Barcelona is a dense, compact city and only has urban land available (there is no developable land where it can grow). This makes it difficult for new houses or flats to be built in it and has caused its housing stock to age: the average age of its buildings are 65 years old and only 7% were constructed after 1980.

Bearing this reality in mind, the City Council has been implementing housing renovation policies for years. In the Climate Emergency Declaration, the objective of rehabilitating 10,000 properties a year is set out with subsidies and credits destined for energy rehabilitation.  

Beyond the environmental benefits, living in a property with decent energy conditions provides positive health effects and comfort for city residents.

Barcelona City Council provides assistance on an annual basis for the rehabilitation of properties aimed at the generation and saving of energy.
