Join this week’s Gemini Call with Vignesh Ayyathurai, Uppsala University, to explore a practical digital twin workflow designed for existing buildings. In this session, Vignesh will show how sparse indoor sensing data, including CO₂ and temperature, can be combined with simulation and ensemble machine learning to infer ventilation performance and indoor comfort, creating a stronger evidence base for renovation planning.

This is a compelling session for anyone interested in making digital twins more practical, scalable and useful in the real world. Rather than relying on costly, sensor-heavy deployments, this approach demonstrates how minimal, low-cost sensing can still support meaningful building insight and help owners prioritise retrofit actions based on measured indoor environmental performance rather than assumption.

Why attend?

Many existing buildings need renovation, but decisions are often made without enough reliable operational evidence. This session will show how digital twin methods can help close that gap, offering a more accessible route to data-informed retrofit planning.

What you'll learn:

• How sparse sensing data can be used to support digital twin workflows in existing buildings
• How CO₂ and temperature data can help infer ventilation performance and indoor comfort
• How simulation and ensemble machine learning can strengthen evidence for renovation planning
• Why low-cost, practical approaches are essential for scaling digital twin adoption in the built environment
• How this workflow can support better retrofit prioritisation and decision-making

Who should attend?

This session is ideal for digital twin practitioners, building owners and operators, retrofit and renovation professionals, facilities managers, sustainability leads, researchers and anyone interested in practical approaches to improving building performance.
