Real-time insight, continuous optimisation, and whole-life performance management.
What is it?
A Digital Twin is a live, virtual replica of a physical building – continuously updated with real-time data from sensors, systems, and user input. It connects the design, construction, and operational phases into a single, intelligent feedback loop.
In the context of building performance, a Digital Twin typically integrates:
- Dynamic simulation models (e.g., from TM54, DSM tools)
- Sensor data (temperature, occupancy, lighting, CO₂, etc.)
- BMS and IoT systems
- Operational performance KPIs (e.g., energy use, thermal comfort, IEQ)
- Predictive analytics and scenario testing
The result is a powerful tool that allows you to monitor, compare, optimise, and forecast building behaviour – in real time and over its lifecycle.
Why is it important?
Closes the Design–Performance Loop
Digital Twins align design expectations with real-world outcomes by:
- Comparing predicted vs actual energy use (e.g., TM54 outputs vs metered data)
- Identifying underperforming systems or unexpected behaviours
- Supporting Building Performance Evaluation (BPE) and fine-tuning
Informs Smart Decision-Making
By visualising and analysing real-time data, Digital Twins help building operators and asset managers:
- Optimise comfort, energy, and maintenance
- Simulate “what if” scenarios (e.g., changing occupancy patterns, climate stress testing)
- Improve FM efficiency through predictive maintenance and fault detection
Supports Net Zero, NABERS, and ESG Goals
A Digital Twin provides the data and tools needed for:
- Demonstrating actual performance to stakeholders
- Tracking performance against Net Zero and ESG targets
- Supporting frameworks like NABERS UK, RIBA 2030, LETI, and GLA performance-based routes
In Summary
Digital Twins offer a new paradigm in building performance – shifting from reactive maintenance to proactive, data-led optimisation. They help ensure that sustainability goals aren’t just designed on paper, but delivered in practice.
Need support developing a Digital Twin Strategy for your building?
We work with developers, design teams, and asset managers to integrate digital twin thinking – from early-stage modelling to live system integration. Whether your goal is energy optimisation, certification, or Net Zero alignment, we can help bridge the gap between model and reality.
