The EU-funded HAPPENING project is developing a solution based on decentralised heat pumps that are easy to install, low-intrusive for the building's occupants and easily adaptable to a large number of different building situations.

Currently, buildings are responsible for 40 % of the energy demand and 36% of the CO2 emissions in Europe. Decarbonisation of existing buildings plays a key role in order to reach the overall climate protection targets. However, current renovation rates lie in the order of 1%.
Heat pumps are a key technology in bringing renewable shares into heat supply of buildings; especially their combination with onsite renewable electricity production e.g. by PV allows to bring high renewable shares. Their current installation in existing multi-apartment buildings is however still marginal.
The proposed technological solution is based on decentralized heat pumps, in such a way that it results an easy-to-install solution for installers, low-intrusive for the occupants and easily adaptable to a large number of different building situations.
Through 3 demo sites (Spain, Italy and Austria), the project will demonstrate a highly versatile, scalable and replicable solution package for buildings energy system retrofitting allowing 70-75% of renewable energy fraction, 30-50% of PE and GHG savings, reduction of planning time by 50% and installation/operation time by 30% and payback time for ESCOs and investors of less than 8 years, compared to best available solution existing today.
Start date: October 2020 - End date: April 2024
