“效益—产量”视角下绿色建筑灰色关联评价模型

A benefit-output model for measuring the performance of green buildings using grey relational algorithm

在当前大力应用并发展绿色建筑的背景下,科学合理地量化绿色效益已成为政府制定节能减排政策和企业拟定竞争战略的基石。文中通过识别多维的评价指标,构建由实物及货币指标组成的"效益-产量"模型,采用组合权重的灰色关联分析法,对建筑工程项目的绿色效益进行多方案量化评比。通过3个中国实例测算对比发现:"效益-产量"视角下灰色关联评价模型比灰色聚类评估、数据包络分析等方法更加稳定、可靠、有效,也更能反映绿色建筑的多维含义。

Recent years have witnessed a wide application of green buildings in the world.Properly measuring the performance of green building projects has been the cornerstone of governmental policy-making on energy saving and carbon reduction,and it has been playing a crucial role in the formulation of business competitive strategies.In this study,multidimensional evaluation indicators are identified.A benefit-output model composed of physical and currency indicators is proposed using gray relational algorithm to make quantitative evaluation of multiple schemes for green benefit of construction projects.Through the comparison of three cases in China,the proposed model is found to be more stable,reliable,and effective than others including grey cluster evaluation and data envelope analysis,presenting a multi-dimensional concept of green buildings and offering a useful framework for application in other contexts.
