Building Fault Emissions Modeling for Energy Waste Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing building management systems (BMS) fail to accurately determine the amount of energy wasted due to fault conditions, associated costs, and carbon emissions, leading to inefficiencies and unexpected downtime.
Innovation Solution
A BMS that includes fault detection rules to identify faulty building devices, calculates energy waste and emissions using a fault emissions model, and initiates automated actions to correct faults, such as generating work orders or alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a BMS monitors and controls building subsystems to improve efficiency, then building operations are improved and operating costs decrease, but the system cannot accurately determine energy waste due to fault conditions
Solution Approach 1:
The patent introduces an intermediary calculation process that uses fault detection data, operational parameters, and emissions models to estimate energy waste. This intermediary system bridges the gap between fault detection and accurate energy waste measurement by computing additional energy consumption based on fault duration, equipment type, and operational conditions.
2Object-generated harmful factors
If the BMS determines detailed fault emissions and energy waste, then carbon emissions tracking is improved, but system complexity increases
Solution Approach 1:
The patent segments the emissions tracking system into modular components: fault detection modules, emissions model databases, calculation engines for different equipment types, and reporting modules. Each component handles specific aspects of emissions tracking independently, reducing overall system complexity while maintaining comprehensive tracking capability.
Solution Approach 2:
The system performs preliminary actions by pre-configuring emissions models and fault detection rules before faults occur. Emissions models are pre-loaded with equipment-specific parameters, and fault detection rules are established in advance, enabling rapid emissions calculation when faults occur without requiring complex real-time analysis.
3Loss of energy
If the BMS implements automated fault detection and emissions calculation, then energy waste reduction is achieved, but the system requires more advanced processing capabilities
Solution Approach 1:
The patent implements partial action by focusing automated detection and calculation on high-impact fault conditions and critical equipment only. Rather than continuously analyzing all building subsystems, the system selectively applies automated emissions calculation to equipment where faults would result in significant energy waste, reducing processing requirements while maintaining effective energy conservation.

AI summary
A building management system (BMS) includes one or more memory devices having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations including using the operating data to evaluate one or more fault detection rules (624) to determine whether at least one of the plurality of building devices is experiencing a fault condition, in response to determining that at least one of the plurality of building devices is experiencing the fault condition, determining an amount of carbon emissions generated due to the fault condition based on a fault emissions model (676) associated with the fault condition and initiating an automated response based on the amount of carbon emissions associated with the fault condition.
