Improving the energy efficiency of existing buildings in favor of reducing consumer demand and associated emissions is one of the central strategies for achieving global GHG (greenhouse gas) emissions reduction targets. Contemplating this activity within the paradigm of long-term sustainability implies, on one hand, that project intervention strategies must be assisted by tools that integrate social, environmental, and economic indicators that must be evaluated from an LCA (life cycle assessment) perspective and, on the other hand, deviations must be considerate of the energy-saving projections that are sought to be achieved through the potential strategies to be implemented. This article develops an LCA methodology whose objective is to evaluate the comprehensive sustainability of existing passive strategies in the local industry through the quantification of environmental and economic indicators throughout different climatic scenarios, which are socially contextualized for a building existing in a Mediterranean region. Part of the results obtained showed a loss of the effectiveness of measurements with an adequate response to the current climatological reality.

气候变化视角下废弃建筑热围护结构再生作用的综合可持续性评估

提高现有建筑的能源效率以减少消费者需求和相关排放是实现全球温室气体（温室气体）减排目标的核心战略之一。在长期可持续性范式内考虑这项活动意味着，一方面，项目干预策略必须得到整合社会、环境和经济指标的工具的帮助，这些指标必须从 LCA（生命周期评估）的角度进行评估，并且，另一方面，偏差必须考虑到通过潜在战略实现的节能预测。本文开发了一种 LCA 方法，其目标是通过量化不同气候情景中的环境和经济指标来评估当地工业现有被动战略的全面可持续性，这些指标与地中海地区现有的建筑物具有社会背景。获得的部分结果表明，由于对当前气候现实的充分反应，测量的有效性有所下降。
