备注

BIPV的应用对降低建筑能耗和环境污染等问题具有重要作用.为研究BIPV在公共建筑中应用效果,对其进行项目后评价.首先根据BIPV项目特点,通过软件模拟、计算分析等方法对项目进行单项评价分析; 然后根据单项评价因素选取评价指标,建立评价指标体系,量化分析采集到的数据利用改进序关系法计算指标权重; 将云模型用于后评价,利用云模型代替隶属函数,对评价矩阵进行改进,实现评价指标与等级之间的可逆性映射; 最后通过实例说明模型的可行性,根据单项与综合评价结果有针对性的提出改进意见,以期为类似项目提供一定参考.
The application of BIPV plays an important role in reducing building energy consumption and environmental pollution. In order to study the application effect of BIPV in public buildings, post-project evaluation is carried out. Firstly, according to the characteristics of BIPV project, the project is evaluated and analyzed individually through software simulation, calculation analysis and other methods. Then the evaluation indexes are selected according to the single evaluation factor, the evaluation index system is established, and the collected data is quantified and analyzed to calculate the index weight by using the improved order relation method. The cloud model is used for post evaluation, and the evaluation matrix is improved by replacing the membership function with the cloud model, so as to realize the reversibility mapping between the evaluation index and the grade. Finally, an example is given to illustrate the feasibility of the model, and suggestions for improvement are put forward according to the results of individual and comprehensive evaluation, in order to provide some reference for similar projects.
