Energy renovation of post-World War II private multifamily residential buildings has been identified to have a great deal of energy-saving potential but faces a great challenge across Europe, and especially in South Europe, due to fragmented property structures and longer return periods in energy efficiency investments. However, there is great deal of potential in activating demand aggregation in areas with homogeneous typologies. Local authorities play a key role in leading district-scale renovation but lack adequate methods for analysing and prioritizing areas from an integrated perspective, including social aspects. The methodology presented in this paper aims to support local authorities by providing a tool for the diagnosis and prioritization of homogeneous groups of residential buildings to address their renovation based on an analysis of their needs and opportunity factors. First, the methodology sets the universe of analysis; second, based on indicators, it provides comparative information within the municipality, which leads to a prioritization of areas for building renovations according to the state of the building and to the socio-economic profile of the residents; lastly, a detailed diagnosis of selected groups is performed, providing information to design the Renovation Action Plans accordingly. The application of the methodology in Basauri is presented in this paper.

Despite its proven potential for systemic change, large-scale investment (both public and private) in sustainable homes still faces barriers, often caused by insecurity about personal, societal and financial returns on investment and a lack of clarity about concrete elements of sustainable age-friendly living environments and the choice of building, retrofitting and adaptation measures to be implemented. The projects that contributed to this workshop are developing solutions to tackle these barriers and propose a holistic and integrated approach to progress on implementation.

Asumiendo que la financiación es una cuestión clave para impulsar las actuaciones de rehabilitación y regeneración urbana en el actual contexto económico, se analizan una serie de casos, nacionales e internacionales, para evaluar qué nuevos enfoques pueden servir para construir fórmulas innovadoras, de gestión y financiación, que impulsen este tipo de intervenciones en el contexto español. Del análisis de los casos, se define un conjunto de recomendaciones resumidas en torno a tres ejes: marco estable y flexible de financiación pública, complementariedad de la financiación pública y privada, y énfasis en la comunicación, intermediación y facilitación de los procesos.

En el marco de la Agenda Urbana Española desarrollada por el Ministerio de Transportes, Movilidad y Agenda Urbana, el Ayuntamiento de Castelló de la Plana fue elegido en 2021 como municipio piloto para la elaboración de su Plan de Acción Local de la Agenda Urbana. A través de este artículo se expone de manera sintética el proceso realizado en el municipio de Castelló para la traslación de la metodología desarrollada a nivel estatal a su contexto local, con el objetivo de poder definir su propia Agenda Urbana incluyendo el Plan de Acción Local como instrumento estratégico y operativo para la transformación urbana municipal.
