General Help - SAP and U-value modules

Starting a new project

JPA Designer organises and saves calculations in project ﬁles, which have the extension .JDP. You can save multiple SAP, U-value and PV & Wind Turbine payback calculations in the same ﬁle. Calculations are created, saved and managed in the JPA Designer Project Manager window which lists all the calculations in the current project.

Whenever you start JPA Designer the program creates a new blank project which you can start using straight away. You can also create a new project at any time by selecting File>New Project from the main menu, or clicking the New Project button on the toolbar.

You can change the default project name 'A blank project' to something more useful:

Click once on the project name then select Edit>Rename selected item. The Project name dialogue opens.
Enter the new name for your project, then click OK.
The project is renamed.
The project name does not affect the calculations in any way.

Adding calculations to a project

You can add new calculations to a project in the Project Manager window. To add a new calculation to a project:

From the menu bar select Insert>select the calculation you want to create from the list. The Description dialogue opens.
Type a name for the calculation in the Description dialogue and click OK. The new calculation is added to the project.
To add multiple calculations / options to a single project file follow steps 1 and 2 again.

Duplicating calculations:

If you want to prepare a calculation which is very similar to an existing calculation in a project you can duplicate the calculation and then make your changes to the copy, without affecting the original calculation. To duplicate a calculation:

In the Project Manager window click
once on the calculation to select it.
From the menu bar select Edit> Duplicate item. The Description dialogue opens.
Type a name for the duplicate calculation and click OK. A copy of the original calculation is added to the project. You can now work with the duplicate calculation in the usual way.
