Building energy systems are usually tuned to run as efficiently as possible, which works well until a heatwave arrives, sensors drift out of calibration or equipment quietly degrades.
A new study argues the goal should be stability rather than efficiency, and sets out a digital twin that notices when a building is slipping outside its safe operating range and repairs its own control logic before occupants feel it.
Key benefits:
- The framework shifts the objective from optimisation to stability preservation, holding a building inside a defined safe operating envelope instead of chasing peak performance
- It combines physics-based modelling, live data assimilation and structural adaptation, so the twin acts on the system rather than only reporting faults
- Under combined disturbances, time outside the comfort band fell from 11.2% to 4.6%, drift accumulation dropped by 56.2% and average recovery after a fault shortened from 11.8 hours to 4.5 hours
