Abstract

Although CityGML geometrical data exported either from GIS data or from compatible design software are suitable for scene rendering and navigation, they are not directly usable for energy simulation purposes because the second-level space boundary information, essentially surface pairs through which thermal energy exchange among buildings or building rooms or among a building room and its outside environment occurs, is missing. In order to address this need, a district space boundary topology generation algorithm, that takes as input data formatted according to the CityGML standard, is introduced. The algorithm is based on four main processes and special operations which are designed according to specific input data scenarios. The algorithm is demonstrated with successful results on examples with Level Of Detail 2, 3 and 4, as defined in the CityGML standard. Also certain cases requiring further investigation are discussed
