Will gas and oil be a thing of the past by 2024?

The past year was marked by inflation, rising interest rates, changes in the real estate market, and new regulations for builders and property owners alike. Now, 2024 is bringing its own unique challenges. Above all, property owners are concerned about the Building Energy Act (GEG), which has undergone a number of changes in recent months, some of which were predictable, others surprising.

What does the Building Energy Act 2024 say and what problems does it pose for property owners?

The GEG stipulates that heating systems (both in new buildings and existing properties in new development areas) must use a minimum of 65% renewable energy from January 1, 2024. The type of energy used depends on the local heating plan of the city. Anyone building a new home or located in a new development area should therefore take this requirement into account in their cost planning.

The GEG recently caused a stir when, in the final stages of last year, the Federal Constitutional Court ruled that the funds earmarked for subsidies and subsidies were unconstitutional. as a result, owners currently have no way of having the costs they will incur co-financed by the state.

The background to the decision is that during the coronavirus pandemic, the state made more funds available than were actually used. It was therefore decided to use the surplus funds to provide households affected by the GEG with an annual taxable income of up to €40,000 with a subsidy of up to €21,000 via the so-called Climate Transformation Fund. However, this was quickly deemed unconstitutional, and it is still unclear how the state intends to compensate for the promised and, in some cases, already allocated budgets.

Who is affected by the GEG 2024?

  • everyone who has to install a new heating system from January 1, 2024, provided that the building is located in a new development area (it does not have to be a new building for this regulation to apply)
  • New buildings outside a new development area can take advantage of a transition period until June 30, 2026 in large cities and until June 30, 2028 in smaller cities, but must still be retrofitted

Who is not affected by the GEG 2024:

  • existing and still fully functional heating systems that run on fossil fuels in existing buildings
  • heating systems in existing buildings that are fully repairable may continue to be repaired and do not necessarily have to be converted

I would like to continue operating an oil or gas heating system – what do I need to do?

Existing heating systems are initially unaffected by the GEG requirements and may continue to be operated or repaired. Under certain conditions, oil or gas heating systems may not only continue to be operated, but even newly installed. First, a mandatory consultation must be held to provide information about risingCO2 costs. If you still decide to install a new system, oil or gas heating systems are permitted as hybrid systems in combination with solar thermal systems, heat pumps, or by adding climate-neutral gases such as biomethane.

Who can install and use which heating systems in 2024?

Installation of heating systems in new buildings from 2024

  • Heat networks
    Heat networks are efficient systems that supply heat to several buildings. They usually use renewable energy sources such as biomass, geothermal energy, or waste heat. These networks can be particularly suitable for new buildings, as they enable a sustainable and efficient heat supply for larger building complexes and can be adapted to different needs thanks to their scalability.

  • Electric heat pumps
    These use ambient heat to heat buildings and are very efficient. They are attractive in new buildings because they can use renewable energy sources and are well suited for use in well-insulated buildings. Their main advantage is the reduction ofCO2 emissions.

  • Electric direct heating
    This type of heating converts electrical energy directly into heat. However, they are less recommended in the context of the GEG as they are often considered comparatively inefficient and expensive to operate and can have higherCO2 emissions.

  • Heat recovery through Bitcoin mining
    This method uses the waste heat from Bitcoin mining equipment to heat rooms. It is controversial because mining consumes a lot of energy and is not always used efficiently to generate heat. Under the GEG guidelines, this method is therefore probably less suitable.

  • Combined systems of renewable and conventional heating
    These offer flexibility by combining renewable energy sources with conventional heating systems. In new buildings, they can be a transitional solution to ensure efficiency and reliability while preparations are made for the switch to fully renewable energies.

  • Solar thermal
    Solar energy uses the sun to generate heat. Solar thermal energy can be effective in new buildings because it is a sustainable energy source and can be easily integrated into the overall concept for energy efficiency and sustainability.

  • H2-ready gas heating
    This type of gas heating is prepared for the later use of hydrogen. In new buildings, it could serve as a transitional solution, as it offers the option of switching to climate-friendly hydrogen at a later date, once its production and availability have improved.

  • Biomass heating
    Biomass heating systems use organic materials to generate heat. In new buildings, they can serve as a sustainable option as long as the biomass sources used are sustainably managed and the systems are modern and low-emission.

Modernization of heating systems in existing buildings

  • Log wood gasification boilers
    similar to wood gasification boilers, they use wood chips as fuel. They can be considered an alternative for existing buildings, but an assessment of their efficiency and environmental impact is crucial. New technologies may offer more efficient options.

