[Equest-users] No Roof Conduction Losses

[Jae Koh]

As I can't check your project file but you may find the changes of the roof conduction by LS-E (Components) instead of LS-C(peaks of conditioned space). Also, if you remove the plenum at the top, the roof conduction should be affected to the conditioned spaces directly. 
And I recommend the EEM Wizard to quickly describe the alternative cases to your baseline model.
Good luck!
