The project concerns the energy upgrade of the 8th Florina Kindergarten through the installation of external thermal insulation and roof insulation and the installation of new frames made of metal aluminum frames with double glazing and thermal break. In order to upgrade the heat system, 16 kW of water air heat pumps shall be installed and the hot medium distribution system upgraded to control the temperature per area and per zone. Finally, energy savings will be enhanced by reducing by 66 % the installed power of the luminaires by replacing them with LED lighting.
