Digital Twins for Building Management: What, Why, and How
Cutting through the hype — what digital twins actually are, how they're used in practice, and whether your building needs one.
What is a digital twin?
A digital twin is a virtual replica of your physical building that stays synchronised with reality. Unlike a static BIM model, a digital twin is designed to be updated throughout the building’s lifecycle.
Beyond the marketing hype
Many vendors use “digital twin” loosely. A true digital twin should include:
- Accurate 3D geometry — Usually from laser scanning
- Asset data — Equipment specifications, maintenance records
- Operational data — Live or regularly updated performance metrics
- Integration capability — Ability to connect with BMS, IoT sensors, CAFM systems
Practical use cases
Facilities Management
Navigate the building virtually, access asset information in context, plan maintenance without site visits.
Retrofit Planning
Understand existing conditions, model intervention options, track performance improvements.
Space Management
Visualise occupancy patterns, plan reconfigurations, manage moves and changes.
Sustainability Reporting
Integrate energy data, track carbon metrics, demonstrate improvement over time.
Do you need a digital twin?
Consider a digital twin if you:
- Manage a complex building or portfolio
- Plan significant retrofit investment
- Need to demonstrate ESG performance
- Want to reduce reactive maintenance
How Kanna creates digital twins
