Abstract

Purpose The paper aims to investigate the comfort-related performances of an innovative solar shading solution based on a new composite patented material that consists of a cement-based matrix coupled with a stretchable three-dimensional textile. The paper’s aim is, through a performance-based generative design approach, to develop a high-performance static shading system able to guarantee adequate daylit spaces, a connection with the outdoors and a glare-free environment in the view of a holistic and occupant-centric daylight assessment. Design/methodology/approach The paper describes the design and simulation process of a complex static shading system for digital manufacturing purposes. Initially, the optical material properties were characterized to calibrate radiance-based simulations. The developed models were then implemented in a multi-objective genetic optimization algorithm to improve the shading geometries, and their performance was assessed and compared with traditional external louvres and overhangs. Findings The system developed demonstrates, for a reference office space located in Milan (Italy), the potential of increasing useful daylight illuminance by 35% with a reduced glare of up to 70%–80% while providing better uniformity and connection with the outdoors as a result of a topological optimization of the shape and position of the openings. Originality/value The paper presents the innovative nature of a new composite material that, coupled with the proposed performance-based optimization process, enables the fabrication of optimized shading/cladding surfaces with complex geometries whose formability does not require ad hoc formworks, making the process fast and economic.
复杂建筑立面的定制遮阳解决方案:通过基于性能的生成设计,创新水泥-纺织品复合材料的潜力
本文旨在研究一种基于新型复合专利材料的创新遮阳解决方案的舒适性相关性能,该材料由水泥基基质和可拉伸的三维纺织品组成。该论文的目的是,通过基于性能的生成设计方法,开发一个高性能的静态遮阳系统,能够保证充足的日光空间,与室外的连接,以及从整体和以居住者为中心的日光评估的角度来看,一个无眩光的环境。设计/方法/方法本文描述了用于数字制造目的的复杂静态遮阳系统的设计和仿真过程。首先,对光学材料的性质进行了表征,以校准基于辐射的模拟。利用多目标遗传优化算法对模型进行优化,并与传统的外百叶窗和悬挑进行性能比较。研究结果:该系统展示了位于意大利米兰的一个参考办公空间,通过对开口形状和位置的拓扑优化,可以将有用的日光照度提高35%,减少高达70%-80%的眩光,同时提供更好的均匀性和与室外的联系。原创性/价值本文介绍了一种新型复合材料的创新性质,再加上所提出的基于性能的优化过程,可以制造具有复杂几何形状的优化阴影/包层表面,其可成形性不需要特别的模板,使该过程快速而经济。
