Climate-responsive facades (CRFs) present a new paradigm for high-performance building façade design as they provide a dynamic response to exterior environmental loads. CRFs represent a new approach compared to typical façades constructed as static barriers with a fixed performance to separate the indoor and outdoor conditions. CRFs regulate the multiple environmental loads simultaneously through dynamic responses of different components. This study aims to develop a pre-design tool to support the selection of suitable technologies to create multifunctional CRFs. The proposed framework includes five steps that lead to a qualitative assessment of the façade requirements based on quantitative metrics. These steps include defining the objectives of a CRF, setting performance constraints based on environmental and building contexts, defining a responsive operation scenario, selecting the most suitable technology, and finally creating a conceptual design of the CRF. The application of the framework is verified in designing a transparent and opaque CRF module based on the layout of a ventilated cavity Trombe wall. The discussion section shows that the specific metrics in the framework and their quantitative ranges are generalizable and can be adjusted to match case-specific architectural, environmental, and technical criteria. The applicability of the framework for the early decision-making stages of façade design is finally discussed, looking at the future steps for better integration of climate-responsive materials.

开发基于性能的多功能气候响应立面设计框架

气候响应型立面(CRF)为高性能建筑立面设计提供了新的范例,因为它们可以动态响应外部环境负荷。与典型的立面相比,CRF代表了一种新方法,该立面构造为具有固定性能以分隔室内和室外条件的静态屏障。CRF通过不同组件的动态响应同时调节多个环境负荷。这项研究旨在开发一种预设计工具,以支持选择合适的技术来创建多功能CRF。拟议的框架包括五个步骤,可基于定量指标对立面要求进行定性评估。这些步骤包括定义CRF的目标,根据环境和建筑环境设置性能约束,定义响应式操作方案,选择最合适的技术,最后创建CRF的概念设计。该框架的应用在根据通风腔Trombe壁的布局设计透明和不透明的CRF模块时得到了验证。讨论部分显示,框架中的特定指标及其定量范围是可概括的,可以进行调整以匹配特定于案例的体系结构,环境和技术标准。最后讨论了立面设计早期决策阶段的框架适用性,着眼于更好地整合气候响应性材料的未来步骤。该框架的应用在根据通风腔Trombe壁的布局设计透明和不透明的CRF模块时得到了验证。讨论部分显示,框架中的特定指标及其定量范围是可概括的,可以进行调整以匹配特定于案例的体系结构,环境和技术标准。最后讨论了立面设计早期决策阶段的框架适用性,着眼于更好地整合气候响应性材料的未来步骤。该框架的应用在根据通风腔Trombe壁的布局设计透明和不透明的CRF模块时得到了验证。讨论部分显示,框架中的特定指标及其定量范围是可概括的,可以进行调整以匹配特定于案例的体系结构,环境和技术标准。最后讨论了立面设计早期决策阶段的框架适用性,着眼于更好地整合气候响应性材料的未来步骤。和技术标准。最后讨论了立面设计早期决策阶段的框架适用性,着眼于更好地整合气候响应性材料的未来步骤。和技术标准。最后讨论了立面设计早期决策阶段的框架适用性,着眼于更好地整合气候响应性材料的未来步骤。
