This comprises one subsystem that produces thermal energy (heat, cold, domestic hot water) based on geothermal heat pumps and hybrid photovoltaic solar collectors. And another one, based on PV panels, which will fully cover the thermal subsystem power consumption and will use storage battery array equipped with an intelligent energy management system that will assure the functioning of demosite in off-line mode for a certain period. The borehole heat exchanger of the heat pumps could be used for passive cooling of the building during the summer while the active cooling of the heat pumps can supplement the cooling demand.
The thermal energy and electricity produced from RES will be mainly used to feed a Target Building. Overproduction of both heat and power will be injected in the university DH network and local power grid.
The installations on site are about to start – heat pumps, PVTs, PV panels, inverters, converters, SCADA servers and fan coils units are being unpacked and waiting to be installed.
