摘要

本研究旨在通过优化程序,在与光架系统集成的全玻璃立面的工作平面环境中实现日光可用性的平衡,该优化程序可以帮助建筑师评估多种设计方案的采光性能,并构建优化设计。该方法使用参数化设计、模拟建模和遗传算法。以一个典型的办公室为例,测试和验证了轻型货架系统优化程序的有效性。在马来西亚的天空条件下,在两个太阳至点(6月和12月)和3月的一个春分对光架设计的五个参数进行了优化。优化结果表明,光架参数的优化设计方案具有很大的提高照度的潜力。优化后,与参考模型相比,有用日光照度的采光性能在6月21日分别提高了15.6%和4.7%,在3月21日提高了17.5%和5.8%,在12月21日增加了5.8%和11.3%。通过统计分析研究了最优设计方案的性能指标与其他情况之间的关系,结果表明,回归分析表明,该方案具有较高的可靠性以及不同水平的变异系数。©2020作者。由solarlists.com发布。这是一篇基于CC by许可证的开放访问文章(https://creativecommons.org/licenses/by/4.0/)。

Optimization of Daylight Performance Based on Controllable Light-shelf Parameters using Genetic Algorithms in the Tropical Climate of Malaysia
This study aims to achieve a balance of daylight availability in the work-plane environments of a fully glazed facade integrated with a light shelf system using an optimization procedure that can assist architects with assessing the daylighting performance of numerous design alternatives, and build-up the optimized design. The approach uses parametric design, simulation modelling, and genetic algorithms. A case study of a typical office is carried out to test and verify the effectiveness of the optimization procedure for a light shelf system. Five parameters of light shelf design are optimized in two solar solstices (June and December) and one equinox in March under the Malaysian sky conditions. The optimization results indicate that the optimal design options of light-shelf parameters have great potential for illuminance improvement. After the optimization, the daylighting performance of useful daylight illuminance compared to reference models is increased respectively with an average value of 15.6% and 4.7% on the 21st of June, and by 17.5% and 5.8% on 21st of March, and by 5.8% and 11.3% on 21st of December. Statistical analysis is achieved to investigate the relationship between the performance metric of the optimal design options and the other cases, the outcomes showed that the regression analysis indicated a high level of reliability as well as different levels of variation coefficients. © 2020 The Author(s).
