Building Data Enrichment Loop for Context-Aware Digital Twins
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building management systems lack dynamic, scalable, and adjustable solutions for holistic management of building systems, as they operate independently without knowledge of the building's overall context.
Innovation Solution
A building system that utilizes a digital twin and an enrichment loop to receive events from various sources, identify contextual data, enrich events with this data, and provide enriched events to consuming systems for holistic management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If discrete predefined controlling systems operate each subsystem individually, then each subsystem can be controlled independently, but holistic management of the building is not achieved and systems lack knowledge of the overall building context
Solution Approach 1:
The patent merges discrete subsystems into a unified building management system that processes events from multiple sources (HVAC, security, fire response) through a common event processing pipeline. The system combines separate controlling functions into an integrated platform that can holistically manage the entire building while maintaining individual subsystem independence through modular event sources and consuming systems.
Solution Approach 2:
The building management system implements a universal event processing platform that handles multiple types of building subsystems through a single integrated architecture. The system provides multi-functional capabilities including event enrichment, contextual data integration, and holistic building management while serving diverse subsystems through a common digital twin representation.
2Productivity
If building systems operate without contextual information, then system operation is simpler, but decision-making quality and operational efficiency are reduced
Solution Approach 1:
The system performs preliminary enrichment of events with contextual data from the digital twin before events are processed by consuming systems. By pre-loading contextual information (building geometry, equipment locations, operational parameters) into the event stream, the system enables faster decision-making without requiring complex real-time queries during operational decisions.
Solution Approach 2:
The digital twin serves as an intermediary between raw building data and decision-making processes. It translates complex building contextual information into enriched events that consuming systems can directly utilize, eliminating the need for systems to independently access and interpret raw building data while maintaining operational efficiency.
3Adaptability or versatility
If a building management system is designed to be dynamic and scalable, then it can adapt to different building configurations, but system complexity increases
Solution Approach 1:
The system segments building management into independent event sources, event processing pipelines, and consuming systems. Each subsystem (HVAC, security, fire response) operates as a separate event source that can be independently added or removed. The digital twin is segmented into manageable components representing different building elements, enabling scalable deployment without increasing overall system complexity.
Data Source
AI summary
A building system including one or more memory devices having instructions stored thereon, that, when executed by one or more processors, cause the one or more processors to receive an event from an event source, the event comprising data and a timestamp. The building system operates to identify first contextual data describing the event in a digital twin, the digital twin comprising a virtual representation of a building, enrich the event with the first contextual data, and provide the enriched event to a consuming system, the consuming system generating an output event based on the enriched event. The building system operates to identify second contextual data describing the output event in the digital twin, enrich the output event with the second contextual data, and provide the enriched output event to the consuming system or another consuming system.
