Model HVAC

Before modelling HVAC, the correct database elements should already be present in the Model Explorer, for example: a World, Site and Zone should exist.

Database Hierarchy

All database elements are owned by other elements, therefore elements must be created in a strict order.

The following database elements are common to all the Design disciplines:

• World

• Site

• Zone.

HVAC-Specific Hierarchy

Below the ZONE level in the HVAC module, the HVAC-specific elements are:

• HVAC (HVAC)

• BRANCH (BRAN)

• HVAC Component(s).

HVAC (HVAC) Element

The HVAC (HVAC) is a top level element in the Design database under which Branch (BRAN) element(s) are created.

BRANCH (BRAN) Element

The Branch (BRAN) is a sequence of HVAC component elements running between two points:

• Branch Head

• Branch Tail

HVAC Component Element

HVAC Component element(s) are owned by branch elements.These components dictate the shape and geometry of the HVAC design. HVAC components can run from the head to tail of the owing branch but can also be connected to other branches.
