The proposed project concerns the implementation of targeted energy upgrading and energy saving interventions (ETS-Energy Category 1), as well as demonstration action to exploit Renewable Energy Sources (RES Energy Category 2), which will make a decisive contribution to:          Improving the energy efficiency of the reference building and the hospital as a whole;          Limiting the energy footprint of the building and the hospital as a whole;          Significant savings on an annual basis by reducing energy costs;          The protection of the environment;          Raising public awareness;          The creation of appropriate conditions of comfort and the provision of nursing work;          Reduction of faults and increased reliability of key facilities;          The encouragement of other public administration bodies to carry out similar projectsAfter the implementation of the interventions the hospital building will be classified in category B (upgrading by 2 categories). The achieved primary energy savings will be 43.80 %.
