In Germany, the building sector accounts for around 30 percent of energy consumption and CO2 emissions. A large proportion of the approximately 15 million detached and semi-detached houses are outdated in terms of energy efficiency. However, modern insulation and efficient heating systems based on renewable energies can significantly reduce energy consumption and increase living comfort at the same time. Refurbishment actively contributes to climate protection by reducing heat loss and lowering energy requirements. Deutsche Umwelthilfe points this out.
Despite the potential offered by an energy-efficient renovation, many homeowners shy away from the initial investment. However, long-term savings can offset the costs and also make a contribution to the energy transition. The economic benefits of renovations are evident: they can reduce CO2 emissions, cut the consumption of fossil fuels and make buildings less dependent on fluctuations in energy prices. In addition, modernized buildings ensure a pleasant indoor climate.
Various subsidy programs have been introduced in recent years to support owners in increasing energy efficiency. However, these measures are not yet sufficient to exploit the full potential. According to DUH, it is therefore crucial that politicians develop further solutions and improve the framework conditions to enable a sustainable reduction in energy consumption. This could also lead to economic and social benefits such as greater security of supply and the creation of new jobs.
