In Germany, the greatest potential to save energy is offered by existing buildings: These use around three times more energy for heating than new buildings. In addition, around 87% of the total energy consumed in a private household is required for space heating and hot water. Up to 80% of this can be saved with a professional refurbishment and modern building services. The fact is, however, that only around a third of the energy savings potential is exploited on average in a refurbishment project.
