Abstract

Conventional expertise-based approaches yield less-than-optimal window placement schemes (WPSs). The simulation-based window placement approaches (e.g., EnergyPlus) also suffer from being time-consuming. This study newly proposes a multi-objective window placement approach that can optimize WPSs under multiple objectives with high efficiency. It includes (i) transforming WPS-related building information from BIM's IFC to EnergyPlus's IDF, (ii) developing a surrogate model for WPS performance assessment, and (iii) optimizing WPSs under multiple objectives. The proposed approach is demonstrated using a dormitory building in Beijing, showcasing its ability to rapidly derive Pareto frontiers of optimized WPSs assuming different objective weightings. Compared to expertise-based methods, it shows a 30.66% and 16.47% performance enhancement for flexible-sized and fixed-sized window placements. Compared to simulation-based methods, it reduces time consumption by 98.10% while maintaining 94.3% accuracy in the case study. This study provides a well-performing and highly efficient window placement approach, making large-scale WPS optimizations feasible for designers.

使用BIM和代理模型的多目标窗口放置方法

传统的基于专家的方法产生的窗口放置方案（wps）不是最优的。基于模拟的窗口放置方法（例如EnergyPlus）也存在耗时的问题。本研究提出了一种多目标窗口放置方法，可以高效地优化多目标下的wps。它包括(i)将与WPS相关的建筑信息从BIM的IFC转换为EnergyPlus的IDF，（ii）开发WPS绩效评估的替代模型，以及（iii）在多个目标下优化WPS。以北京的一个宿舍楼为例，验证了该方法在不同目标权重下快速推导优化wps的帕累托边界的能力。与基于专业知识的方法相比，对于灵活大小和固定大小的窗口放置，它的性能提高了30.66%和16.47%。与基于仿真的方法相比，它减少了98.10%的时间消耗，同时在案例研究中保持了94.3%的准确率。本研究提供了一种性能良好且高效的窗口放置方法，使设计人员可以进行大规模的WPS优化。
