From an energy point of view, work is mainly done on the envelope, implementing the building's energy efficiency through the installation of a ventilated wall that allows for both insulation and ventilation, with a clear improvement in the indoor climate in both the summer and winter months; in addition to this work, the basement rooms will be clad with insulation combined with plasterboard.

It should be noted that the choice of ventilated walls is also a way to improve the conservation of the wall faces, protecting them from atmospheric agents and thus guaranteeing an extension of the building's life, as well as a not inconsiderable improvement in terms of aesthetics and functionality
