Nowadays, the housing sector represents about 40% of the energy consumption in the European Union. In this regard, the level of insulation installed in buildings is directly related to the energy efficiency of the building, and consequently to the urban area. In addition, several studies have shown that a comprehensive perspective of energy efficiency is needed, together with calculating the importance of introducing Life Cycle Assessment (LCA) methodology. The purpose of this study is to develop a methodology to: first, measure the energy efficiency level of specific urban areas and their buildings using a geospatial model in an integral perspective; and second, the environmental impact caused by the refurbishment of these building façades using a LCA method. On the one hand, according to a bottom-up framework the quantitative and qualitative characterisation of the building stock façade at the urban scale is possible generating a georeferenced spatial data model of buildings using Geographic Information Systems. On the other hand, the environmental impact of the most usual constructive solutions to refurbishment building façades is calculated using the LCA methodology. The results obtained are merged and interpolated to the urban scale. The methodology is tested for the case study of blocks of flats in Barcelona using the open data of building stock from the Spanish Government. Firstly, this methodology provides more information in regard to urban areas as well as calculating their energy efficiency. Secondly, the study measures the renovation impact of the less efficient buildings. Finally, the results provide the basis for supporting decisions on building stock retrofitting for urban scale from a new approach, especially making the selection between various renovation scenarios much clearer. 000063135 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000063135 592__ $$a0.172$$b2017 000063135 593__ $$aGeography, Planning and Development$$c2017$$dQ3 000063135 593__ $$aRenewable Energy, Sustainability and the Environment$$c2017$$dQ4 000063135 593__ $$aManagement, Monitoring, Policy and Law$$c2017$$dQ4 000063135 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063135 700__ $$0(orcid)0000-0002-7660-3508$$aSierra-Pérez, Jorge 000063135 700__ $$aBoschmonart-River, Jesús 000063135 700__ $$aLladó Morales, Gil 000063135 700__ $$aRomero Cálix, Ana 000063135 7102_ $$15010$$2815$$aUniversidad de Zaragoza$$bUnidad Predepartam.
