A Digital Twin Framework for Intelligent Indoor Environmental Monitoring and Adaptive Evaluation
This paper introduces a robust Digital Twin (DT) framework designed to optimize Indoor Environmental Quality (IEQ) by integrating static Building Information Models (BIM) with real-time IoT sensor data. The system dynamically assesses IEQ against national standards, prioritizing occupant comfort during occupancy and energy conservation during non-occupancy. This transparent and reproducible approach offers a pathway for enhancing well-being and energy sustainability in smart buildings.

7 Key Parameters
Temperature, humidity, PM2.5, HCHO, illuminance, noise, and occupancy are continuously monitored.
Adaptive Decision Support for Optimal Environments
The framework's intelligence lies in its ability to dynamically adjust operational priorities. This ensures occupant well-being during occupied periods and maximizes energy savings during unoccupied times, guided by national IEQ standards.
Case Study: University Office Implementation
In a real-world application, the DT framework was deployed in a university office. The system dynamically classifies the room as occupied or unoccupied based on HMD data and illuminance changes. This allows for adaptive control:
- During occupied periods, the system prioritizes occupant comfort and health, maintaining optimal temperature, humidity, and air quality levels.
- During unoccupied periods, the focus shifts to energy conservation and emission reduction, intelligently reducing HVAC load and lighting when not needed.
This adaptive strategy resulted in a balanced approach, demonstrating the DT's capability to deliver both human-centric comfort and environmental sustainability benefits.
