The economic optimum insulation thicknesses (OIT) for heated buildings in five different climate regions in Turkiye were determined, and the energy, cost, and life cycle-based environmental performances were analyzed. Calculations were performed using three different fuels (natural gas, fuel oil, and coal) and four different insulation materials: expanded polystyrene (EPS), rock wool (RW), glass wool (GW), and extruded polystyrene (XPS). This study utilized a thermoeconomic approach to evaluate energy and economic performance and a life cycle assessment (LCA) approach to assess environmental impacts, ensuring a comprehensive analysis of insulation strategies. The impacts of climate change factors were expressed as kg CO2 equivalent (kgCO2eq) using 100-years global warming potential (GWP). The annual energy savings varying from 18.41 to 258.15 kWh/(year.m2) for the warmer and the colder climate zones, respectively. The maximum avoided environmental impact (AEI) due to energy saved from thermal insulation was 144.11 kgCO2eq/(year.m2) for coal and RW in coldest climate zone, while the minimum AEI was 5.31 kgCO2eq/(year.m2) for natural gas and XPS in warmest climate zone. Among insulation materials, EPS offers the shortest environmental payback period, whereas RW requires the longest, highlighting material-specific trade-offs. In all climate zones, environmental payback periods are much shorter than economic ones.

通过热经济性和生命周期评估分析对建筑外墙保温厚度进行环境经济优化


确定了土耳其 5 个不同气候区供暖建筑的经济最佳保温厚度 （OIT），并分析了基于能源、成本和生命周期的环境性能。使用三种不同的燃料（天然气、燃料油和煤）和四种不同的绝缘材料进行计算：发泡聚苯乙烯 （EPS）、岩棉 （RW）、玻璃棉 （GW） 和挤塑聚苯乙烯 （XPS）。本研究采用热经济学方法来评估能源和经济绩效，并采用生命周期评估 （LCA） 方法来评估环境影响，确保对绝缘策略进行全面分析。气候变化因素的影响使用 100 年全球变暖潜能值 （GWP） 表示为千克二氧化碳当量 （kgCO2eq）。温暖和寒冷气候区的年节能量分别为 18.41 至 258.15 kWh/（year.m2） 不等。在最冷气候区，煤炭和 RW 因隔热节省的能源而避免的最大环境影响 （AEI） 为 144.11 kgCO2eq/（year.m2），而天然气和 XPS 的最小 AEI 为 5.31 kgCO2eq/（year.m2） 在最温暖气候区。在绝缘材料中，EPS 的环境回收期最短，而 RW 需要最长，突出了特定于材料的权衡。在所有气候区，环境投资回收期都比经济投资回收期短得多。
