With regard to hotter summer months weather conditions, eco-friendly roofing can reduce the photo voltaic heating of a creating by reflecting 27% of solar radiation, absorbing 60% from the vegetation as a result of photosynthesis and evapotranspiration, and absorbing the remaining 13% in review the increasing medium.
