The consumption of heating energy in existing buildings represents a large share of total national energy consumption and therefore contributes significantly to the production of climate-damaging CO2. In order to stop climate change and make a substantial contribution to climate protection, heating energy consumption must therefore be reduced urgently. The most effective way to do this is to maintain and renovate uninsulated buildings. Thermal insulation is and remains one of the most important measures for reducing energy demand in buildings. Interior insulation has become increasingly important in recent years. This is due to the fact that a considerable part of the building stock, which can easily be insulated from the outside, has already been renovated. On the other hand, the proportion of remaining buildings where, for various reasons, only interior insulation is possible or even more advantageous, is becoming larger and larger. The surface area of the exterior walls accounts for a large proportion of the total building and thus of the potential for energy optimisation. In order to achieve optimal renovation success, the presented concept is developed on the basis of the existing condition of the building.:1 Introduction 1
