Efficiency improvement consists in the elimination of gas oil plants, including the inerting of tanks containing gas oil for heating and the creation of 2 thermal plants, to replace the existing ones, located in: Staircase A – heat pumps with a global potential of 90 thermal kW; Staircase B – heat pumps with a global potential of 90 thermal kW and microgenerator with a potential of 34 thermal kW and 15 electrical kW.
The energetic requalification will allow the optimization of thermal consumption and to produce, thanks to the co-generator, an estimated amount of electrical energy of about 42.500 kWe / year. Considering the electrical consumption of the heat pumps for the heating, in order to close the energetic cycle, it is necessary to install a photovoltaic system (the project is currently being studied given the fact that The Chiesa del Carmine is situated in the historical city centre and is subject to monumental and heritage restrictions).
This intervention would allow a drastic reduction of the current polluting emissions, which are equal to 65.94 T of CO2 / year. The electrical production of the co-generator occurs with the use of methane gas: a bivalent technology capable of producing both thermal and electrical energy using only a minimum amount of methane.
