Due to the urban and central location and the high performance requirements, the possible alternatives for the most CO₂-free heat generation is severely restricted. In the two 200-year-old government and Grand Council buildings, the technical service life of some of the systems has been exceeded and the need for possible air conditioning of the rooms and halls is increasing. Together with the cantonal library, the Kunsthaus has the highest requirements in terms of room conditioning. The defined room humidity and temperature must be ensured all year round so that the more than 21,000 works in Switzerland's most comprehensive public collection are not damaged.

In the early phase of the preliminary study, possible access routes for district heating and cooling were sought together with the local energy supplier. Alternative options for the simultaneous generation of heating and cooling were investigated, the technical and structural feasibility clarified and then compared in economic terms.
In addition to recording the entire building technology, the status analysis also included feedback from technical operations and directly identified possible suggestions for improvement. Humidifying the supply air in the Kunsthaus is one of the biggest challenges. The energy-intensive steam humidification can only be replaced to a limited extent due to the existing lengths of the ventilation systems. For this reason, a possible central high-pressure pre-humidification system was proposed.
With the status analysis and the measures defined therein, as well as the feasibility study on renewable heat generation, the client has all the necessary information for further action and implementation planning.
