The eligible actions under this programme are:
- Actions for the improvement or rehabilitation of buildings of predominantly residential use for housing with the limits established in the Call Resolution, provided that a reduction of at least 30 % is obtained in the indicator of non-renewable primary energy consumption, referring to the energy certification.
- In buildings located in climate zones C, D and E, according to the climatic classification of the Technical Building Code, a reduction in the overall annual energy demand for heating and cooling of the single-family dwelling or building, as appropriate, of at least
- Climate zones D and E: a 35 %
- Climate zone C: a 25 %
- In the case of buildings subject to some level of protection because they are part of a declared environment or due to their particular architectural or historical value, in which actions on the elements that make up the thermal envelope are limited, it is not necessary to comply with the demand reduction requirement established in paragraph 2 of this article. However, those elements of the envelope on which intervention is possible must comply with the limit values of thermal transmittance and air permeability, where applicable, established in table 3.1.1.1.a¿HE1 and 3.1.3.a¿HE1, of Basic Document DB HE on Energy Saving of the Technical Building Code.
- In buildings in which energy efficiency improvement interventions have been carried out in the last four years in which it can be accredited that the overall annual energy demand for heating and cooling has been reduced by a percentage equal to or greater than that established in the Resolution of the call for applications, they are exempt from compliance with the requirement to reduce the overall annual energy demand for heating and cooling. When in said interventions, a reduction equal to or greater than the established percentage was not achieved, the requirement may be considered to be met if, with the joint consideration of the actions carried out in the aforementioned interventions and those carried out in the action that is the object of the application, the corresponding percentage of reduction in demand established is achieved, which must be accredited by means of the corresponding energy efficiency certification.
