Category

The category cannot be changed on the dialog.

 

The way line item data is entered depends on which of these 2 categories is selected:

 

Number of line items

Enter the number of line items to be inputs up to a maximum of 10. The number is fixed at 8 for cost data from the DesignBuilder category.

Line item n inputs

Each line item entered creates a cost line item in the EnergyPlus input and contributes to the total building cost estimate.

 

When using the DesignBuilder cost estimate, all Line items are obtained by first running the Cost and Carbon calculation. The line items are obtained from the sub totals in this output:

 

 

For details on how these costs are calculated, refer to the Cost and Carbon calculation section.

 

Alternatively, you can use your own line item data (as opposed to those calculated by DesignBuilder) by selecting a Component cost component from the User defined folder. Data from this folder has all fields editable.

 

Line items are reported by EnergyPlus and displayed in tabular form on the Summary tab of the Simulation screen:
