We describe possible strategies to build, edit and develop a network in a step-wise fashion in a building with several storeys.
For the described actions, open a model of the discipline.
Zur allgemeinen Strategie
To make the job effective, consider the space requirements of the system from the beginning. Work with the expected dimensions, and think about insulation as well as possible size changes using a network calculation.

Working in the riser shaft
|
The positions of the ventilation centre and manhole are set with the complete building design. You know how to measure the total air volumes and can measure the cross section of the main channels with this.
You develop the network in a step-wise fashion using these assumptions. Simulate the consumer in this early stage using load objects in order to calculate the network in each processing step  . Enter the estimated or roughly calculated demand value in these objects.

Open the next storey and take all  media into the continuous ventilation duct. Produce a branch and end it with a load object  in order to prepare the distribution on the storey.

You can transfer the prepared ventilation ducts of one storey to all floors using Copy and Paste. You also take over the connected load objects and correct their discharge units to the conditions of the respective storeys.

Refine the network construction
While advancing in the design process, you can refine the network construction on the storeys. You split the bigger load objects into smaller units with more accurate values and calculate the system again and again.

If the positions of the objects with a dedicated purpose (Air TerminalPlenum) are clear, remove the load objects and attach the appropriated objects to the duct network.

Auxiliary functions and operations
Various help functions support the construction of a pipe network. Take advantage of these functions when required.

Edit ventilation system
Important!
If you shift a riser, then check the risers on the neighbouring storeys. The connected risers for all floors must stand superimposed over one another on all storeys after the operation is completed.
