**OFIS' SOLUTION -** OFIS defined a pragmatic approach to combining occupant well-being with energy savings:

- Onsite heating system readings, while identifying standard building and accommodation characteristics (insulation, ventilation, etc.);
- A hydraulic heating network simulation, including heat loss and flow calculations to be applied to the network;
- Network distribution diagrams with adjustment devices indicated;
- Onsite adjusting of balancing components, located at the base of the column;
- A complete report when the work is finished.
