Thermal analysis of roof‐spray cooling

open access: yesInternational Journal of Energy Research, 1998
Roof-spray cooling systems have been developed and implemented to reduce the heat gain through roofs so that conventional cooling systems can be reduced in size or eliminated. Currently, roof-spray systems are achieving greater effectiveness due to the availability of direct digital controls (DDC).

Cool Roof Technology

open access: yes, 2017
The motive of undertaking this project “cool roofs technology” discusses the various technical and design considerations as applicable for a composite climate. The primary intent of “cool roof technology” is to reduce the amount of energy (heat) absorbed by a roof surface and maintain the temperature of upper floors in building in summer season.
