Dynamic heat map as a part of the regional energy transition

Heat maps show the heat and cold demand of residential, commercial and industrial buildings as well as the waste heat from industry. They combine these two aspects in order to plan new heating/cooling grids. By planning the thermal energy supply in a central way, the efficiency of the energy production and the overall exergy rate are also increased. The paper will present the methods of modern web-based heat mapping with a user oriented interface in the example of Saarland region, Germany. An overview of the heat demand survey including development of building and settlement typology by clustering as a base of the heat mapping will be given. In a forecast, further possibilities by a dynamic approach related to demography but also to response functions for users are elaborated.
