The aim of the IEA project is to develop economically attractive solar energy supply concepts with high solar fractions of at least 85% of the heat demand, 100% of the cooling demand and at least 60%
In a future world, where renewable energy is the primary energy soruce, it is important to understand the variability of the solar energy resource. Skilled forecasts of this will also be needed. This
This Annex focuses on the implementation of heat pumps in district heating and cooling networks. The purpose is to describe solutions and barriers for heat pumps. Flexibility in thermal networks and
