Solution Overview
Problem
Existing building management systems (BMS) lack the ability to automatically implement control strategies in response to changes in building configurations, such as changes in spaces or equipment, leading to inefficiencies and potential comfort issues.
Innovation Solution
A BMS that includes circuits capable of receiving inputs to invoke control strategies, performing queries to identify relevant equipment and points, and automatically modifying values or operating equipment to execute the control strategies, even in response to changes in building configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a BMS uses traditional manual control strategy implementation, then system complexity is reduced and ease of operation is improved, but productivity decreases and loss of time increases due to manual configuration changes
Solution Approach 1:
The system automatically detects configuration changes (spaces, equipment, points) and self-implements control strategies without manual intervention. The BMS queries for affected equipment and points, then automatically modifies their values to execute the control strategy, enabling the system to serve itself in responding to configuration changes.
Solution Approach 2:
Control strategies are pre-defined in the system with associated rules and conditions. When configuration changes occur, the system has pre-programmed logic to identify affected equipment and points, and pre-established control strategies are automatically invoked, eliminating the need for manual strategy creation or configuration.
2Loss of time
If a BMS implements automatic control strategy execution, then productivity improves and loss of time is reduced, but device complexity increases and ease of operation deteriorates
Solution Approach 1:
The system automatically queries for equipment and points affected by configuration changes and self-executes control strategies without requiring operator intervention. This eliminates manual time-consuming tasks while the underlying complexity is managed by the automated system rather than the operator.
Solution Approach 2:
The BMS acts as an intermediary between configuration changes and control execution. It receives notifications of configuration changes, queries for affected equipment and points using predefined rules, and automatically implements control strategies, serving as an automated mediator that simplifies the operator's task while handling the complexity internally.
3Reliability
If a BMS manually tracks configuration changes, then measurement precision is improved and reliability is maintained, but productivity decreases and loss of time increases
Solution Approach 1:
The system receives automatic notifications when configuration changes occur (spaces added/modified, equipment added/modified, points added/modified). This feedback mechanism ensures the system is immediately aware of changes and can reliably trigger the appropriate control strategy execution without manual tracking.
Solution Approach 2:
The BMS automatically queries for affected equipment and points using predefined rules and relationships, then self-executes control strategies without manual intervention. This maintains reliability through automated tracking while dramatically improving productivity by eliminating manual configuration monitoring and implementation.

AI summary
A building management system includes (i) one or more building systems including equipment configured to serve one or more spaces in a building and (ii) one or more circuits. The one or more circuits are configured to receive an input to invoke a control strategy to modify a condition of the one or more spaces; define an output of the control strategy where the output relates to a modification that impacts at least one of a location, an equipment type, or a point type; perform a query to identify one or more points associated with the output where the one or more points are defined in terms of at least one of the location, the equipment type, or the point type; and automatically modify one or more values of the one or more points to implement the control strategy.
