Open data-based planning tools for cross-sector municipal energy supply using open, integrated ICT ecosystems


In the context of the energy transition, the close interconnection of various energy sectors is becoming increasingly important. The exchange of energy between different sectors - such as electricity, mobility, and heat - offers many new opportunities for the sustainable, carbon-neutral transformation of the energy system. Renewable electricity, for example, could supply those sectors that currently primarily rely on fossil fuels, particularly district heating through heat pumps. There are many successful examples of this, which are now being adapted locally and applied as intelligent, holistic district concepts on a widespread scale.

However, the interconnection of sectors creates a complex system with numerous strong interactions. The project "ODH@Jülich" is developing an open planning and simulation tool for this system, integrating all sectors and accessible to all users. It lays the foundation for comprehensive, cross-sectoral energy supply in urban districts and their (partial) automated planning and operation processes. It facilitates investment decisions for supply systems that are intended to serve for decades.


The project »ODH@Jülich« (Open District Hub @ Jülich) is developing scientifically sound, data-based methods for the development of a digital planning and simulation tool for energy supply in neighborhoods. »ODH@Jülich« combines examples, concepts, methods, and data on one hand, and develops tools for planners and architects on the other hand, enabling them to incorporate the accumulated knowledge into customized solutions for local projects quickly and easily. The project's results are designed to be open-source software to be available to a wide range of stakeholders, and can be integrated into the planning of many future neighborhoods. As a result, the project makes a valuable contribution to the energy transition.
