Abstract Recently, architectural designs with dynamic facades have been introduced as a strategy for improving building environmental performance. Currently, such as those capable of rotation and folding motion, are widely used. An investigation of the effect of these two motions on the energy and daylight performance can contribute to enhanced energy efficiency and occupant comfort. Therefore, a parametric simulation approach was implemented for the design optimisation of dynamic facades capable of two motions in a high-rise tropical office building near the Equator. 72 cases representing the two motions and different transmittance values, axes, and dimensions were compared for determining the best compromise between minimum energy consumption and maximum daylight comfort. The results indicate that energy consumption can be decreased by 14–21% through the implementation of dynamic facade compared with base case. The folding motion exhibits better performance in all four orientations than the rotation motion. For daylighting, the area of adequate illuminance increases by 15–32% with the optimal configuration. The value obtained for the rotational motion exceeds that for the folding motion. Based on the overall optimal solutions in terms of energy and illuminance performance, the optimal design for all orientations corresponds to the rotation motion. Furthermore, the results indicated that optimal angles are concentrated within a certain range that typically corresponds to 15° from the fully open position. This study provides a performance-based approach to aid designers in making decisions in the early design stage, from the energy and visual comfort perspectives, and not simply from the aesthetic viewpoint.

两种运动类型对动态立面太阳透射率和日光性能的影响

摘要 最近，动态立面的建筑设计被引入作为改善建筑环境性能的策略。目前，诸如能够旋转和折叠运动的那些被广泛使用。研究这两种运动对能源和日光性能的影响有助于提高能源效率和乘员舒适度。因此，在赤道附近的热带高层办公楼中，采用参数化模拟方法对能够进行两种运动的动态立面进行设计优化。比较了代表两种运动和不同透射率值、轴和尺寸的 72 个案例，以确定最低能耗和最大日光舒适度之间的最佳折衷方案。结果表明，与基本情况相比，通过动态立面的实施，能耗可以降低 14-21%。折叠运动在所有四个方向上都比旋转运动表现出更好的性能。对于采光，在最佳配置下，足够的照度面积增加了 15-32%。旋转运动获得的值超过折叠运动的值。基于能量和照度性能的整体优化方案，所有方向的优化设计对应于旋转运动。此外，结果表明最佳角度集中在某个范围内，该范围通常对应于完全打开位置的 15°。这项研究提供了一种基于性能的方法来帮助设计师在早期设计阶段做出决策，
