A life cycle framework for a new integrated classification system for buildings and the identification of renovation strategies that lead to an optimal balance between reduction of seismic vulnerability and increase of energy efficiency, considering both economic losses and environmental impacts, is discussed through a parametric application to an exemplificative case-study building. Such framework accounts for the economic and environmental contributions of initial construction, operational energy consumption, earthquake-induced damage repair activities, retrofitting interventions, and demolition. One-off and annual monetary expenses and environmental impacts through the building life cycle are suggested as meaningful performance metrics to develop an integrated classification system for buildings and to identify the optimal renovation strategy leading to a combined reduction of economic and environmental impacts, depending on the climatic conditions and the seismic hazard at the site of interest. The illustrative application of the framework to an existing school building is then carried out, investigating alternative retrofitting solutions, including either sole structural retrofitting options or sole energy refurbishments, as well as integrated strategies that target both objectives, with a view to demonstrate its practicality and to explore its ensuing results. The influence of seismic hazard and climatic conditions is quantitatively investigated, by assuming the building to be located into different geographic locations.

通过参数应用讨论了一种新的建筑物综合分类系统的生命周期框架，并确定了在考虑减少经济损失和环境影响的同时，在减少地震脆弱性和提高能源效率之间实现最佳平衡的改造策略。一个示例性的案例研究大楼。这样的框架考虑了初始建设，运营能耗，地震引起的破坏修复活动，改造干预措施以及拆除对经济和环境的贡献。建议在建筑物生命周期中一次性支出和每年支出以及对环境的影响，作为有意义的性能指标，用于开发建筑物的集成分类系统并确定最佳的翻新策略，从而共同减少经济和环境影响，具体取决于感兴趣的地点的气候条件和地震灾害。然后对现有的学校建筑进行说明性的应用，研究替代性的改造解决方案，包括单独的结构改造方案或唯一的能源翻新方案，以及针对这两个目标的综合策略，以证明其实用性和可行性。探索其后续结果。
