The project concerns the implementation of integrated interventions for the energy upgrading of the closed gym of Ierapetra “Markos Foniadakis”. It supports the smart management of energy and the use of Renewable Energy Sources in public infrastructure while saving energy.The envisaged interventions concern:- Installation of photovoltaic panels on the roof of 10 kw. The photovoltaic system will be connected to the public electricity network by netting the energy generated (net metering).- Replacement of the lamps of the room (~38 kW) and the remaining spaces (~3.16 kW) with LED lighting (16.87 kW).- Capacity of the panel with aluminium film coating for the improvement of the energy efficiency of the building.
