The "Digital Building Twin" as a Core Concept

Just as the "Digital Twin" revolutionized manufacturing, the concept of the “Digital Building Twin” is transforming facility management. A digital building twin is a virtual replica of an entire building complex, incorporating real-time data from the physical structure.

This is achieved through extensive data collection from various IoT sensors and devices, which continuously feed information into a centralized system. The integration of these data sources allows for detailed simulations and precise analysis of building usage.

Examples of data sources within a smart building:

• Heating and temperature control: Sensors linked to heating and ventilation systems collect real-time data and transmit it to a central platform. Based on this data, pre-configured automation algorithms adjust heating and ventilation dynamically to optimize indoor temperatures. Automated window controls can enhance air circulation to maintain optimal conditions.
• Lighting and illumination systems: Sensors monitor light levels and occupancy within different areas. What lighting temperature is most suitable at a given time? How does the external weather impact indoor lighting needs? These systems automatically adjust brightness and shading to match real-time conditions.
• Security technology: Fire detectors, video surveillance, air quality sensors, and other monitoring tools enhance security. Integrated with intelligent software, these systems link multiple data points to provide real-time evacuation lists, identifying who remains inside a building during emergencies. This interconnected security approach significantly improves safety levels.
• Access control and visitor management: Effective smart buildings access solutions are essential for security. Who is authorized to enter specific areas? Smart authentication and permission-based access ensure employees, clients, and visitors can only access designated zones for a predefined duration. Lost access credentials can be instantly deactivated to mitigate security risks.

This vast array of data sources provides businesses with valuable insights into how spaces are used, facilitating strategic planning for future utilization. By leveraging the digital building twin, facility managers can run virtual simulations and optimize space allocation for long-term efficiency.
