While facility managers are still focused on maintaining buildings in the most efficient ways possible, they have new challenges and priorities. In addition to implementing a digital transformation strategy and execution for improved sustainability, occupant comfort, productivity, and physical-logical security, they need to adopt post-quarantine protocols that prioritize indoor air quality, space utilization, people tracking, and contact tracing.

The world is swimming in data, but converting that into actionable information often remains more manual than automatic.
Industrial sites are multi-faceted – with physical properties and assets in varying conditions, networks of infrastructure and power flows to be optimised. Beyond assets and operations, facilities are affected by their environment as well as the organization and business itself.

Perception of cost to deploy and scale.
Applications of digital twins to Facility Management
Adoar Espania Slioa’s comprehensive Master’s Thesis at the School of Engineering in Jönköping, Sweden, identifies a facility management digital twin system as comprising three parts—BIM, IoT, and the digital twin. A flow of IoT data from physical sensors being analysed before flowing back to the physical asset as control feedback.
The paper outlines several benefits of digital twins applied to Facility Management. Each of the features below has at least one reference paper attached to it.6
Air quality
- CO2 level monitoring
- CFD simulations and measures CO2 level
Comfort
- Allows occupants to provide feedback for comfort
- Maintain comfort levels
- Monitors comfort levels
- What to monitor to improve comfort
Cost savings
- DT cleaning schedules save costs
- VAV Dampener control
- Decrease renovation costs
- Costs and scalability between sensors
- Digital twin cost vs benefit risk
- Post occupancy evaluation optimize implementation cost
Energy saving
- Predict weather, occupancy prediction control over VAV
- Aims to decrease net primary energy usage
Energy monitoring
- Decreases time for deep energy audits
- Monitors energy consumptions
Energy performance
- Monitor energy consumption
- Energy consumption and saving
- LEED criteria and energy monitoring
Error detection
- Detect errors through performance variations in components
- Detects building condition, rating the maintenance urgency
Experience feedback
- Collects from feedback
- Emotion detection software
- Indoor environmental quality
Occupant detection
- Detects occupants for spatial proximity
- What sensors are used
Occupant prediction
- Predicts occupants
Predictive maintenance
- Uses historical data to detect faults in Air handling units
Room experience
- Monitor luminance
- Monitors glare, daylight simulation
Thermal comfort
- Evaluate thermal comfort and proximity
- Thermal monitoring
- VR thermal comfort visualization
Even with significant technology advances, a digital twin project is still perceived to take significant resources and months to accomplish. This is one reason why so many projects get stuck at the proof of concept; the operational value may be clear but there’s no visible path to reducing the costs for each subsequent digital twin model deployment in utility operations.

BIM vs digital twins for Facility Management
BIM modelling was often touted as a route to better facility management. A computer model acted as a digital as-built model, replacing paper. However BIM was never designed to be a facility management tool.
Cloud-based digital twins offer many advantages:8
By transferring a BIM model into a cloud platform, all stakeholders can be integrated.
Better manage increasing complexity and incorporating new technologies, relevant to building operations but outside of the BIM scope.
Current status of an installation and its geospatial data available real time.
An integrated digital database for all stakeholders and cross-company networking along the entire building lifecycle.
A data-based tailor-made quotation for building-specific services.
Clear requirements that lead to targeted preparation and qualification of employees.
Remote analyses leading to increased process efficiency.
A comprehensive service history detailing all activities.8
BIM is a siloed tool, and never really created very well to be used by multiple parties or multiple data points. BIM is really a tool to get design and construction done better. Since a building changes every single day, facility managers need a tool to change with it.
— Jacob D’Albora, Director of Digital Building Operations, VIATechnik
By capturing and synchronizing data at a specified frequency and fidelity from various sources, you can visualize how your building has been performing, what is happening now, and what may happen in the future. You can use digital twins to break siloes in your projects. You can leverage it to convert your data to knowledge and support transforming the knowledge from one project to another.
