Exchange HVAC Model (Systems)

Exchange of information about configuration, size, location, connection and technical data of HVAC systems including both the components and the distribution elements.

Please ensure that you have read the process mapping document HVAC Engineering before proceeding with this exchange requirement.

This exchange requirement describes the information to be provided about ducted HVAC systems. It allows for the provision of information at various stages during the design process including:

• Representation of components and their relation to spatial structures (sites, buildings and spaces) without connection to systems
• Line based representations at early design stages that enable routing, terminal location and main plant location information to be exchanged;
• Full 3D shape representations at detailed design stages that enable coordination between different building services systems, between services and structure and between services and the building construction elements.
  Information items that may be required about HVAC systems include:
• System name
• Terminal type, size, location, orientation, airflow rate, discharge velocity, pressure drop; supply air temperature may also be included for supply air systems.
• Duct section size, shape, location, flow rate, air velocity, pressure drop
• Duct fitting type, size, location, pressure drop
• Equipment type, size, location, pressure drop
• Shape of elements
• Connections between elements in the ductwork system
• Material from which elements are constructed
• Classification of elements
  Constraints that have been applied during the design of the ducting systems to limit or control duct sizing or equipment selection may also be included as part of the exchange requirement. These should be identified as a requirement by the user. Particular constraints considered include:
• Limiting pressure drop in a ductwork section
• Limiting velocity in a ductwork section
• Limiting dimensions for a ductwork section (height, width, diameter)
• construction standard
• Duct sizing method
