The need to reduce the impact of building projects on the sustainability of the built environment and improve the use of resources necessitated several interventions such as the development of methods to assess building impacts and improve the sustainability performance of buildings. Using the BSAM scheme – a green building rating system developed specifically for the sub-Saharan region of Africa, the generalized Choquet fuzzy integral method was employed to determine the importance weights of the sustainability assessment criteria. Data collected from industry experts form the base inputs for the impact of the various sustainability criteria based on the local variations. Consequently, the building sustainability evaluation index and grading scheme were developed to measure and evaluate the sustainability performance of buildings. The developed sustainability rating model was validated in four real-world case studies to demonstrate its usefulness and robustness in practice. The findings revealed that the conventional approach of aggregation of points used by the existing green rating tools is less effective in dealing with criteria that have interactive characteristics. Also, assessment criteria such as sustainable construction practices, transportation, and energy have a significant impact on the sustainability of buildings. The study provides substantial contributions to the existing body of knowledge about green building assessment systems for built environment stakeholders, both from the theoretical and practical perspectives.

为了减少建筑项目对建筑环境的可持续性的影响并改善资源的利用，需要采取多种干预措施，例如开发评估建筑影响的方法和改善建筑的可持续性表现。使用BSAM方案-专为非洲撒哈拉以南地区开发的绿色建筑评级系统，采用了通用的Choquet模糊积分方法来确定可持续性评估标准的重要性。从行业专家那里收集的数据构成了基于本地变化而产生的各种可持续性标准影响的基础输入。因此，制定了建筑物可持续性评估指标和分级方案，以衡量和评估建筑物的可持续性表现。在四个实际案例研究中验证了已开发的可持续性评级模型，以证明其实用性和鲁棒性。调查结果表明，现有的绿色评级工具使用的传统积分方法在处理具有交互特征的标准时效果较差。此外，诸如可持续建筑实践，运输和能源之类的评估标准对建筑物的可持续性也有重大影响。该研究从理论和实践的角度为现有的有关建筑环境利益相关者绿色建筑评估系统的知识体系做出了重大贡献。调查结果表明，现有的绿色评级工具使用的传统积分方法在处理具有交互特征的标准时效果较差。此外，诸如可持续建筑实践，运输和能源之类的评估标准对建筑物的可持续性也有重大影响。该研究从理论和实践的角度为现有的有关建筑环境利益相关者绿色建筑评估系统的知识体系做出了重大贡献。调查结果表明，现有的绿色评级工具使用的传统积分方法在处理具有交互特征的标准时效果较差。此外，诸如可持续建筑实践，运输和能源之类的评估标准对建筑物的可持续性也有重大影响。该研究从理论和实践的角度为现有的有关建筑环境利益相关者绿色建筑评估系统的知识体系做出了重大贡献。和能源对建筑物的可持续性产生重大影响。该研究从理论和实践的角度为现有的有关建筑环境利益相关者的绿色建筑评估系统的知识体系做出了重大贡献。和能源对建筑物的可持续性产生重大影响。该研究从理论和实践的角度为现有的有关建筑环境利益相关者绿色建筑评估系统的知识体系做出了重大贡献。
