Efficient and sustainable housing
Renovation to improve the energy efficiency of the home
This line of subsidy is aimed at homeowners who wish to take measures to improve the energy efficiency of their habitual residence, such as modifying closures, replacing windows or air conditioning systems that replace fossil fuels with renewable energy or biomass.
These actions, in addition to the economic savings they bring in terms of energy consumption at home, will contribute to mitigating the effects of climate change and building a more sustainable city.
