Simulation based multi-criteria evaluation of design scenarios for an industrial waste heat based micro district heating network supplying standard and low-energy buildings

This paper presents the results of a multi-criteria evaluation of different design scenarios for a micro-DH network in Vienna, Austria, which involves energy efficient buildings (supplied by heat-pumps and solar thermal panels) and a standard building (equipped with gas boilers). The aim is to assess the integration of industrial waste heat available on-site together with high and low-temperature storages, to balance the heat production and demand, and a heat-pump booster, to supply the network with the required temperature level. The integration of different temperature levels and different profiles from both the production side and consumption side constitute the main challenges.
