Methodology for GIS-based heat demand analysis in large urban areas

摘要

In this study GIS-based (GIS - geographic information system) analysis are described, which consider the location heat demand (households, commercial, industry etc.). Based on a database with more than 20 million data sets a wide variety of heat analyses can be done. The evaluation of individual heat consumers and the generation of heat maps show areas with a high or low heat demand. Other factors give information about ways to set up a central heating plant and the development of a heating network. Considering different scenarios allows on one side economic evaluation of heating networks and on the other hand a future forecast of the heat demand can be done. All results help to perform cost-effective project planning and to identify economically viable locations.
