High-Level Design Process for Each System

Water/Fire System Design Process

Step-by-step
  1. Starting Point:

    Add the Flow Source as the system's connection point.

    Input source details like pressure and height.

  2. Adding Equipment:

    Place key equipment like Hot Water Plant and Storage Tanks.

  3. Pipe Layout:

    Draw Pipes from the Flow Source to the Equipment.

    Use Risers for multi-floor connections.

  4. Adding Demand:

    Place demand points such as Fixtures or Nodes (sprinklers).

    Connect to these using pipes.

Heating/Chilled System Design Process

Step-by-step
  1. Starting Point:

    Begin with the primary equipment, such as Heat Pumps or Chillers.

    Enter system details like delta T.

  2. Adding Equipment:

    Include any additional equipment like Buffer Tanks or Headers.

  3. Connecting Components:

    Draw the main Pipes from the equipment through the floor layout.

    Use Risers for multi-floor connections.

  4. Adding Demand:

    Place Emitters such as Radiators or Fan Coil Units.

    Ensure each emitter is connected to both flow and return pipes in the correct order.

Underfloor Heating (UFH) System Design Process

Step-by-step
  1. Starting Point:

    Place the Manifold(s).

    Review manifold Properties.

  2. Connect Rooms:

    Use the manifold properties to connect Rooms to the manifold.

    Pipes between the manifold and rooms are automatically routed based on the layout, always taking the shortest path.

    Verify that each room has a Door or a Wall Passthrough for pipe entry. Without a door or passthrough, loops cannot generate.

  3. Add Unheated Areas:

    Add Unheated Areas to avoid heating below items such as kitchen islands, bathtubs, or below-floor main pipes or structural elements.

    You can also use unheated areas to straighten or optimize loop routing.

  4. Add Heated Areas:

    For rooms exceeding the maximum loop length, add Heated Areas to divide the space into multiple loops.

Direct edits to pipe layouts are not possible. Instead, manipulate the layout by:

  • Moving doors or wall passthroughs.

  • Adjusting the manifold location.

  • Changing room properties.

  • Adding new unheated/heated areas.

Ventilation / Ductwork System Design Process

Step-by-step
  1. Starting Point:

    Place the Air Handling Unit (AHU).

    Configure AHU Properties.

  2. Duct Layout:

    Draw the main Ducts from the equipment through the floor layout.

    Use Risers for multi-floor connections.

  3. Adding Demand:

    Place Diffusers or Grilles to distribute air.

Gas System Design Process

Step-by-step
  1. Starting Point:

    Add the Flow Source as the system's connection point.

    Input source details like pressure and height.

  2. Pipe Layout:

    Draw the main Pipes from the flow source through the floor layout.

    Use Risers for multi-floor connections.

  3. Add Valves:

    Add components like Regulators, Filters, or Meters.

  4. Adding Demand:

    Place Appliances like boilers, stoves, or heaters and input the correct Properties at the appliance.

Ensure the pressure at the flow source is higher than the gas regulator, and ensure the pressure at the gas regulator is higher than the gas appliance.

Drainage System Design Process

Step-by-step
  1. Starting Point:

    Add the Flow Source as the system's connection point.

  2. Adding Equipment:

    Place key equipment like Pits.

  3. Pipe Layout:

    Draw Pipes from the flow source to equipment and along the main layout.

    Use Stacks for multi-floor connections.

  4. Adding Demand:

    Place demand points such as Fixtures or Nodes.

    Connect to these using Pipes.
