Select Calculation Base

Shows step-by-step how to select a calculation base for your heat load.

Before you begin

You have detected the building and would like to set the correct calculation base before the calculation.

You would like to set the correct calculation basis for an approximate heat load calculation.

Navigate to:

Module overview ➤ Heat load ➤ Project level ➤ General heat load data

Procedure

Open the drop-down list Basis of calculation.

The list of available standards depends on the selected region.
Select Approximate heat load.

Results

You have selected the calculation basis for an approximate heat load calculation.

What to do next

You can now define the general heat load data and then perform the quick entry.
