The building envelope is the boundary between the outer and inner spaces and it is considered as the most significant part in the process of preservation of internal spaces cooling energy consumption. In this context, it is argued that the weakest point in the envelope with the highest transmittance of thermal energy into and out of the internal spaces is the openings (windows and doors) which are affected by many factors such as their ratio, material thermal properties and construction. Therefore, this study sheds light on the alternatives of the envelope design generated with the help of a computer-based simulation tool, Design-Builder, as it has great possibilities for creating simulated scenarios for a specific building or space by linking these scenarios with specific changes in the building parameters. Thus, the study will focus on creating different scenarios for a selected classroom in the College of Arts and Design at Princess Nourah bint Abdulrahman University (Riyadh, KSA), with the aim of associating the openings ratios (20%, 30%, 50%, 100%) with wall thickness (12 cm, 25 cm solid brick, 25 cm hollow brick) and energy consumption. Optimum alternatives for the opening ratio and construction materials with the lowest cooling loads during working hours are proposed.

开口率和壁厚对教育建筑能源性能的影响

建筑围护结构是外部空间和内部空间之间的边界，被认为是保存内部空间冷却能耗的最重要部分。在这种情况下，有争议的是，进入和流出内部空间的热能传递率最高的封套中最薄弱的地方是开口（门窗），该开口受到许多因素的影响，例如它们的比率，材料热性能和建设。因此，本研究揭示了借助基于计算机的仿真工具Design-Builder生成的信封设计的替代方案，因为它有很大的可能性通过将这些方案与特定的建筑联系起来，为特定的建筑物或空间创建模拟的方案。建筑参数的变化。从而，这项研究将着重于为努拉·本·阿卜杜拉赫曼公主大学（利雅得，KSA）艺术与设计学院选定的教室创建不同的场景，目的是将开口率（20％，30％，50％，100） ％）的壁厚（12厘米，25厘米实心砖，25厘米空心砖）和能耗。对于在工作时间内具有最低冷却负荷的开口率和建筑材料，提出了最佳替代方案。
