Toward a BIM-Centric Digital Twin for Sustainable Museum Operation: The MACA Living Lab Case Study

Abstract: Digital Twins (DTs) couple BIM and IoT for sustainable building operation, yet many implementations remain siloed, hard to scale, and difficult to interpret. This paper presents a stepwise DT prototype for an environmental-education facility, integrating indoor/outdoor sensing (CO₂, PM, temperature, humidity, occupancy) with a Revit BIM model. A Dynamo–Python pipeline maps cloud time-series to shared BIM parameters, enabling in-model visualization, threshold alerts, and KPI reporting. Initial deployment delivers the sensing-and-display setup and a reusable BIM data schema ready for automated synchronization. The lasting contribution is a replicable BIM-centric implementation method for room- and zone-level monitoring in sustainable cultural buildings.
