The energy-efficient renovation of real estate is usually associated with high costs. Since the available capital is often not sufficient for a complete renovation, the sequence of measures to be carried out should be systematic.
Homeowners should seek advice
When carrying out an energy renovation, it is important to carry out the measures in a specific order in order to achieve optimal results. First, professional energy advice should be sought to assess the energy condition of the building and recommend suitable measures. It is important to note that the exact sequence of actions depends on various factors, such as the condition of the building, individual goals and the available budget. Professional energy advice can help to determine the optimal measures and their sequence for a specific building.
Tips from the neighborhood can also be helpful, as homeowners who have already completed energy-saving renovations can point to special features, experiences and contacts to nearby tradesmen.
Minimize heat loss
According to Merkur, one of the most important measures is the insulation of the building envelope. The roof insulation should be done first, followed by the external wall insulation and finally the basement ceiling insulation. Effective insulation reduces heat loss and improves the energy efficiency of the building.
After insulating the building shell, you can consider replacing old, leaky windows and doors with energy-efficient models. This helps to further minimize heat loss and increase living comfort. It is advisable to carry out this measure after insulation so as not to impair the effect of the insulation.
Efficiency of the heating system
Another important step is optimizing the heating and hot water system. An efficient heating system combined with an optimized hot water system can significantly reduce energy consumption. It may make sense to replace old boilers with modern condensing technology, heat pumps or other renewable energy systems.
Controlling the indoor climate and effective ventilation are also very important. According to a ZDF report, installing a controlled ventilation system with heat recovery can ensure a healthy indoor climate and minimize energy loss through manual ventilation.
Consider renewable energy
Finally, the use of renewable energy can be considered. If the building envelope is well insulated and an efficient heating and ventilation system is in place, photovoltaics or solar thermal energy can be used to further reduce the building’s energy requirements.
