Building system with performance identification through equipment exercising and entity relationships

A method of a building system comprising:

• identifying, by one or more processing circuits, based on a relational model, one or more first relationships between a first building entity of a building and a second building entity and one or more second relationships between a third building entity and the first building entity, wherein the one or more first relationships indicate an expected effect on the first building entity caused by operation of the second building entity when the building is not experiencing a performance issue, and the one or more second relationships indicate an expected effect on the first building entity caused by operation of the third building entity when the building is not experiencing a performance issue;
• selecting, by the one or more processing circuits, a first exercise for the second building entity to test the one or more first relationships between the first building entity and the second building entity;
• exercising, by the one or more processing circuits, the second building entity by operating building equipment represented by the second building entity in accordance with an adjusted setting defined by the first exercise to generate first building entity data associated with the second building entity, the first building entity data indicating a result of the first exercise;
• identifying, by the one or more processing circuits, that the building is experiencing the performance issue by analyzing the first building entity data and the one or more first relationships, wherein the performance issue is identified in response to determining, based on the first building entity data, that operating the building equipment represented by the second building entity in accordance with the first exercise did not produce the expected effect on the first building entity;
• determining, by the one or more processing circuits based on the first building entity data, that the building equipment represented by the second building entity did not cause the performance issue;
• in response to determining that the building equipment represented by the second building entity did not cause the performance issue, exercising, by the one or more processing circuits, the third building entity by operating building equipment represented by the third building entity in accordance with an adjusted setting defined by a second exercise to generate second building entity data represented by the third building entity, the second building entity data indicating a result of the second exercise;
• determining, by the one or more processing circuits based on the second building entity data, that the building equipment represented by the third building entity caused the performance issue;
• and
• automatically causing an action to be initiated in response to determining that the building equipment represented by the third building entity caused the performance issue, the action comprising attempting to repair the building equipment represented by the third building entity, shutting-down the building equipment represented by the third building entity, or working around the performance issue by directing control activities around the building equipment represented by the third building entity.

A building management system of a building comprising:

• one or more memory devices configured to store instructions;
• and
• one or more processors configured to execute the instructions causing the one or more processors to:
• identify, based on a relational model, one or more first relationships between a first building entity and a second building entity and one or more second relationships between a third building entity and the first building entity, wherein the one or more first relationships indicate an expected effect on the first building entity caused by operation of the second building entity when the building is not experiencing a performance issue, and the one or more second relationships indicate an expected effect on the first building entity caused by operation of the third building entity when the building is not experiencing a performance issue;
• select a first exercise for the second building entity to test the one or more first relationships between the first building entity and the second building entity;
• exercise the second building entity by operating building equipment represented by the second building entity in accordance with an adjusted setting defined by the first exercise to generate first building entity data associated with the second building entity, the first building entity data indicating a result of the first exercise;
• identify that the building is experiencing the performance issue by analyzing the first building entity data and the one or more first relationships, wherein the performance issue is identified in response to determining, based on the first building entity data, that operating the building equipment represented by the second building entity in accordance with the first exercise did not produce the expected effect on the first building entity;
• determine, based on the first building entity data, that the building equipment represented by the second building entity did not cause the performance issue;
• exercise, in response to determining that the building equipment represented by the second building entity did not cause the performance issue, the third building entity by operating building equipment represented by the third building entity in accordance with an adjusted setting defined by a second exercise to generate second building entity data represented by the third building entity, the second building entity data indicating a result of the second exercise;
• determine, based on the second building entity data, that the building equipment represented by the third building entity caused the performance issue;
• and
• automatically cause an action to be initiated in response to determining that the building equipment represented by the third building entity caused the performance issue, the action comprising attempting to repair the building equipment represented by the third building entity, shutting-down the building equipment represented by the third building entity, or working around the performance issue by directing control activities around the building equipment represented by the third building entity.
