In southern European countries, summer temperatures could contribute to a high cooling energy consumption. Family units with fewer economic resources living in social dwellings could suffer from fuel poverty if they want to use air conditioning systems. Otherwise, they could face discomfort hours because of a natural ventilation without clear control criteria. This study analyses quantitatively and qualitatively the possibilities of natural ventilation through mixed-mode and the possibility of reducing fuel poverty for family units living in social dwellings. For this purpose, the application of a natural ventilation approach was analysed through an adaptive behaviour based on EN 16798-1: 2019. A case study of 51 social dwellings was analysed by using various operation hypothesis between 2015 and 2019. The results showed the potential of using mixed-mode approaches based on the categories from EN 16798-1:2019 to achieve savings in the energy consumption and to remove cases of fuel poverty in low-income families. Likewise, surveys in which families living in these cities participated reflected the great awareness of the natural ventilation use, although there is not a clear criterion of the need of this ventilation for thermal comfort, as well as the need of a supportive use of air conditioning systems. Finally, the similarity of the climate conditions of the city analysed and the coastal cities from various countries in the south of Europe shows the possibility of using ventilation strategies as energy saving measures in other regions.
在欧洲南部国家，夏季气温可能导致较高的制冷能耗。居住在社会住房中的经济资源较少的家庭单元，如果想要使用空调系统，可能会面临能源贫困问题。否则，由于自然通风缺乏明确的控制标准，他们可能会面临不适时段。本研究对混合模式下自然通风的可能性以及居住在社会住房中的家庭单元减少能源贫困的可能性进行了定量和定性分析。为此，通过基于EN 16798-1:2019的适应性行为分析了自然通风方法的应用。通过对2015年至2019年间51个社会住房的案例研究，采用了各种运行假设进行分析。结果表明，基于EN 16798-1:2019的类别使用混合模式方法具有在能源消耗方面实现节约并消除低收入家庭能源贫困案例的潜力。同样，居住在这些城市的家庭参与的调查反映出对自然通风使用的高度认识，尽管对于热舒适而言，自然通风的需求并没有明确的标准，以及对辅助使用空调系统的需求。最后，所分析城市与欧洲南部各国沿海城市气候条件的相似性表明，在其他地区将通风策略用作节能措施具有可能性。
