光伏建筑一体化光伏幕墙体系与经济性研究

Photovoltaic Building Integrated Photovoltaic Curtain Wall System and Economic Research

在当今全球能源转型的大背景下,建筑行业作为主要能源消费领域,其能源消费模式的革新对于实现国家层面的可持续发展目标至关重要。鉴于此,显著削减建筑领域对化石燃料的依赖,并积极拓宽可再生能源的利用渠道,成为了推动绿色建筑革命的重要策略。光伏建筑一体化(BIPV)技术,作为一种将高效光伏发电系统与现代化建筑设计、建造工艺深度融合的创新实践,不仅展现了太阳能这一清洁、可再生资源的巨大应用潜力,而且也预示着未来建筑领域在能源自给自足方面广阔的发展蓝图。为了探究光伏建筑一体化的现状,文章对光伏建筑一体化的背景及常用的应用场景进行研究,通过案例分析光伏幕墙增量成本,并采用静态投资回收期和效益费用比两个参数对薄膜类光伏幕墙、晶硅类光伏幕墙、薄膜类光伏采光顶三种光伏方案的经济性进行分析,为后续光伏建筑一体化中光伏幕墙的经济性提供参考。

Against the backdrop of the global energy transition,the construction sector,as a leading consumer of energy,plays a pivotal role in achieving national sustainability goals,rendering the transformation of its energy consumption patterns imperative.Accordingly,a substantial reduction in the reliance on fossil fuels within the construction sector,coupled with proactive expansion of renewable energy sources,constitutes a central strategy driving the green building revolution.Building Integrated Photovoltaics(BIPV)technology,an innovative practice that deeply integrates high-efficiency photovoltaic power generation systems with modern architectural design and construction techniques,not only showcases the immense application potential of solar energy,a clean and renewable resource,but also heralds a broad development prospect for the future of self-sufficient buildings in the architectural domain.In order to investigate the current situation of BIPV,this article studies the background and common application scenarios of photovoltaic building integration.Through case analysis of incremental cost of photovoltaic curtain wall,this article adopts two parameters,static investment return period and benefitcost ratio,and makes economic analysis of three photovoltaic schemes:thin film photovoltaic curtain wall,crystalline silicon photovoltaic curtain wall and thin film photovoltaic daylighting roof.It provides references for the economy of photovoltaic curtain wall for future BIPV development.
