Heat pump concepts for near zero-energy buildings
1) Optimisation of concepts for buildings in order to reach Nearly Zero Energy consumption applying heat pumps as core component of the building technology
2) Evaluation of building- and system integration options favorable for the application in Nearly Zero Energy Buildings
3) Requirements for further developments of current marketable heat pumps to exploit specific performance opportunities in Nearly Zero Energy Buildings (e.g. multi-source ability, capacity range, capacity control, temperature lift)
