Abstract: In this paper, we present a methodology based on 3D city modelling to manage a realistic energy analysis of the building stock, building per building, at a very large scale (national application for instance). This methodology is tested on the City of Ludwigsburg and its more than 14.000 buildings. The influences of the data availability and quality on the model accuracy are analysed, for both geometrical and semantical information data. This paper is concluded by exposing some technological trends and policy needs to improve the accuracy and potentials of this methodology.
