The practice of sustainable buildings has become a general trend in urban development. Yet, with the rapid development of urban renewal, the performance of existing buildings often fails to meet the actual needs of sustainable urban development. To improve the performance of existing buildings, it is urgently needed to transform the existing structures and upgrade their functions and facilities. However, the pertinent guidelines have often been unclear for assessing the performance of existing structures, and a sounder and quantitative sustainable performance assessment approach has been lacking to guide decisions on the restoration, protection, or demolition of existing buildings. Based on a multi-expert consultation methodology, we proposed a revised flexible comprehensive assessment system and a comprehensive sustainability assessment approach. The system includes 4 categories, 7 quantitative and 47 qualitative indicators. Specifically, the assessment system involves a series of steps: 1) building a hierarchical model, 2) defining assessment indicators/items and constructing a judgment matrix, 3) determining the weight coefficients of the indicators, 4) collecting/calculating quantitative and qualitative data, 5) analyzing the data and results, and 6) drawing the assessment conclusions. A case study was presented to demonstrate the application of the approach. Compared to current practices, this comprehensive assessment system may serve as a scientifically sounder and quantitative approach to guide sustainable development of existing urban buildings.
可持续建筑实践已成为城市发展的普遍趋势。然而，随着城市更新的快速发展，现有建筑的性能往往无法满足可持续城市发展的实际需求。为提高现有建筑的性能，迫切需要改造现有结构并升级其功能和设施。然而，在评估现有结构的性能方面，相关指导方针往往不够明确，缺乏更完善的定量可持续性能评估方法来指导有关现有建筑修复、保护或拆除的决策。基于多专家咨询方法，我们提出了一种修订后的灵活综合评估系统和一种全面的可持续性评估方法。该系统包括4个类别、7个定量指标和47个定性指标。具体而言，评估系统涉及一系列步骤：1）构建层次模型；2）定义评估指标/项目并构建判断矩阵；3）确定指标的权重系数；4）收集/计算定量和定性数据；5）分析数据和结果；6）得出评估结论。通过一个案例研究展示了该方法的应用。与当前做法相比，这种综合评估系统可作为一种更科学合理的定量方法，以指导现有城市建筑的可持续发展。
