Cool Roof Calculator – Direct solar radiations on the roof is responsible for increasing summer cooling load and reducing winters heating load. Application of reflective coating and membranes can help in reducing cooling loads but increasing heating requirement. Cool Roof Calculator is used to estimate the net energy saved with the application of cool roof concepts in the building.
