Plan heat networks.
Simulate buildings.
In one tool family.
Built on 20 years of research at TU Dresden. For engineering offices, utilities and energy providers — computed locally, no cloud lock-in.
One year, computed hour by hour
A static design gives a single peak value – usually heavily oversized. VICUS computes every time step and reveals the real load profile across the whole year.

What Our Customers Say
With VICUS Districts we were able to precisely determine the heat gains of our low-temperature network — and prove that the project is economically viable compared to insulated networks.
The steady-state analysis capabilities and the detailed ground model are unique. We haven't found anything comparable in any other software.
Digitizing existing pipe systems is one of the biggest challenges for utilities. VICUS Districts is a supertool for that!
Digital twins and simulations are essential for efficient heating networks. VICUS Districts opens up entirely new perspectives for us and network operators.
