The main goal of this research is the proposal of an integrated approach, considering sustainability indicators related to energy life cycle of the building, for evaluation of energy efficiency measures with adaptation to climate change in Brazilian social housing projects. A Sustainability Index in the Energy Life Cycle was proposed that includes environmental, energy, economic and user thermal comfort indicators. A case study applied in the city of São Paulo, considered a representative project of the sector and cases with energy efficiency adaptation measures for three climate scenarios, considering climate change. The integrated approach highlighted the importance of the initial selection of materials, considering their associated impacts as well as the thermal and energy performance of the building during its life time, and the importance of climate change for the operational phase of the building. With the Sustainability Index in the Energy Life Cycle, large reductions were obtained comparing cases with adaptation measures to current practice. Results of this research contribute to improve project’s decisions with the incorporation of a holistic approach for the projects that are being produced for the housing deficit, considering better energy performance and lower resource consumption for users and the country in the long term.

这项研究的主要目标是提出一种综合方法的建议，考虑与建筑物能源生命周期相关的可持续性指标，以评估巴西社会住房项目中适应气候变化的能效措施。提出了能源生命周期中的可持续性指数，其中包括环境，能源，经济和用户的热舒适性指标。在圣保罗市进行的一项案例研究，考虑了气候变化，考虑了该行业的代表性项目以及针对三种气候情景采取能效调整措施的案例。综合方法强调了材料的初始选择的重要性，考虑了材料的相关影响以及建筑物在使用期内的热和能源性能，以及气候变化对建筑物运营阶段的重要性。通过能源生命周期中的可持续发展指数，与采用适应性措施的案例进行比较，可以大大降低能耗。这项研究的结果有助于通过结合整体方法解决住房短缺的项目，从而改善项目的决策，考虑到长期而言，能源性能的提高和用户和国家的能源消耗将减少。
