Welcome to the Project 61 of HPT TCP
Heat pumps in Positive Energy Districts
The Annex will investigate heat pumps concepts for positive energy districts regarding heat pump design and control as well as integration options from the individual building to district level. Concepts will be evaluated by both modelling/simulation and monitoring of heat pump performance in new built and existing districts.
