Template Rules
Create templates before creating the building
Red font means reading from template
Red screen means you are editing a template
To revert to the template value use the following:
Click the red triangle in the top left hand corner of field
Click the “Use Template” button when selecting another library member
Remove all data from field and click “Enter”

Screencast…Alternatives Example
Create a new linked alternative and edit a section of the new alternative (Plants)
Create 2nd Alternative Click on ‘Project Summary’ in Main Menu bar Link existing alt by clicking the ‘Link’ button at the top of Alt
1. This creates a new linked alt that has identical information in each section as the source alternative.
The 2nd alternative is created, now the ‘link’ will be broken Click on the linked symbol of the Plants section and select the
option to ‘Un-link Plants’ The Plants section is now editable
Open the Plants section in Alt 2 and change the efficiency of the existing equipment that was created in the previous Plants exercise so it is more efficient than the base alternative.
Calculate the exercise and compare the energy savings between the two alternatives.
