A Performance Analysis of Cool Roof products comparing monitored data with modelled data to facilitate performance predictions

Abstract

Dulux Group (Australia) P/L has applied cool roof coatings to three buildings of a retail / trade nature and monitored the energy use to determine the benefits of the cool roof coating. Energy savings have been demonstrated although as yet there is limited ability to predict the benefits of the product for other buildings. This is due to the complex interaction of variable such as climate, occupancy building form and material properties, and HVAC systems. The purpose of this study is to link the existing performance results to the ability to predict accurate energy savings of this product through energy modeling.
