CO2-neutrale Gebäude bis spätestens 2045

Ein Diskussionsbeitrag für eine ambitionierte und sozialverträgliche Politikstrategie

  • Publications 02.11.2021

A new Zukunftsimpuls of the Wuppertal Institute shows which course politics must set to make the building stock climate-neutral by 2045. The paper focuses on higher efficiency requirements for existing and new buildings, a faster phase-out of gas and oil heating, but at the same time higher incentives and better support for building owners as well as renovations that do not affect rental expenses in order to protect tenants from being overcharged.

Existing buildings must be renovated in such a way that they consume hardly any energy, similar to new buildings. At the same time, heating energy and electricity supply must be completely converted to renewable energies. In addition, the increase in building space must be slowed down through more intelligent utilisation concepts. Thus, the coming legislative period is crucial for achieving climate-neutrality in the building sector by 2045 at the latest.

This Zukunftsimpuls proposes a consistent policy package comprising 14 measures. In addition to the above this includes clear targets for better energy refurbishment and for the phase-out of fossil gas and oil heating. Individual renovation roadmaps for all buildings to be efficient by 2028 at the latest and municipal heating plans help building owners with the technical development of their buildings and investment planning. It is often the non-monetary barriers that are decisive for the low rate of renovation. One-stop-shops reduce the barriers which prevent implementing measures. Furthermore, neighbourhood management has a supporting effect and helps combining forces.
