The project concerns the improvement of the energy behaviour of the building, with a total surface of 1558,02 sq.m., built in the year 1955. Taking into account the thermophysical properties of building materials of the building shell, the systems and given that the building is not thermally insulated, is classified in the category “H” with primary energy consumption 288,7Kwh/m²/year. The interventions that will be carried out will upgrade and classify the building in category “D”, with primary energy consumption 141,90Kwh/m²/year. In other words, primary energy savings amount to 50.9 %.
