Within the Energy Performance of Buildings Directive information symmetry regarding financial and environmental benefits, coming from real estate performance, is a key element in the promotion of efficient buildings. However, the link between energy efficiency and its perceived co-benefits is far from perfect in EU countries with a short trajectory in the promotion of such residential attributes, endangering the efficacy of information-symmetry policies. Using a large survey applied to sellers, buyers, lessors and tenants this paper explores, in Spain, the perceived co-benefits in terms of energy savings and thermal comfort of efficient homes and whether such perception correlates to current living conditions, housing tenure and sociodemographic profile of respondents. Results suggest that in general such co-benefits are present in the mind of the main agents of the housing market. However, their perception is far from being homogeneous, it is clearer in the case of households whose current home is poorly insulated or inadequately serviced in terms of thermal active systems. Sociodemographic conditions also play a role in co-benefits perceptions: Elder, wealthier and landlords, irrespective of whether they act as sellers, buyers or lessors, do perceive to a larger extent the co-benefits of efficient homes. Such findings signal clear paths for the improvement of energy and housing policy.

在西班牙住宅市场中能效的感知收益及其与社会人口和居住条件的关系

在《建筑物的能源绩效指令》中，房地产绩效带来的有关财务和环境效益的信息对称性是促进高效建筑的关键要素。但是，在欧盟国家中，能源效率与其可感知的共同利益之间的联系还远非完美无缺，在促进此类居住属性方面发展的轨迹很短，危及信息对称政策的有效性。本文使用针对卖方，购买者，出租人和租户的大规模调查，在西班牙探索了节能住宅和高效住房的热舒适性方面的共同利益，以及这种看法是否与当前的居住条件，住房使用权和社会人口统计学相关受访者的个人资料。结果表明，这种共同利益通常存在于房地产市场主要代理商的脑海中。但是，他们的看法远非同质，就热绝缘系统而言，当前房屋的隔热性差或服务不足的家庭更清楚。社会人口条件在共同利益观中也起着作用：老年人，富人和房东，无论他们是作为卖方，购买者还是出租人，都在更大程度上感知到了高效住房的共同利益。这些发现为改善能源和住房政策指明了清晰的道路。对于热绝缘系统而言，当前房屋的隔热性差或服务不足的家庭更明显。社会人口条件在共同利益观中也起着作用：老年人，富人和房东，无论他们是作为卖方，购买者还是出租人，都在更大程度上察觉到了高效住房的共同利益。这些发现为改善能源和住房政策指明了清晰的道路。对于热绝缘系统而言，当前房屋的隔热性差或服务不足的家庭更明显。社会人口条件在共同利益观中也起着作用：老年人，富人和房东，无论他们是作为卖方，购买者还是出租人，都在更大程度上感知到了高效住房的共同利益。这些发现为改善能源和住房政策指明了清晰的道路。
