This operation is part of a general line of intervention in municipal buildings, in this case municipal civic centers (CCM) for the improvement of energy efficiency. According to the initial assessment of the condition of the buildings, the most appropriate actions will be carried out that contribute to improving the energy performance of the buildings. First, actions will be carried out that improve the physical conditions of the building (envelopes), and secondly the facilities that require it will be improved; finally, if appropriate, systems for measuring and controlling installations shall be installed.
