Optimisation Design Variable

DESIGN VARIABLE

Variable type

Select the variable type from the list.

Note: In current beta versions all variables are listed for selection regardless of the state of the model and care must be taken to select variables that are appropriate. For example, if the Scheduled natural ventilation model option is used then changes in the % External window opens variable (which only applies to Calculated natural ventilation) won't affect results.

Min value

The lowest value that this numeric design variable can take on. This option is only visible when a numeric variable type has been selected (above).

Max value

The highest value that this numeric design variable can take on. This option is only visible when a numeric variable type has been selected (above).

Step

Not used yet. This option is only visible when a numeric variable type has been selected (above).

Values

Click on the browse button to open a list of components or templates for selection. Items can be selected by checking the appropriate checkboxes.

When a template is selected as the variable type, one of the selected templates from the list are loaded in each iteration of the optimisation analysis.

This option is only visible when a list variable type has been selected (above).

TARGET

Target objects

This option allows you to select one or more object(s) to which the variations are to be applied.

Note: In the current v3 software this option is not selectable and all variations are applied at the building level. While this can be limiting, it is still possible to achieve some control through appropriate use of hard and default settings at block, zone, surface and opening levels in the model.
