Cost-Effective augmented reality tool for enhanced building envelope panel handling: installation and validation

As part of a project aimed at upgrading older, non-renovated buildings by retrofitting their envelopes to meet the European climate targets required by 2050, a low-cost Augmented Reality (AR) tool was developed to facilitate the renovation and maintenance process. Considering that the renovation process involves a large number of different panels, which are assembled like a large puzzle in the building using plug-and-play techniques, traceability remains a challenge. To facilitate the assembly of the panels, which contain digital information, and using AR techniques, the panels will be displayed on the real building in their final position. In this way, AR tools will bridge the gap between digital information and the real-world environment, allowing users to visualise information about the position to be installed in the real place. Additionally, the tool will have the option to display further information (such as safety instructions or installation details) related to each panel, ensuring that workers have all necessary information on-site. Developed as a web-based Single Page Application (SPA) compatible with standard smartphones and tablets via WebXR, the tool eliminates the need for expensive hardware or software installations. The tool demonstrates the feasibility of using a cost-effective AR solution to provide necessary information to on-site operators, as well as generating real-time Key Performance Indicators (KPIs) and alerts that managers can consult.
