HAPPENING – HeAt PumPs in existing multi-family buildings for achieving union’s ENergy and envIroNmental Goals

The potential of heat pumps plays a key role in the decarbonisation of the building stock. However, existing buildings are still predominantly supplied with heat from fossil fuels and the energy from heat pumps is underutilised.
There is now a wide range of system solutions for existing buildings, especially for apartment blocks, which have different structural and energy requirements. This means that different heat sources and heat generators can be integrated and various hydraulic and spatial integrations can be realised.
In order for heat pumps to be increasingly established in existing buildings, systematic solutions are required for the processes of planning, implementation, operation and system operation.
The "HeAt PumPs in existing multi-family buildings for achieving union's ENergy and envIroNmental Goals" project, or "HAPPENING" project for short, aims to promote the installation of heat pumps in existing multi-family buildings in combination with clean electricity generation. This is because buildings are still responsible for 40 per cent of energy requirements and 36 per cent of CO2 emissions in Europe. Heat pumps are the perfect technology for integrating renewable electricity into heat generation in buildings with the help of photovoltaic modules. Especially in combination with on-site renewable electricity generation, e.g. through PV, high renewable shares can be achieved.
In the HAPPENING research project, the focus of product, system and process development is on centralised-decentralised solutions. System solutions are being investigated that combine a centralised heat pump or heat pump group with decentralised heat pumps.
Several variants are being considered as decentralised heat pumps: residential booster heat pumps (water/water) for space heating and/or domestic hot water heating and room-by-room booster heat pumps (water/air) for space heating and cooling.
At three locations, in Spain, Italy and Austria, the project demonstrates a versatile, scalable and replicable solution package for the energy-efficient refurbishment of buildings.
Fraunhofer ISE is leading the ‘Monitoring for performance evaluation and smart controls’ work package in the project and is supporting the project with its measurement data analyses.
