Indicators and Data in Spain Regarding an Overview of the Capacities in the Construction, Energy Efficiency and Renewable Energy Sector

Capacities of the construction sector are an important vector for a transition towards improving energy efficiency and the broader use of renewable energy in buildings. This affects not only the conventional renovation activity, but also the design and maintenance of buildings with advanced digital features to control their energy behavior. The present study aims to assess the data available on this topic in Spain at the national and regional scales (taking the regions of Aragon and the Basque Country as case studies) in order to be able to develop indicators to assess the building renovation policies effectiveness. The results show that Spain possesses ample data to assess the professional capacity of its sector, and the rough estimates shows existing skills are aligned with requirements, although it is crucial to ensure that university studies adapt to evolving sector needs. Yet emphasis on gathering data on smart technology adoption, engagement with energy communities, and administrative capacity is needed.
