Location: Bagnolo in Piano, Reggio Emilia, Italy.
Building Description: Large multifamily house finished in 1985 and has two staircases and four floors.
Building Features: 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.
HVAC Facts: the building is equipped with centralized gas boilers which provide energy for heating and domestic hot water (DHW). Air-Conditioning units provide cooling to some of the apartments.
Retrofit package: The building will be deeply retrofitted with the whole HEART toolkit. Existing fuel-powered generators will be replaced with the 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.
