abstract = {Potential waste heat integration in low-temperature
district heating (LTDH) systems is a main task for future
sustainable heat supply. For evaluation of efficient LTDH
integration in residential areas, investigations of the
typical building stock are useful. In this study, we present
an economic and ecologic investigation of two LTDH supply
temperatures in multiple typical residential areas. We show
which design have the strongest impact on efficient heat
supply in terms of electricity usage and low specific
heating costs. Therefore, we design nine representative
residential areas derived from dwelling types of the German
building stock. Within these areas, we investigate LTDH
supply performance in combination with decentralized
boosting heat pumps. In addition, we compare the results to
an individual heat supply by air-water-heat pumps. The
results show that the fraction of domestic hot water on
total heat demand and the design of decentralized heat pump
systems capacities impact LTDH operation efficiency. LTDH
network installation with operation temperatures around 60
°C are most advantageous in residential areas with a high
share of space heating demand.},
