Roofs are important assets in the struggle to reduce the carbon footprint of buildings. Cool roof technology offers one way in which this can be tackled. The concept is being tested via the establishment of some sheds with cool roofs at the Burnley campus of Melbourne University. TRNSYS is being utilised in order to predict the thermal response of the test huts and those results are being compared against measured temperatures. A marked temperature decrease has been noted in the summer temperatures of the sheds with cool roof coatings
