1. What are the major challenges, restraints, and supply-chain risks for the Digital Twin For Buildings Market?
Legacy building management system interoperability, data governance, and specialist talent shortages are the major restraints. Supply-chain risk is concentrated in IoT sensors, edge gateways, and semiconductor components; typical integration windows at large portfolios have been extended by 6–12 weeks when device inventory is delayed. In the 2025 global survey underlying this report, 54% of facility managers identified legacy BACnet data quality as the main deployment bottleneck.
