When developing and refining this mix of instruments, it is crucial to find the right balance between an appropriate market-based framework, funding programmes, regulatory law and information activities. A balance between measures to increase energy efficiency and others to promote the use of renewable energy is important here. It is crucial to prevent lockin effects and also to take social aspects into account adequately. Training and continual professional Achieving the goal of making Germany's building stock virtually climate-neutral by 2050 relies on putting in a place an intelligent and balanced mix of instruments over the next years and decades, including research and innovation, providing information advice, and support and creating the regulatory framework needed to drive forward the introduction of sustainable buildings, focusing equally on existing and new buildings. There is already a broad range of regulatory provisions, funding programmes such as the CO, Building Rehabilitation Programme, the Market Incentive Programme Promoting Renewable Energies and many other existing or planned measures to provide funding for climate-friendly buildings. The economic feasibility of the measures and the need to ensure building and housing remain affordable must be taken into account. To ensure the costs arising from buildings having to comply with climate regulations do not prevent owners from refurbishing them, a programme of government incentives should be continued. consumption in buildings in 2030 must be gradually increased in order to meet the target of achieving a virtually climate-neutral building stock by 2050. Further milestones must be defined on the basis of the results achieved by 2020 and the measures needed to enable targets to be met must be put in place.
