基于灰色聚类法的绿色建筑全寿命周期评价

Life Cycle Assessment of Green Buildings Based on Grey Clustering Method

基于推广和发展绿色建筑的宏观目标,建立了一套基于全寿命周期费用效益综合考虑下的实用可行、操作性强的绿色生态建筑评价标识体系。从绿色材料资源、水资源环境、能源与环境、室内环境质量、室外环境质量、运营管理、全寿命经济性方面,构建了改进后的评价指标体系,用AHP方法确定指标的权重,用灰色系统的评价方法对绿色生态建筑加以评价,并通过实例验证方法的实用性和科学性。由此可知,灰色聚类法在绿色生态建筑的评价中所得结果客观可靠,计算方法简单,具有很好的实用性和可操作性,建议利用计算机编程来优化评价程序,提高评价的效率与准确性。

To promote and develop green buildings,a standardized,applicable and easily operable index system for the assessment of such buildings was established on the basis of life cycle cost effectiveness.From the perspectives of environment-friendly materials,water resource environment,energy and environment,quality of indoor and outdoor environment,operation and management,and economical efficiency of life cycle,a modified index system was built,AHP was applied to obtain weights of indexes,evaluation methods of the gray system were used to evaluate green eco-buildings,case study was adopted to verify the practicability and scientificity of the method.The results showed that Grey Clustering was an objective and reliable tool to evaluate green buildings,the calculation was simple,practical and easily operable,and moreover,assessment process could be optimized by computer programming to improve the efficiency and precision of evaluation.
