如果不大力改善广泛的住宅存量，欧盟2020年的新能源目标就不可能实现。在这张全景图中，提出现有住宅建筑的分析和能源评估程序非常重要，以便有助于其改造、减少消耗和提高热舒适度。南欧夏季气候条件下的特定能源行为，即高温和太阳辐射，导致需要不同的干预机制来节能和改善室内舒适度，但迄今为止，这些方面尚未得到广泛的分析或评估。本文的主要目的是为西班牙南部地中海地区住宅区的改造提供被动干预策略的案例研究。该案例研究是一座最近修复的建筑，拥有 68 个社会住房单元。对建筑围护结构的改造改善了外墙和窗户的隔热效果，纳入了遮阳功能并提高了气密性水平，与原始状态相比，总需求显着减少（约38%），主要改善了室内舒适度并减少了能源匮乏的发生。
The new energy objectives of the EU for 2020 will not be possible unless the extensive residential stock is improved energetically. In this panorama it is very important to propose procedures for the analysis and energy assessment of existing residential buildings in order to contribute to their retrofitting, cutting down consumption and improving thermal comfort. The specific energy behaviour in the summer climate conditions of southern Europe, with high temperatures and solar radiation, results in a need for different intervention mechanisms for energy saving and improvement of indoor comfort, aspects which have not been widely analyzed or assessed to date. The main aim of this paper is to offer a case study with passive intervention strategies for the retrofitting of the residential sector in the Mediterranean area of southern Spain. The case study is a recently restored building with 68 social housing units. The retrofitting intervention on the building envelope improved insulation in facades and windows, incorporated solar protection and increased the level of airtightness, bringing about a notable reduction (around 38%) of the total demand compared to its original condition, leading primarily to improved indoor comfort and a lower occurrence of energy poverty.
