In view of rising energy prices and stricter climate targets, the energy-efficient refurbishment of properties is becoming increasingly important. But which measures are really worthwhile and how high is the savings potential? In this article, we take a detailed look at the benefits of energy-efficient renovations and provide practical tips for owners.
Why energy-efficient refurbishment is essentialEnergy-efficient refurbishment not only reduces energy consumption and heating costs, but also helps to maintain and increase the value of properties. In addition, many measures are subsidized by the state, meaning that the investment pays off in the long term. Particularly in older buildings, targeted renovations can achieve considerable savings.
The most important refurbishment measures at a glance
Insulating the building envelope - One of the most effective measures is to insulate the roof, façade and basement ceiling. Improved insulation considerably reduces heat loss, which leads to a significant reduction in heating costs.
Window replacement - Replacing old windows with modern, triple-glazed models prevents draughts and minimizes heat loss. This not only ensures greater comfort, but also a better energy balance.
Replacing the heating system - Switching to modern heating systems such as heat pumps or condensing boilers is one of the key measures for energy-efficient refurbishment. In combination with an optimized building envelope, heating costs can be reduced by up to 50 %.
Photovoltaics and solar thermal energy - The installation of solar systems to generate electricity and hot water offers a sustainable way to further reduce energy costs and become less dependent on external energy suppliers.
State subsidies and financing optionsThe state supports energy-efficient renovations with numerous subsidy programs. Owners can apply for low-interest loans and grants via the KfW Bank and the Federal Subsidy for Efficient Buildings (BEG). Depending on the measure, up to 50 % of the costs can be covered by subsidies.
ConclusionEnergetic renovations are a decisive factor for sustainable and cost-saving living. Owners benefit not only from lower energy costs, but also from increased living comfort and a higher property valuation. Government subsidies significantly reduce the financial outlay, making energy-efficient renovations worthwhile in most cases.
