An Improvement on Heat Reduction in a Lightweight Composite Roof Material

Abstract

Abstract The objective of this research is to improve heat reduction in a lightweight composite roof material. This research has studied and compared roofing material with opening for ventilation and without opening. A comprehensive model is simulated from computational fluid dynamics simulation of a finite element software. The simulation considered three aspects of heat transfer which are heat conduction, heat convection and radiation. The simulation result showed that the roofing material with opening for ventilation can reduce temperature in the composite roof about 20%
