Knowledge about heritage buildings and structures is interesting for a wide variety of stakeholders,
ranging from architects to operators or the public administration. Such knowledge includes a large
variety of physical and functional characteristics of the building. Laser scanning allows efficient and
accurate 3D digitalization of heritage sites and subsequent data processing towards the creation of
geometrically and semantically rich models.
Parameterization and semantic enrichment of heritage building representations towards the creation
of Heritage Building Information Models (HBIM) generally involves the use of point clouds
and images as templates for manual mapping procedures in commercial software. Indeed, the information
to include in BIM models depends on the requirements of the application it is intended to
serve. In view of that, the applications presented in this chapter pertain to automated techniques
that were implemented to parameterize point clouds towards models suitable for energy analysis
The challenge in automating the reconstruction of heritage buildings is to deal with their geometrical
complexity and irregularity, meaning that the methodologies selected should be robust and
efficient under these conditions. The resulting 3D semantically rich model enhances the knowledge
of the heritage building, complementing other representations of the facility such as point clouds or
handmade HBIM. The procedure is implemented and validated in a real case study: the Ducal Palace
in Guimarães (Portugal).
