Renewable student residence

The heating and cooling system is based on Thermia Mega L (14 – 59 kW), a new commercial ground-source heat pump with inverter-driven compressor. The main advantage of this heat pump is that it can continuously adjust heating or cooling output to current demand, which means that the heat pump can supply 100 per cent of the building’s energy requirements. In addition, the Thermia Mega can also provide simultaneous heating and cooling. If the primary function is cooling, any heat surplus is used to produce hot water. The system is able to swap between the hot and cold tanks without using energy from the boreholes.

The new energy solution has enabled the management of the Montegancedo student residence to offer extremely energy-efficient housing that is sustainable, renewable and guarantees superior comfort in its apartments. If the system’s energy and carbon values are compared to a conventional installation using a gas boiler, typical air-conditioning unit and solar panels, the energy saving and CO2 emissions for primary energy are 85,679 kWh/year (63%) and 20,777 kg CO2 emissions (56%).
