Cool Roof Retrofits as an Alternative to Green Roofs
Cool roof paint is a practical, low‐cost retrofit option to improve the thermal performance of buildings where there are significant cooling loads. This chapter looks at their viability in a cool‐temperate climate and presents the results of four experiments investigating a CRP roof retrofit of a metal roof; the extension of this data through modelling to test the sensitivity of CRP to changes in shading, roof pitch, insulation levels, insulation location and building‐roof‐to‐surface‐area ratios; the testing of the CRP against a green roof retrofit; and finally the benefit of white roofs on electricity production through photovoltaics. The outcomes show that there is a benefit to CRPs used in a residential property in Melbourne, reducing the cooling loads. The research shows that CRP is most beneficial for the retrofit of short industrial buildings. Other retrofit scenarios and benefits are discussed. Overall, CRP treatments have a role in adding to the retrofit options when a green roof may not be appropriate.
