Accessed from Parametric, Optimisation and UA/SA Analysis Settings dialog
Tip: The Optimisation Objectives dialog should be used with caution because there is no Cancel button, so once the dialog is opened, any changes made cannot be undone and upon closing of the dialog, the objective will be saved, replacing the previous one, with the settings currently being shown on the screen. In the case where you have mistakenly added an objective (or made incorrect changes while editing an existing one) you can close the dialog and then delete the incorrect objective on the Objectives tab on the main Edit Parametric, Optimisation and UA/SA Analysis Settings dialog. Alternatively if you haven't made any other changes since opening the main dialog , simply press Cancel on that dialog to lose all changes.
Your name for the objective for your reference, e.g. "Minimise ASHRAE 55 discomfort hours"
Select a predefined or custom objective Summary Output Key Performance Indicator (KPI) from the list.
Select whether you wish to maximise or minimise the selected objective. By convention objectives are usually set up in such a way that the objective is minimised. For example for a comfort-related objective it is usual to minimise discomfort rather than maximise comfort. Minimising both objectives means that the Pareto Front will form the lower left portion of the scatter plot showing all results which is the conventional way to display optimisation results.
The units of predefined KPIs are defined internally by the selected KPI itself. For custom KPIs the units are defined by the script that you write and in those cases it is usual to include the units within the name of the KPI. For example in the Custom Script KPI Tutorial the custom KPI created is given the name "EUI (kWh/m2)".
