Analysis and location of demand side integration potentials in urban space using GIS based digital city maps

An Assessment of the Demand Side Integration Potential from HVAC for whole cities can be achieved through a detailed analysis of the building stock. Using GIS-based digital city maps in combination with usage-based characteristic data on the typical power installed in buildings for HVAC (such as the VDI 3807-4) an automated approach can be defined to achieve building specific data covering a whole city. This paper discusses a feasibility study for such an approach that was carried out at the University of Applied Sciences in collaboration with the Harbour City University both of Hamburg. Out of a total of about 340.000 buildings in Hamburg the study defined 832 buildings of office-like use with a noteworthy DSI potential from HVAC. The same method could be used to automatically analyse the DSI potential of other sectors of building use, the DSI for a whole city and/or be transferred to other cities with similar data bases. Because of the inherent connection to a GIS based data set the results can be easily displayed in maps. The paper gives an introduction into the method, shows some results achieved and discusses the approach and its transferability.
