Abstract. The 3D BAG v. 2.0 dataset has been recently released: it is a country-wide containing all buildings in the Netherlands, modelled multiple LoDs (LoD1.2, LoD1.3 and LoD2.2). In particular, LoD2.2 allows differentiating between different thematic surfaces composing building envelope. This paper describes first steps to test use perform energy simulations characterise performance of stock...

IFC, buildingSMART open standard for Building Information Models, is underused with respect to its promising potential, since, according the experience of practitioners and researchers working BIM, issues in standard's implementation use prevent effective use. Nevertheless, a systematic investigation these has never been performed, there thus insufficient evidence tackling problems. The GeoBIM ...

An increasing number of applications rely on 3D geoinformation. In addition to 3D geometry, these applications particularly require complex semantic information. In the context of spatial data infrastructures the needed data are drawn from distributed sources and often are thematically and spatially fragmented. Straight forward joining of 3D objects would inevitably lead to geometrical inconsis...
