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

HAPPENING is a project which aims at enabling the efficient use of heat pumps in retrofitting of existing multifamily buildings. To do so, a cascade heat pump (HP) system is proposed, splitting the heat generation in two levels (combining central and individual HPs), which offers many benefits in terms of performance and adaptability.