  • Wood gasification boilers
    These boilers use wood as fuel and are an option for existing buildings to switch to a more sustainable heating method. However, efficiency and emission control are crucial to meet the requirements of the GEG.

  • Fireplace stoves
    These stoves are common in existing buildings, but are often less efficient and more polluting. Under the GEG, they could be considered as a replacement option, but modern, low-emission alternatives may make more sense in the long term.

  • Pellet and gas heating systems
    These heating systems can be a solution in existing buildings if they are powered by highly renewable gases or fuels – at least 65% of the gas should come from renewable sources such as biomethane, biogenic liquefied gas or hydrogen.

Sustainability in the real estate sector: support programs and benefits for owners

Sustainability is no longer just a buzzword, but plays a central role in the real estate sector. Owners who focus on energy-efficient construction, resource-saving modernization, or sustainable management of their properties today benefit in several ways: through government subsidy programs, long-term cost savings, and a significant increase in the value of their property. In the Olpe district and neighboring regions in particular, the requirements for sustainable standards are rising—and with them the demand for modern, future-proof properties. Whether KfW promotional loans for energy-efficient renovation, subsidies for photovoltaic systems, or special incentives from the federal states: it is worthwhile for owners to invest specifically in sustainable measures. In addition to reducing ongoing operating costs, such investments significantly increase the attractiveness of properties for buyers and tenants. Better rentability, higher return prospects, and a greater sense of security with regard to upcoming legal regulations are convincing arguments for more sustainability in real estate portfolios. Those who look into funding opportunities and sustainable concepts early on create real added value for themselves and future generations.

In Attendorn in particular, trends are emerging that offer long-lasting living comfort and flexibility in everyday life. Living spaces that create a feeling of freedom with well-thought-out lighting concepts, floor-to-ceiling windows, and spacious balconies are just as popular as practical features such as charging stations for electric vehicles, accessibility, and individual design options. such as charging facilities for electric vehicles, accessibility, and individual design options.

Barrier-free living: demand and implementation options in Olpe and the surrounding area

Barrier-free living is no longer a niche topic—demand is growing rapidly in Olpe and the surrounding region. More and more property owners and house hunters are recognizing the value of living space that is free of structural barriers and offers comfort for all generations. The focus is not only on seniors and people with physical limitations, but also on families who value flexible and future-proof living concepts. The growing demand for barrier-free real estate ensures that such properties are specifically sought after and carefully planned. Modern barrier-free apartments impress with wide passageways, level access, threshold-free bathrooms, and intelligent details that make everyday life noticeably easier. In Olpe, more and more builders, investors, and owners are focusing on high-quality fittings and innovative concepts in order to remain attractive in the long term and increase the value of their properties. Those who opt for barrier-free design early on not only secure a larger pool of interested buyers, but also invest in comfort and quality of life for the future. Especially in view of demographic change and new lifestyles, this is a decisive competitive advantage in the region's real estate market.

Real estate investment in 2025: opportunities and risks at a glance

The real estate market in 2025 offers both experienced investors and newcomers fascinating opportunities to diversify their investment strategies and enjoy sustainable returns. However, as in any area of investment, there are challenges that need to be overcome. In view of current economic developments and inflation, it is important to select the right properties with a clear focus and sound analysis. One key to success lies in close market observation and the identification of up-and-coming regions. Experts emphasize that interesting return opportunities exist particularly in urban areas with growing populations and increasing demand for residential and commercial space. However, potential risks, such as changing interest rate environments and regulatory uncertainties, should always be taken into account. Forward-looking planning and strategic alignment are therefore essential in order to fully exploit the advantages while avoiding potential pitfalls.

The role of the real estate agent in the modern real estate market: A guide

Current trends in the real estate market in 2025: What buyers and sellers should know

The real estate market in 2025 is facing dynamic changes that will have a significant impact on both buyers and sellers. One key trend is the increased use of digitalization in real estate, from virtual viewings to data-based price analyses. These technologies enable potential buyers to make informed decisions and offer sellers forward-looking marketing strategies. Demand for environmentally friendly and energy-efficient properties is also growing rapidly. Modern buyers value low emissions and sustainable construction, which has a significant impact on property values. Another trend is the urbanization of smaller cities, as more and more people are moving from large cities to smaller communities to benefit from a higher quality of life and lower prices. This development opens up opportunities for sellers who invest early in up-and-coming regions. At the same time, this means that buyers should consider more options outside the traditional "hotspots" in major cities. In summary, knowledge of these trends and their implications for the buying and selling process can have a decisive impact. It is now more important than ever for buyers and sellers to closely monitor the market and position themselves accordingly.
