Low temperature district heating is recognized as a key technology for the (cost-) efficient integration of renewable energy and waste heat sources in our systems. Several studies indicate that deployment local schemes measure reaching politically set climate goals. Further, implementation low systems are recommended taking maximum advantages synergies with other sectors decarbonization sector. Within IEA DHC Annex TS2 project already realized community system concepts well planned or designed identified visualized. Furthermore, projects showing an innovative use operation buildings also included analyses. The different assessed compared. presentation demonstrators up such way knowledge generated about indoor system, competitiveness systems, giving evidence these feasible, reliable under various boundary conditions. further there existing challenges, where research on integrating decentral feed-in required. analysed regard to which elements new they can generate. For each demonstrator specific innovations focus. case show related business models utilities change when temperatures lowered. paper presents discusses results from current work within Implementation Temperature District Heating Systems (Averfalk et al., 2021; TS2, 2021 [1]).
