On the other hand, government support programs and grants offer attractive opportunities to reduce refurbishment costs. In the long term, you benefit from lower energy costs and improved quality of life. Our expertise in the real estate sector helps you make the most of these opportunities.
Energy-efficient refurbishment of older buildings is a complex topic that requires careful planning. It is essential to consider the building's individual circumstances and select the appropriate measures. Professional energy consultancy is indispensable in developing the best strategies for energy-efficient modernisation. Financing also plays a crucial role, as refurbishment costs can often be substantial. However, by leveraging support programs and choosing the right financing strategy, the financial burden can be significantly reduced.
Overview of Construction Interest Rates and Renovation Loans
The development of construction interest rates directly affects the cost of renovation loans. For 2025, a fluctuation and sideways movement between 3.0% and 3.5% is expected. Geopolitical events such as the US elections and the Ukraine war may further influence interest rates. It is therefore advisable to compare different providers like Dr. Klein, Interhyp and Baufi24 to secure the best conditions. Additionally, choosing between short and long interest rate commitment periods should be carefully considered. Special repayment rights offer additional flexibility in repaying the loan.
Government Support Programmes for Energy-Efficient Modernisation
The government supports the energy-efficient modernisation of old buildings with various support programmes and grants. The 'Young Buys Old' programme by KfW offers loans up to 150,000 Euros, but the future of this programme is uncertain. The continuation of the 'Home Ownership for Families' and 'Climate-Friendly New Building' programmes is also uncertain. BAFA supports individual renovation measures such as heating system replacements. In Hesse, there is the Hessen money for first-time buyers. It is important to inform yourself early about the various funding options and to submit applications in a timely manner. Find out about the latest changes in property purchases here.
Equity vs. Debt: The Optimal Financing Strategy
When financing an old building renovation, the question arises as to how much equity should be used. Currently, 85% of buyers use equity, averaging 22% of the purchase price. This serves to minimise the long-term debt burden. The annuity loan is the preferred financing instrument, with KfW loans making up a growing share (8% of financings). However, building savings contracts are rarely used (2%). A strategic financing plan should optimise equity use and consider the benefits of KfW loans. Our information on energy-efficient home buying can assist you with this.
The choice of the right financing strategy depends on various factors, such as the amount of equity, individual risk tolerance and interest rate prospects. Comprehensive advice from a financial expert is therefore essential to find the optimal solution. The use of government support programmes should also be included in the financing plan, as they can significantly reduce costs.
Building Envelope: Optimise Insulation of Facade, Roof and Basement
A common weakness of many older buildings is the building envelope. Effective insulation of the facade, roof and basement can significantly reduce energy consumption. For facade insulation, there are various methods available, such as the external thermal insulation composite system (ETICS) and internal insulation. When choosing the insulation method, the monument protection requirements must be taken into account. Roof insulation can be implemented as rafter or post-and-beam insulation. Insulating the top storey ceiling is also an effective measure. Basement insulation includes perimeter insulation and basement ceiling insulation.
Windows and Doors: Replacement with Energy-Efficient Models
Windows and doors also contribute significantly to heat loss. Replacing them with energy-efficient models featuring thermal insulation glazing can greatly reduce energy consumption. Pay attention to the U-value of the windows and take advantage of grants for window replacement. Frame materials available include plastic, wood, and aluminium. Tight seals are also important to minimise heat loss. Learn more about the advantages of an energy-saving house.
Heating System: Modernisation and Switch to Renewable Energies
Modernising the heating system is another crucial step towards energy-efficient modernisation of older buildings. Oil and gas heating systems should be replaced by modern, efficient heating systems.

Compliance with the GEG is not only legally required but also a prerequisite for accessing funding programmes. Professional energy consulting can help you meet the GEG requirements.
Heritage Conservation Requirements: Impact on Renovation Measures
When renovating listed buildings, heritage conservation requirements must be observed. Coordination with the heritage conservation authority is necessary, as many renovation measures require approval. The aim is to preserve the historical building fabric. Heritage conservation requirements can limit the choice of renovation measures and increase costs. Therefore, it is important to contact the heritage conservation authority at an early stage and coordinate the renovation measures.
