Cool roofs save energy and are particularly suited for low rise buildings in hot climates. This paper presents results of potential energy savings for existing houses in two islands (Sicily and Jamaica) based on validated thermal models. It also presents the lifecycle environmental impact of the cool paint focussing on both the midpoint and endpoint impact categories and compares these with thermal insulation impact. It was found that significant net energy benefits are possible in both locations by a cool roof, more pronounced in Jamaica, which has no heating demand; savings are comparable with thermal insulation reductions. The environmental impact of cool paint is lower than a variety of thermal insulation materials with the exception of water depletion potential. The main hotspots of the cool paint are the production of the polymer followed by the production of the pigment.

凉爽的屋顶涂料对环境的影响:两个热岛上房屋改建的案例研究

凉爽的屋顶可以节省能源,特别适合在炎热气候下的低层建筑。本文基于经过验证的热模型,介绍了两个岛屿(西西里岛和牙买加)现有房屋的潜在节能效果。它还以中点和端点影响类别为重点,介绍了冷涂料对生命周期的环境影响,并将这些影响与隔热影响进行了比较。人们发现,凉爽的屋顶在两个地方都可能带来显着的净能源收益,而牙买加在没有供暖需求的情况下更为明显。节省的费用可与绝热减少相媲美。除了可能的耗水量外,凉爽涂料对环境的影响要比各种隔热材料低。
