Abstract

Abstract The building sector has a high level of energy consumption caused mainly by the buildings heating and cooling energy demands to satisfy indoor comfort requirements. Reducing both the amount of energy consumed and the life cycle cost is a main challenge for the construction of buildings. It is evident that sustainable materials have low environmental impacts and need low consumption of energetic resources in addition to their durability and recyclability. Therefore, this research aims to test different sustainable materials available in Egypt for the construction of building envelopes that include local stones “Marble and Limestone” and insulation materials “Polyurethane- expanded and Extruded polystyrene (XPS) foam” in order to achieve savings in energy and total life cycle cost. The simulation tests were conducted through Design Builder software. The results aim to provide solutions for building designers to achieve energy-efficiency and costeffective design. The proposed alternatives showed a significant reduction in energy consumption by up to 62% and the total life cycle costs significantly reduced by up to 45.8%.

建筑围护结构的能源性能分析

摘要建筑行业的能源消耗水平较高，主要是由于建筑对供暖和制冷能源的需求，以满足室内舒适性要求。降低能源消耗量和生命周期成本是建筑施工面临的主要挑战。很明显，可持续材料对环境的影响很低，除了耐久性和可回收性外，还需要低能耗的能源。因此，本研究旨在测试埃及可用于建筑围护结构的不同可持续材料，包括当地石材“大理石和石灰石”和绝缘材料“聚氨酯-膨胀和挤出聚苯乙烯（XPS）泡沫”，以实现能源节约和总生命周期成本。模拟测试是通过Design Builder软件进行的。研究结果旨在为建筑设计师提供实现能源效率和成本效益设计的解决方案。所提出的替代方案显示，能源消耗显著降低了62%，总生命周期成本显著降低了45.8%。
