高铁建筑表皮与光伏一体化设计分析

目前高铁建筑表皮与光伏一体化设计在形态上过于单一，限制了高铁建筑形式表达和更大生态节能效益的实现。基于对高铁建筑形态特征的分析，和对当前光伏组件性能的总结，探讨了在高铁建筑屋面、立面和构件系统中，创新光伏组件类型选择和集成模式的可行性。发现：①通过优化光伏组件类型的选择，可以将光伏组件转变成高铁建筑形式表达的积极要素；②随着光伏组件性能的提升，相关集成设计可以突破当前集中于屋面系统的现状，拓展到高铁立面、构件系统中。研究为进一步丰富高铁建筑表皮形式，扩大建筑光伏一体化应用规模提供了依据。

Analysis of Skin and Photovoltaic Integrated Design for High-Speed Railway Buildings

At present, the simple forms of BIPV (Building Integrated Photovoltaic) design for high-speed railway buildings restrict their creativity and ecological economy benefits. Based on an analysis of the morphological characteristics of high-speed railway buildings and the summary of current photovoltaic (PV) module performance, this study discusses the feasibility of selecting innovative PV module types and integrating roof, facade, and component systems. We found that: (1) PV modules can be transformed into positive elements which are expressed in the form of high-speed railway buildings through optimal selection; and (2) with the improvement of PV module performance, the BIPV design for high-speed railway buildings can expand to a facade and component system rather than being limited within the roof system. This study provides a basis for further enriching high-speed railway buildings and expanding the scale of BIPV systems.
