Bottom-up heat demand mapping and techno- economic analysis of district heating expansion in data pour regions – case study for Velika Gorica, Croatia

Heat demand mapping is becoming an essential tool in the analysis of the feasibility of new and the expansion of existing district heating systems. This fact is emphasized even further as more and more advances are made in the utilization of excess and renewable heat sources making the knowledge regarding the spatial distribution of supply and demand even more vital. Analysis such as this are normally very data intensive and they often require information not available to researchers and industry or are available to cities and municipalities but in inadequate formats. The research conducted in this paper presents a novel approach to the use of open source and non-georeferenced information in data pour areas for heat demand mapping and techno-economic analysis of district heating expansion. The results have shown a consistent method for the bottom-up development of head demand distributions essential for such analysis. The city of Velika Gorica in Croatia has served as case study in this work.
