Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional building management systems are used, then system complexity is reduced, but reliability of building event tracking and compliance monitoring deteriorates
Solution Approach 1:
The patent introduces a blockchain ledger as an intermediary layer between building event data sources and compliance monitoring systems. This blockchain intermediary provides immutable recording of building events, ensuring reliability without requiring complex point-to-point verification systems between multiple stakeholders.
Solution Approach 2:
The blockchain-based building action management system serves multiple functions simultaneously: it records building events, tracks compliance, enables predictive maintenance, and provides a unified data platform for multiple data sources (IoT sensors, building management systems, external databases), reducing the need for separate specialized systems.
2Measurement precision
If comprehensive building event data collection is implemented, then measurement precision of building conditions is improved, but loss of time for data processing increases
Solution Approach 1:
The system performs preliminary actions by continuously recording building events in the blockchain ledger as they occur, rather than batch-processing data later. This real-time recording approach ensures measurement precision is maintained while reducing subsequent data processing time, as the data is already structured and verified when needed for analysis.
Solution Approach 2:
The patent creates copies of building event data in the immutable blockchain ledger, allowing multiple systems and users to access identical verified data simultaneously without requiring sequential access or complex data synchronization, thereby reducing data processing time while maintaining precision.
3Productivity
If real-time building monitoring is implemented, then productivity of maintenance operations is improved, but use of energy for data collection and processing increases
Solution Approach 1:
The system enables self-service maintenance by providing real-time building condition data and predictive analytics that allow facility managers to autonomously identify and address issues without constant external intervention. This improves maintenance productivity while the energy consumption is distributed across the blockchain network rather than centralized, reducing overall system energy overhead.
4Reliability
If blockchain technology is implemented for building management, then reliability of data integrity is improved, but device complexity of the system increases
Solution Approach 1:
The blockchain ledger serves as a trusted intermediary that simplifies the architecture by providing built-in data integrity verification through its immutable structure. This eliminates the need for complex external verification systems, digital signature implementations, and multi-party consensus protocols that would otherwise be required to ensure data integrity.
Solution Approach 2:
The system uses blockchain's inherent copying mechanism where identical verified data is distributed across network nodes, providing automatic data integrity verification without requiring complex checksum algorithms or redundant verification protocols, thus improving reliability while managing complexity.

AI summary
Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: obtaining first building event transaction data of a building using a first data source; recording a first blockchain block in a blockchain ledger, the first blockchain block having a timestamp and the first building event transaction data; obtaining second building event transaction data of the building using a second data source; recording a second blockchain block in the blockchain ledger, the second blockchain block having a timestamp, and the second building event transaction data; examining data of the first blockchain block and the second blockchain block; and providing one or more output in dependence on the examining.
