It remains challenging to conduct an efficient dynamic façade design. In this article authors try to address this issue introducing the façade daylighting performance improvement (FDPI) indicator aimed to evaluate the performance of a dynamic (adaptive) façade from its daylighting performance point of view. To illustrate the FDPI application the authors introduced the preliminary dynamic façade concept for an office building located in Tel Aviv (Hot-summer Mediterranean Climate Csa) with further shape modification based on the daylighting performance analysis compared to the three alternatives representative of different typologies of dynamic facades. Al Bahr, One Ocean and The University of Southern Denmark façade systems were simulated under the same weather and building conditions of the preliminary dynamic façade concept and were considered as a benchmark for the study. The final dynamic façade concept elaborated by the authors in the preliminary comparative workflow showed noticeable daylight performance improvement with respect to the case studies comparative scenarios. The FDPI metric allowed to estimate a daylighting performance improvement of 43% of the final dynamic façade concept over the case study dynamic façade that showed the best performance in the daylighting simulations.

进行高效的动态立面设计仍然具有挑战性。在本文中，作者试图解决这个问题，引入了外墙采光性能改进 (FDPI) 指标，旨在从采光性能的角度评估动态（自适应）外墙的性能。为了说明 FDPI 应用，作者介绍了位于特拉维夫（炎热夏季地中海气候 Csa）的一座办公楼的初步动态立面概念，并根据采光性能分析与代表不同动态类型的三种替代方案进行了进一步的形状修改。外墙。阿尔巴尔，One Ocean 和南丹麦大学的立面系统在与初步动态立面概念相同的天气和建筑条件下进行了模拟，并被视为该研究的基准。作者在初步比较工作流程中阐述的最终动态立面概念显示，相对于案例研究比较场景，日光性能有显着改善。与在采光模拟中显示最佳性能的案例研究动态立面相比，FDPI 指标可以估计最终动态立面概念的采光性能提高了 43%。作者在初步比较工作流程中阐述的最终动态立面概念显示，相对于案例研究比较场景，日光性能有显着改善。与在采光模拟中显示最佳性能的案例研究动态立面相比，FDPI 指标可以估计最终动态立面概念的采光性能提高了 43%。作者在初步比较工作流程中阐述的最终动态立面概念显示，相对于案例研究比较场景，日光性能有显着改善。与在采光模拟中显示最佳性能的案例研究动态立面相比，FDPI 指标可以估计最终动态立面概念的采光性能提高了 43%。
