Engineering Contradiction Analysis
1Productivity
If building management systems integrate multiple data sources (as-built data, operational data, sensor data) into a unified entity-based digital twin model, then decision-making effectiveness and efficiency are improved, but device complexity and data integration difficulty increase
Solution Approach 1:
The building is divided into multiple entities (spaces, systems, equipment) with hierarchical relationships. Each entity is represented as an independent object in the digital twin model, allowing granular management and analysis. This segmentation enables the system to handle complex building data by breaking it down into manageable entity-level components that can be processed independently yet integrated through defined relationships.
Solution Approach 2:
The entity-based digital twin framework serves multiple functions simultaneously: it integrates as-built information, real-time operational data, and sensor data; provides visualization across 2D, 3D, and AR interfaces; enables predictive analytics and maintenance scheduling; and supports various building management tasks. This universal framework eliminates the need for separate systems for different management functions.
2Measurement precision
If real-time operational data and sensor data are continuously collected and integrated into the digital twin model, then monitoring accuracy and predictive capabilities are improved, but data processing requirements and computational resources increase
Solution Approach 1:
The system processes and analyzes data at the entity level rather than treating the entire building as a single unit. Each entity (space, system, equipment) has its own digital twin that processes relevant operational data and sensor readings locally. This localized processing reduces the computational burden on the central system while maintaining high monitoring accuracy for each specific entity.
Solution Approach 2:
The system performs preliminary data processing, filtering, and validation at the edge devices and entity level before transmitting processed information to the central digital twin model. This preliminary action reduces the volume of raw data requiring central processing, thereby lowering computational resource consumption while preserving measurement precision.
3Ease of operation
If the system provides comprehensive visualization options (2D, 3D, AR representations) and detailed entity-level information, then user control and monitoring capabilities are improved, but interface complexity and data presentation requirements increase
Solution Approach 1:
The visualization interface dynamically adapts to user needs and context. Users can switch between 2D, 3D, and AR representations based on the task at hand. The system automatically adjusts the level of detail displayed for different entities, providing comprehensive information when needed while simplifying the view during routine monitoring. This dynamic adaptation maintains ease of operation without requiring a permanently complex interface.
Solution Approach 2:
The system provides multiple dimensional representations of the same building data: 2D plans for architectural overview, 3D models for spatial understanding, and AR views for on-site context. Each dimension serves specific user needs and can be selected based on the monitoring or control task. This multi-dimensional approach enhances user capability without forcing all information into a single complex interface.
4Extent of automation
If AI algorithms are deployed for predictive analytics and automated maintenance scheduling, then facility operation automation is improved, but algorithm complexity and implementation difficulty increase
Solution Approach 1:
The entity-based digital twin framework enables systems and equipment to essentially self-monitor and self-diagnose through their individual digital twins. Each entity's digital twin continuously compares actual performance against expected parameters, automatically detecting anomalies and predicting failures before they occur. This self-service capability reduces the need for complex centralized AI algorithms while achieving high levels of automation.
Solution Approach 2:
The system implements continuous feedback loops where operational data and sensor readings are constantly fed back into the digital twin models, which then generate predictions and recommendations. This feedback mechanism enables automated maintenance scheduling and operational optimization without requiring overly complex algorithms, as the system learns and adapts from continuous data feedback.

AI summary
Systems, methods, and apparatus for building management are described. The methods, among other benefits, improve the decision-making effectiveness and efficiency of entity-based building management. An example method includes modeling and managing a building on an entity level by dividing the building and its related information into one or more entities, where a management result is presented in a two-dimensional (2D) representation, a three-dimensional (3D) representation, or an augmented reality (AR) representation. Another example method includes using a predictive artificial intelligence (AI) model to manage a building on an entity level by dividing the building and its related information into one or more entities, where the predictive AI model is a multi-input multi-output system.
