ABSTRACT

This chapter reviews the use of laser scanning for Building Information Modelling (BIM) reconstruction and describes a set of simple approaches towards the reconstruction of building façades for energy analysis purposes. It deals with the results obtained from applying the methodology to a particular case study the Paco dos Duques in Guimaraes (Portugal). Laser scanning allows efficient and accurate 3D digitalization of heritage sites and subsequent data processing towards the creation of geometrically and semantically rich models. Although laser scanners allow the accurate and efficient 3D digitalization of heritage, point clouds should be parameterized to create sets of components. 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.
