摘要：We propose and describe a method for the estimation of the energetic rehabilitation state of buildings. It combines a virtual 3D citymodel with real measured heating energy data in order to determine energetic relevant building characteristics. Among thesecharacteristics are, e.g., the volume, the assignable area, the building type or the surface-to-volume ratio (S/V). Using these valuesthe energy consumption characteristic, which is normally given in kWh/m2, can be calculated. This allows to classify a building intopredefined heating classes. Additionally, an estimation of the energy consumption of buildings is calculated on the basis of buildingtypologies and is compared to the real consumption values. Using these results, estimations of the energetic rehabilitation arederived.
