3D Building Management System Rendering Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The large amount of Building Information Modeling (BIM) data associated with buildings, particularly when expressed in the Industry Foundation Classes (IFC) standard, leads to increased time and computing resources needed to generate three-dimensional building management systems, resulting in cluttered user interfaces and sluggish interactions, especially on mobile devices, which can hinder quick responses to real-time changes in building status.
Innovation Solution
Inputting BIM data and real-time building management system data into a three-dimensional graphics rendering engine to generate a three-dimensional building management system, which extracts relevant components, binds them to a user interface, and updates based on real-time data, using display rules and fidelity adjustments to optimize performance and responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If complete BIM data for all building systems is used to generate a three-dimensional building management system, then the system provides comprehensive building information, but the generation time and computing resources increase significantly
Solution Approach 1:
The patent extracts and displays only the most relevant building components and systems in the three-dimensional view based on user role, current operational context, and priority levels. Less critical components are omitted or displayed at lower fidelity, reducing the amount of BIM data processed and rendered while maintaining essential building information visibility.
Solution Approach 2:
The patent applies different levels of detail and information density to different regions or components within the three-dimensional building model. Critical systems receive high-fidelity representation with detailed parameters, while non-critical areas use simplified representations, optimizing the balance between information completeness and processing requirements.
2Loss of information
If complete BIM data is used to generate a three-dimensional building management system, then comprehensive building information is provided, but the user interface becomes cluttered
Solution Approach 1:
The interface extracts and prioritizes display of only the most relevant building components, systems, and parameters based on user role, current operational context, and predefined priority levels. Less critical information is omitted or made accessible through on-demand drilling down, preventing interface clutter while preserving access to comprehensive building data.
Solution Approach 2:
Different regions of the user interface display information at different levels of detail appropriate to their function. Critical control elements and alarm indicators receive prominent, detailed display, while secondary information uses simplified representations, creating a clear visual hierarchy that improves ease of operation.
3Loss of information
If complete BIM data is used to generate a three-dimensional building management system, then comprehensive building information is provided, but interaction becomes sluggish
Solution Approach 1:
The system extracts and processes only the essential BIM data required for current operational tasks and displays it in optimized three-dimensional representations. By reducing the volume of processed data while maintaining critical building information, rendering and interaction speeds are significantly improved, enabling responsive operator input.
Solution Approach 2:
The patent implements variable fidelity rendering where critical building systems and components are displayed with high detail and interactivity, while non-critical areas use simplified geometries and reduced data processing. This selective approach maintains comprehensive building information availability while optimizing interaction speed for essential operations.
