Scan-to-BIM Sistematizado: proposta de processo utilizando sensor LiDAR em dispositivos móveis para simulação de eficiênciaeEnergética

Abstract

This work presents the development and evaluation of an automated method for surveying and modeling existing buildings using LiDAR (Light Detection and Ranging) technology available in mobile devices, integrated with the BIM (Building Information Modeling) platform through Dynamo, a visual programming tool associated with Autodesk Revit. The proposal arises from the need to optimize the generation of digital models aimed at energy efficiency labeling by simulation, using the System Analysis feature of Autodesk Revit. The proposed process employs the pCon.scan application to capture room geometry and generate structured files (.eox), which are interpreted by a Python script embedded in Dynamo, automating the creation of indoor environments. The methodological approach is based on Design Science Research (DSR), which seeks to solve practical problems through the creation of artifacts — in this case, an automated workflow for surveying and modeling. The results demonstrate that the method is significantly faster than conventional surveying. The method proves promising for applications requiring speed in preliminary surveys, such as renovations, building regularization, or energy analysis, provided that highly detailed information is not required. Although it presents limitations, the time savings and direct integration with energy simulation processes highlight its potential to transform the field of existing building modeling.
