摘要
利用建筑光伏一体化(BIPV)来利用可再生能源的方法受到了各国政府大力的支持和推广,但不能忽视的是不分条件盲目采用BIPV将会导致对环境的负面影响。本文采用全生命周期分析的方法分析了太阳能光伏板生产含能与不同应用条件下的收益,剖析了当前在BIPV的推广中存在的一些误区,指出正确运用BIPV以及在建筑里利用太阳能的策略和方法,避免不适当的应用导致对环境的负面影响。此外,分析了在中国实现"零能耗"建筑的可行性,指出"零能耗"建筑推广的正确途径是面向农村住宅而非城市建筑。
Building Integrated Photovoltaic system (BIPVs) is a measure of utilizing renewable energy, and has received great attention from researchers and powerful financial support by government. As a result, it has been widely promoted into application and some demonstration projects have been built. This paper is to point out that improper applying BIPVs will cause negative environmental impact. The embodied energy of photo voltaic panel in its life cycle and possible yielded energy during operation period in different application conditions are analyzed. According to this analysis, the application strategies to avoid the negative environmental impact of BIPV in China have been proposed. The feasibility of zero-energy building in China is analyzed as well, and it is concluded that zero-energy building is only viable in rural China rather than in urban China.
