Sector Coupling with Optimization: A comparison between single buildings and combined quarters

The combination of building technologies with renewable energies, storagesystems and low carbon technologies, like Combined Heat and Power (CHP) andheat pumps, demands to consider different energy networks, i.e. sector coupling,in their building energy management systems (BEMS). This and the observationthat energy equipment in buildings is often oversized and seldom used to its fullpotential during the most time of the year calls for a holistic approach toestablish sustainable multi-energy neighbourhoods. In this work, we introduce amodel for a district energy system with sector coupling that integrates BEMS andcompare the results of this model for the optimized operation of single buildingsand the integrated solution to quantify the possible saving potential.
