The Spanish real estate stock is, on average, 45 years old and is at the bottom of the energy efficiency ranking, with an average rating of E, according to a study carried out by idealista, the main real estate marketplace in Spain, Italy and Portugalusing the certifications provided by its advertisers and the data from the Cadastre.
Even so, in the different Spanish provinces there are clear differences, possibly related to developmentalism and the impact of the 2007 crisis in each of them. The provinces of Toledo and Guadalajara could be considered ‘centenials’since the average construction date of their homes is after the year 2000 (2003 in Toledo and 2001 in Guadalajara), which has not served to improve their energy efficiency (E in both cases).
10 provinces have real estate parks built, on average, in the 1990s. In most of them, such as Almería, Segovia, Castellón, Huelva, Ciudad Real, Cuenca, La Rioja and Burgos, the energy rating is E, while in Soria and Lugo improves to D.
Most of the provinces (22) are made up of houses built in the 1980s. The most efficient, with D certification, are Huesca, Cáceres and Badajoz. The worst, with a G rating, are the two Canary provinces: Santa Cruz de Tenerife and Las Palmas. The rest have an E rating: Ávila, Cádiz, Albacete, Alicante, Granada, Murcia, Seville, Málaga, Ourense, Pontevedra, Girona, Lleida, Tarragona, Salamanca, Valladolid and A Coruña.
Another 15 provinces have parks built on average in the 1970s. Even so, the provinces of Palencia and Teruel share a D rating, while all the others drop to E: León, Navarra, Córdoba, Asturias, Álava, Cantabria, Zamora, the Balearic Islands, Valencia, Madrid, Vizcaya, Zaragoza and Guipúzcoa.
Barcelona is the only province with a park built on average in the 1960s, and it has an E energy rating.
Provincial capitals, from the newest to the oldest
Barcelona is the city with the oldest building stock, since it was built on average in 1945. It is followed by San Sebastián (1964), Madrid (1967) and Bilbao (1969), although in all four cases efficiency reaches E.
On the opposite side, the city with the most modern park is Ávila (energy rating E), which was built in 1995. It is followed by Badajoz (D) and Burgos (D), from 1993, as well as Albacete (E) and Huesca ( D) of 1992.
