From low energy to nearly zero energy – heat pumps for high performance buildings in HPP Annex 32 and 40


High-performance buildings are a key strategy for climate protection targets. The HPP Annex 32, concluded in
2011, stressed the suitability of multifunctional heat pumps for application in low-energy buildings. The new
HPP Annex 40 catches up with the political targets of Nearly Zero Energy Buildings (NZEB), which will set
the standard for new buildings from 2020 on. Annex 40 has just started, and is to develop heat pump technology
and system concepts for the requirements of NZEB.
