The building sector is one of the key consumers of energy in Europe today with an overall rising trend over the past 20 years.  In order to achieve the EU 20-20-20 goals or the targets set in the EU Energy Roadmap 2050, it is essential to renovate and retrofit these buildings and to replace inefficient heating systems based on fossil fuels or direct electric heating. The proposed heat pump technology offers a solution to both present and future challenges.

The goal of the GreenHP project is to investigate and develop a new highly efficient heating system based on high-capacity air/water heat pumps for retrofitting multi-family houses and commercial buildings with a focus on cities. This high power heat pump system will use an alternative refrigerant and will interact with large (renewable) energy systems, like the smart grid in particular, and will include other renewable energy sources, like photovoltaic and solar thermal, as well as energy storage.
