Energy-efficient building renovations lead to higher sales prices and rental income, providing an important incentive for property owners to invest. This is the key finding of a recent analysis by the Kiel Institute for the World Economy (Kiel Institute). Since 2022, apartments with an energy efficiency rating of A+/A command an average premium of approximately €650 per square meter compared to similar apartments with a D/E rating. For monthly rents, the premium is around €0.85 per square meter. However, this significant price advantage is primarily observed when the energy efficiency is certified through a Bedarfsausweis. In contrast, the premium is notably smaller when based on a Verbrauchsausweis.
