The primary goal of this research was to minimise the energy consumed by heating and cooling loads in residential buildings in a sub-humid Mediterranean climate zone. This was achieved by optimising the design variables of various building envelopes using DesignBuilder software to compare the thermal performance of a baseline building model located in Ajlun (city in northern Jordan mountainous area) with the performance of other buildings with various design configurations. A sensitivity analysis (SA) was then conducted for twelve design variables to evaluate their influence on both cooling and heating loads using a regression method. The variables were divided into two groups according to their importance: a high importance design variables (window to wall ratio, local shading type, round floor construction, natural ventilation rate, infiltration rate (ac/h), glazing type, flat roof construction) and a low importance design variables (partition construction, site orientation, external wall construction, window blind type, window shading control schedule).The final results show significant reduction in the total energy consumption.

这项研究的主要目标是使半湿润的地中海气候区住宅建筑中的供暖和制冷负荷所消耗的能量最小化。这是通过使用DesignBuilder软件优化各种建筑围护结构的设计变量，以比较位于Ajlun（约旦北部山区的城市）的基准建筑模型的热性能与具有各种设计配置的其他建筑的性能来实现的。然后对12个设计变量进行了敏感性分析（SA），以使用回归方法评估它们对冷负荷和热负荷的影响。根据变量的重要性将其分为两组：高度重要的设计变量（窗与墙的比例，局部阴影类型，圆形地板的结构，自然通风率，
