure, one that receives the majority of the sun’s rays and has the maximum impact on solar heating. Since energy-efficient construction is now in the mainstream, codes and standards are being developed to ensure quality and to encourage further adoption. WHO IS DEVELOPING THE CODES AND STANDARDS? EPA: Energy Star The Environmental Protection Agency (EPA) released the voluntary Energy Star program in 1992 and it continues today, providing information on saving energy and conferring Energy Star certification and recognition to home and bu...
