Applying graph theory to clean energy districts
Flow optimisation across heat networks

District heating networks provide heat to buildings through a network of underground pipes. Currently 80% of buildings in Switzerland still use oil and gas for heating, so we need new district networks to replace this with clean energy coming from renewable sources like heat pumps or waste heat from data centers.

Challenge
Optimising the layout and routing through this network is an interesting graph theory challenge. While Minimum Spanning Tree algorithms allow us to get the overall shortest network, in reality district heat networks carry hot water flows and we want to minimse the overall flow to reduce energy loss, while also being able to add new network nodes. In this challenge we will provide data for thermal networks represented as graphs, that participants can try different algorithms and solutions, and visualise the resulting heat flows.
