Design Energy Code Equivalent %

The Design Energy Code is an input in General Inputs section 1. For whole building projects that have the selection of "Energy Model Status" of "Will NOT be Modeled" or "Will be Modeled", but the "Has the project established an EUI yet?" is not checked, the Design Energy Code selection sets the SAVINGS for the project.  The SAVINGS percentage is a code equivalent % savings of the selected code to the code basis for the 2030 Challenge, which is ASHRAE 90.1-2003.
