Great importance is assigned to heat maps as integral planning tools in the transition at local level to renewable heat sources. In addition to their methodological weaknesses (fixed and parameter-based calculation approaches and accuracy and topicality of the chosen base data), existing heat maps are unable to be adjusted, updated, maintained or respond to individual planning issues. This means that reports, maps and spatial data sets generated in the course of assessing the heat demand become quickly outdated and so, in practice, have no relevance for specialist planning. In order to create a meaningful and useable basis for future regional planning processes, the different planning steps must be dynamically presented, while also taking changing framework conditions into account (such as demography, climate change, quality of built volumes, etc.), and be communicated across sectors for a highly diverse range of municipal planning purposes. Furthermore, it needs to be possible for later users to maintain, adapt and update the developed system and to use it for individual matters.
The aim of the project is to conceptually design an updatable, GIS-based planning tool, which allows a clear presentation of the current heat supply situation and the future development of individual residential areas. Consequently, the dynamic heat map shall provide a basis for the decision-making concerning energy-related measures in urban, transport and infrastructure planning within the context of the transition to heat from renewable sources. In doing so, the obstacles to working together with different groups involved in the planning process shall be removed and it shall be made easier to exchange expertise with one another.
The focus of the project lies in the following two questions:
(1) What requirements should fulfil a modern heat-planning tool from the view of the users?
(2) How can these requirements be technically implemented?
By finding answers to these two questions, an important contribution shall be made to improve the quality and applicability/practicality of heat maps in the future.
- Benchmarking of marketable heat maps
- Concept development by conversational mode
- Design phase (technical)
- Implementation for test purposes
