In recent years, several studies on residential energy consumption and new strategies for its reduction have been carried out. The literature reports that thermal inertia can have an influence on energy demand and, to a greater extent, on the thermal comfort of the buildings. The performance of thermal inertia in buildings located in different regions or countries has been analysed, comparing structures or materials having high and low thermal inertia through energy simulations or empirical studies. However, the optimal thermal inertia of a building according to different climates has not been established. In this study, optimum values were determined for the different properties that define thermal inertia (thermal conductivity, specific heat capacity, and density) that would allow to maintain the indoor annual operative temperature within the thermal comfort range (18–24°C) of a standard dwelling. Energy simulations were carried out in DesignBuilder using climate data from 10 cities in different Chilean climate zones. The results show the minimum thermal conductivity as optimal regardless of climate (0.025 and 0.03 W/(m∙K)), while the optimal density ranges fluctuate between 1800 and 2500 kg/m³ varying according to the climate zone. Finally, it was determined that specific heat capacity was not influential in the thermal comfort of the analysed dwelling.

近年来，已经进行了一些关于住宅能耗的研究以及减少能耗的新策略。文献报道，热惯性会影响能量需求，并在更大程度上影响建筑物的热舒适性。分析了位于不同地区或国家/地区的建筑物中的热惯性性能，并通过能量模拟或经验研究比较了具有高和低热惯性的结构或材料。然而，尚未建立根据不同气候的建筑物的最佳热惯性。在这项研究中，确定了定义热惯性（导热系数，比热容，和密度），可以将室内年度工作温度保持在标准住宅的热舒适范围（18–24°C）之内。使用来自智利不同气候区的10个城市的气候数据，在DesignBuilder中进行了能源模拟。结果表明，不管气候如何，最小导热系数都是最佳的（0.025和0.03 W /（m∙K）），而最佳密度范围在1800和2500 kg / m之间波动³根据气候带而异。最后，确定比热容量对所分析住宅的热舒适性没有影响。
