District heating plays an important role in facilitating a transition towards cleaner energy in Denmark. In today’s digital district heating technologies, data validation and reconstruction are either missing or done to a limited extent. This has to change to unleash the full potential of digitalization. Currently, district heating distribution companies take a reactive “wait till it breaks” approach to maintenance which is accompanied by non-efficient planned maintenance. There is an urgent need for smarter and proactive maintenance strategies.

Worldwide buildings consume about 40 percent of the overall energy resources and contribute to an average of 30 percent of the global carbon emission. Hence, technologies for improving the energy efficiency of buildings play an important role in the global fight against climate change.
