Renovation Digital Twin for Building Retrofit Monitoring: A Software Product and An Organizational Ecosystem

Abstract: Digital twins are one of the most promising technologies as they provide real-time data and use simulation to inform and help speed up decision-making processes. This paper presents the design, development, and deployment of a Renovation Digital Twin (RDT) that enables monitoring of the retrofitting progress and the provision of feedback to the project stakeholders. The RDT platform aims at addressing a set of 7 design requirements including compliance with the General Data Protection Regulation (GDPR) while sensing building data. The RDT developed integrates 13 Key Performance Indicators (KPIs) allocated to 5 application domains: quality, cost, scheduling, safety, and environment.
