Systems
Systems
Systems are modeled with the system
marker tag. Systems the logical structure of buildings meant to group multiple equip
that serve a similar purpose. The members of a system do not necessarily have to be in the same physical space
. For example, a Chilled Water System may consist of equipment within the Chilled Water Plant, but also Air Handlers with Chilled Water Coils fed by that plant. Systems do not represent a physical structure unless also paired with an equip
tag (e.g., if system
is used in conjunction with a plant-equip
).
Tags
System entities should define a siteRef
tag for their parent tag. All systems subtype from system
and are then kebab cased with other valid tags to create the conjunct (e.g., chilled-water-system
).
It is also valid for systems to define a systemRef
tag to describe a sub-system or primary/secondary relationship. This relationship would imply logical containment, i.e., all members of a sub-system automatically belong to the referent system as well.
Examples
Here are examples of a properly tagged system and member equipment:
