Danfoss Leanheat Building


Leanheat Building creates virtual storage in the district heating network by harnessing the thermal inertia of buildings: fewer peaks, more flexibility, the same comfort.

Business problem

In district heating systems, the daily demand profile has sudden peaks that complicate day-to-day operations and reduce overall efficiency.

Leanheat Building makes it possible to smooth out the load curve by tapping into the distributed flexibility of buildings’ thermal inertia, with no need for infrastructure investment.

Our solution

With Leanheat Building, every customer substation becomes an active node in the network. The platform aggregates the thermal behaviour of buildings and orchestrates it intelligently, turning building inertia into a flexible, controllable resource.

With Leanheat Building, you can:

  • turn customer substations into virtual storage;
  • reduce the peak of morning demand;
  • monitor customers to identify anomalies in real time.

How it works

By integrating field data, Leanheat Building uses advanced AI models to model the dynamics and behaviour of each building. In particular, the solution harnesses their thermal inertia to modulate substations and spread the load across the day, always ensuring user comfort.

  • Available exclusively as a cloud version (SaaS).
  • Average setup: 5–6 months.
