在学校建筑，特别是学习空间，良好的日光和热条件对促进教育进程非常重要，因为不令人满意的舒适度可能会降低教师和学生的体能和智力表现。然而，实现成功的课堂设计是相当复杂的，因为它需要平衡各种相互关联的因素，这对炎热和干燥的气候特别具有挑战性。近年来，建筑优化方法有了很大的改进，用于寻找高性能设计方案的遗传算法在解决这类复杂问题方面表现出了很高的效率。这项研究展示了在炎热干燥的气候下，如何将这种方法应用于优化中学教室的热、光和能源性能。通过针对蝗虫的Octopus插件，使用参数方法和渐进式多目标计算，将各种窗墙比、墙体材料、玻璃类型和遮阳设备组合在一起，得出潜在的解决方案，在提供日光和热舒适性之间实现良好平衡，同时确保低能耗。结果表明，通过对围护结构参数的修改，可以提高建筑的日光照度、自适应热舒适性和节能效果。探索了不同建筑朝向的解决方案，为炎热干燥气候下学校建筑的窗墙比提供了建议。结果表明，如何在建筑设计过程的早期阶段使用优化方法，以了解如何定制建筑围护结构，以确保良好的建筑性能，包括舒适性和能源性能。
In school buildings, especially learning spaces, good daylight and thermal conditions are important to promote the educational process, as unsatisfactory comfort levels can reduce physical and intellectual performance for both teachers and pupils. However, achieving successful classroom designs is rather complicated, as it requires the balancing of various interrelated factors, which is particularly challenging for hot and dry climates. In recent years, major improvements have been made in building optimization methods, and genetic algorithms used to search for high performing design solutions have shown their efficiency in solving such complex problems. This study shows how such an approach can be applied to optimize the thermal, lighting and energy performance of a middle school classroom in a hot and dry climate. Using a parametric approach and evolutionary multi-objective computation via Octopus plug-in for Grasshopper, various windows-to-wall ratios, wall materials, glass types, and shading devices were combined, to derive potential solutions that achieve a good balance between daylight provision and thermal comfort, while ensuring low energy consumption. The results show that improvements in useful daylight illuminance, adaptive thermal comfort and energy efficiency could be achieved through modification of building envelope parameters. Solutions for different building orientations are explored, providing recommendations for window-to-wall ratios in school buildings in a hot and dry climate. The results demonstrate how an optimization methodology can be used in the early stages of the building design process to understand how the building envelope can be tailored to ensure good building performance, both in terms of comfort and energy performance.
