The project consists of extending the existing heating and cooling networks on the Erasmus campus and centralising production in a building called ‘PowerHouse’, in particular with a view to facilitating the integration of renewable energies. Its ambition is to support the development of the campus while optimising its environmental performance and limiting operating costs. 1) Heat network It is planned to renovate and extend the existing heat network to almost all buildings on campus. The heating network must be powered by a fully centralised fossil/renewable hybrid energy mix. 2) Refrigeration network It is planned to renovate and extend the existing refrigeration network to the main existing and future consumers. It is planned to centralise only the production of renewable cold in order to limit the size of the pipes to be installed and the amount of investment. The rest of the refrigeration production will therefore remain decentralised. The total length of the developed district heating and cooling lines is 2.10 km.
