Process of converting laser scans into BIM models for energy simulation purposes

Abstract

This study aims to develop a systematized workflow for converting laser scans, captured with mobile devices equipped with a LiDAR (Light Detection and Ranging) sensor, into BIM models compatible with energy simulations in Autodesk Revit. The methodology employs the pCon-Scan application to generate three-dimensional models, which are subsequently interpreted and converted into parametric geometries in Revit using Python scripts developed within Dynamo. The process was developed through iterative testing, initially applied to isolated environments and later extended to an entire building. The results indicated greater accuracy and consistency in single-environment models, while simultaneous scans of multiple spaces revealed certain geometric limitations. Nevertheless, the workflow demonstrated strong potential for automation, reducing manual steps and ensuring direct compatibility with Revit’s “Systems Analysis” tool. The process is currently in a refinement phase, seeking optimizations that enhance its efficiency, accessibility, and integration for the energy labeling of existing buildings.
