      abstract     = {The substitution of fossil fuels in current energy systems
                      is essential on the path to carbon neutrality. In the
                      building sector, different renewable and waste heat sources
                      could be used in district heating systems to replace
                      fossil-based heating plants. However, if new heat sources
                      are integrated into multi-energy systems, the profitability
                      of present heating plants could decrease. At the
                      Forschungszentrum J¨ ulich, the waste heat from a new
                      high-performance computer is to be integrated into the local
                      district heating system in order to reduce overall CO2
                      emissions. This waste heat integration will have an impact
                      on the holistic multi-energy system of the campus, which is
                      mainly supplied by a combined cooling heat and power plant
                      (CCHP). This paper investigates the described waste heat
                      integration using a bi-objective optimisation approach. The
                      proposed model optimises the operation of the overall
                      multi-energy supply system with waste heat integration.
                      Furthermore, the optimisation model allows for the optimal
                      design of the required heat pump system and additional
                      absorption chiller capacity that enable efficient CCHP heat
                      usage despite the waste heat integration. In addition, the
                      effects of lowering district heating temperatures and
                      changed energy prices are studied. The results show that
                      integrating waste heat reduces the overall CO2 emissions of
                      the multi-energy system and even more if the integration is
                      combined with a lowering of district heating temperatures.
                      Furthermore, the optimisation shows that a cost reduction is
                      feasible by increasing the absorption chiller capacity that
                      uses the produced heat of the CCHP.},
