While there have been studies done to show how effective cool metal roofing is particularly by the oak ridge national laboratory this would be a real life real time study to prove the benefits of cool metal roofing. Case studies shown are specific to client projects comparing before and after results through cooling intensive periods. Green roof temperatures can be 30 40 f lower than those of conventional roofs and can reduce city wide ambient temperatures by up to 5 f.
For the examined case study it was found that a roof reflecticity of 0 6 0 7 is the. A cool roof is a roofing system that delivers higher solar reflectance the ability to reflect the visible infrared and ultraviolet wavelengths of the sun reducing heat transfer to the building and higher thermal emittance the ability to radiate absorbed or non reflected solar energy than standard designed roofing products. 1 2 in addition green roofs can reduce building energy use by 0 7 compared to conventional roofs reducing peak electricity demand and leading to an annual savings of 0 23 per square foot of the roof.
