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.
Cool roof technology case study.
Description of the building and cool roof technology.
Are white roofs cooler and more energy efficient than non white roofs.
The case of temperate climates the type operation and thermal characteristics of the building should be considered carefully to determine potential benefits of the application of cool roof technology.
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.
