The aim of this project is to provide a better quantitative understanding of how large cool roofs behave during cool or cold weather conditions, as a function of location around Australia.
This project is designed to maximise the utilisation of the previous work carried out under CRC LCL project RP1037 ‘Driving Increased Utilisation of Cool Roofs on Large-Footprint Buildings’.
The key technical output from the project will be a new model that better predicts the impacts of higher heating requirements in cold weather that are a result of higher rates of night-time radiative heat losses and lower day-time solar gains, for cool roof surfaces as compared to various non- cool roofing alternatives. This new model will expand the Utilisation Potential of the experimental and numerical work of RP1037 by filling a crucial gap in knowledge. It will enhance the accuracy and confidence of energy modelling predictions of building performance, and through it, the cost : benefit analysis of cool roof materials for large roofs in all major Australian climate zones
