Bagnolo in Piano case
Large multifamily house finished in 1985 and has two staircases and four floors.
The building is a concrete structure, with brick cavity walls envelope, and hollow block floors and roof. The windows are single glass and wood frame.
The building is equipped with centralised gas boilers that provide energy for heating and domestic hot water (DHW). Air-Conditioning units provide cooling to some of the apartments.
The building will be deeply retrofitted with the whole HEART toolkit. Existing fuel-powered generators will be replaced with high-efficiency heat pumps. Each apartment will be equipped with three Smart fan-coils, connected to the heat pumps (DC-HP), in order to provide both heating and cooling. The electricity generated by Building-Integrated Photovoltaics (BIPV) is approximately 10 kWp will be mainly used to power the heat pump directly, using one multi-input multi-output unit (MIMO). In order to allow the storage of excess energy, thermal storage of about 4000 liters and a battery pack of 3 kWh, will be connected to the DC-HP. Windows refurbishment and opaque envelope insulation on the rest of the façades and roof will contribute to reducing the energy demand.
