-Those that reduce the energy demand of the property, i.e:

-Those that reduce non-renewable primary energy of the property, How can you achieve this?
-Replacing the gas or oil boiler with Aerothermy: Aerothermy: Installation and Maintenance Services - IBERDROLA
-Installing photovoltaic panels combined with another action from this list Install solar panels on your roof - IBERDROLA
-Replacing old air conditioning equipment (more than 10 years old) with more modern ones Air Conditioning Service - IBERDROLA
