Obsolescencia de la envolvente térmica y acústica de la vivienda social de la postguerra española en áreas urbanas vulnerables. El caso de Zaragoza

In current Spanish cities, social housing built after the Civil War represents a widely spread building typology. In this paper we diagnose the physical obsolescence of the thermal and acoustic envelope of 21 residential units in less favoured urban areas of Zaragoza built in Spain’s post-war. The existing constructive solutions are defined, and their energy and acoustic behaviours are compared to current standards. It is observed that widows show poor performance regarding energy and acoustics, and that the opaque part of the envelope of these buildings is insufficient regarding energy standards, especially the roofs.
