The Happening system has been running continuously since autumn 2020, providing heat in the heating season and domestic hot water to the utilities.

The Italian pilot project is located in Verzuolo in the region of Piedmont. The building contains ten homes in a climate with hugehog temperature differences between winter and summer.

Climatic zone (Köppen): Climatic zone (Köppen): Dfb (Warm-summer humid continental climate) ​

Weather characteristics: ​

  • Colder winters (average T in January: 0,3 ºC). ​
  • The warmest summers among the three locations, in which cooling needs may be important. ​
  • High temperature difference between winter and summer months. 

Building description

It has been renovated in the last fifteen years, with interventions on building envelope. The insulation level corresponds to 2006 regulations. It is a two-floor building (5 dwellings in each floor). The dwellings are 2 room apartments, from 32 to 42 m2​

Ownership: The ownership is private (single owner), while inhabitants are tenants.

Existing heating and DHW System: A centralized gas boiler supplies hot water for space heating and DHW of all the apartments. In the rooms, the heat emitters are fan-coils. 

Existing control and monitoring System: A control and monitoring system currently exist on the building. In each dwelling, ambient temperatures are measured and act on fan coils operation. An old thermal and electricity consumption meters is present, but currently decommissioned. It allows also to remotely visualize and control the heating system main parameters. A new BMS and measurement system will be implemented. ​

Building energy consumption

Space heating and DHW ≈ 50 MWh​

Electricity consumption ≈ 18 MWh 

This pilot is now fully operational and collecting data

The pilot project developed in Verzuolo has now been fully operational since November 2022. This signifies a significant milestone towards demonstrating the viability and efficiency of integrating heat pump technology with photovoltaic systems in residential settings.

The HAPPENING EU project continues to pave the way for more sustainable energy solutions. It shows that integrating advanced heat pump technology with renewable energy sources is feasible and beneficial. This pilot project is a model for future installations, showcasing the potential for significant energy savings and reduced environmental impact.

Installation process
The installation works were completed in a structured and timely manner. “It took one month to set up the photovoltaic installation, which included mounting PV panels on the roof and installing inverters, storage, and safety devices in the technical room. The hydraulic system installation took an additional two months”, explains Lorenzo Civalleri, pilot project coordinator member of HAPPENING partner Tecnozenith.
 
Preliminary results

Civalleri emphasizes as well the expected efficiency benefits. “Energy savings are challenging to assess now, as cooling is newly introduced, PV panels contribute to energy supply, and part of the building still uses the old system”.
