Swiss step model

There is a great need for renovation in Switzerland's building stock. The renovation rate is clearly too low in the context of the energy transition and the energy crisis. Every second apartment built before 1980 is in need of renovation from an energy perspective. Landlords in Switzerland have too few incentives to carry out renovation work on the buildings they rent out in order to achieve more efficient use of fossil fuels. Effective instruments for achieving the Swiss energy targets for 2050 are lacking and incentives for investments in energy efficiency are inadequate or at least in need of improvement. The potential for improvement in the area of building energy efficiency is particularly high in Switzerland.

In Germany, such an incentive system will be introduced from 2023 using a so-called tiered model. The tiered model regulates the distribution of the cost of the CO2 tax between tenants and landlords. The more energy-inefficient the rented residential property is, the higher the share to be borne by the landlords.

​

The concrete political and legal feasibility of a tiered model in the Swiss context is currently being analyzed.
