Energy saving and generation renovations

We will help you to be more energy efficient and to generate your own power using solar energy.

Improving energy efficiency for a better life

Energy-saving renovation is a strategic sector that must be promoted, because living in a home with good energy conditions has a positive effect on people's health.

The 2017 grants campaign promotes actions to foster energy efficiency, such as reducing energy consumption through exterior insulation of the building and promoting the use of solar energy.

In order to foster the generation of solar energy, subsidies of up to 60% of the total cost of the work are available (for both individual and owner-community applications) and a 50% subsidy for overall energy-improvement actions.

Furthermore, 100% of the cost of the energy audit will be financed, provided that any of the actions considered in the audit are then carried out. 100% financing of the cost of the technical project or report will also be provided for measures concerning energy generation and reducing energy consumption, provided that the installation is carried out.

What buildings and homes can benefit from these grants?

The grants are aimed at housing used as permanent habitual residences and at apartment buildings where 70% of the building's surface area - excluding the ground floor - is used as habitual residences.

If the homes are empty, the grants will only be awarded where the owner makes a commitment to include the property in the Barcelona Rented Housing Pool once it has been renovated.
