Thermal insulation is a significant factor in building construction. As a result, Green Star in Australia requires building envelopes to be properly insulated. Further, green buildings require at least 15% above the required R-values (m2K/W) for achieving Green Star credit points. Thermal insulation of the roof depends on various factors such as insulation material, sarking material, air films and roof covering. Therefore, there are many options with different combinations available to obtain the required total R-values. This research aims to identify optimum solutions for roofing solutions considering the required R-Values and the life-cycle cost. There are ten commonly used roof types in Australia. For each of these roofs, there are many variants available with different material. Therefore, this research calculated the life-cycle cost for more than 2000 options in roofing solutions, and analyse the options to identify the optimum solutions for each climatic zone in Australia. Life-cycle cost adopts net...

生命周期成本视角的绿色建筑屋顶解决方案的最佳选择

隔热是建筑施工中的重要因素。因此，澳大利亚的绿色之星要求建筑物的围护结构要适当绝缘。此外，绿色建筑需要至少比要求的R值（m2K / W）高出15％才能获得Green Star信用点。屋顶的隔热取决于各种因素，例如隔热材料，防潮材料，气膜和屋顶覆盖物。因此，有许多具有不同组合的选项可用于获得所需的总R值。这项研究旨在为屋顶解决方案确定最佳解决方案，同时考虑所需的R值和生命周期成本。澳大利亚有十种常用的屋顶类型。对于这些屋顶中的每一个，都有许多可用不同材料制成的变体。因此，这项研究计算了2000多种屋面解决方案的生命周期成本，并分析了这些方案以找出适用于澳大利亚每个气候区的最佳解决方案。生命周期成本采用净额
