Eficiencia energética de fachadas ventiladas activas aplicadas a edificios de oficinas en España

Resumen

This work analyses the energy efficiency of a Ventilated Active Façade VAF applied to office buildings in Spain in comparison with conventional façades that comply the minimum energetic requirements of the Spanish Technical Building Regulation (Código Técnico de la Edificación - CTE). The analysis considers the climatic diversity of the 12 climatic zones of Spain. The studied VAF is made of an outer layer element of 2mm galvanized steel panels and a 3cm air cavity where the ventilation air is preheated in winter and exhausted in summer. After defining 8 typical office typologies in Spain, 192 study cases are obtained where different parameters like the percentage of glass in façade, the orientation and the climatic zone of the buildings are considered. The energy demand of all these study cases is obtained using the official simulation tool of the CTE called LIDER.
