[Equest-users] ASHRAE envelope values in eQuest for LEED

[Nick Caton]

Hey Tai,

 

LV-D reported U-values include something for exterior air films that you
won't see while defining the constructions... Maybe that's the
difference you're seeing?

 

I've had to explain that to a reviewer before, and recall responding
with screen grabs illustrating the DD layer inputs/properties and
resulting overall construction U-value.  That buried the issue.

Hello All,

If a reviewer was to find the U-value of the walls and windows, I'm
assuming they would go to SIM file under LV-D and find what the average
assembly value is?
I ask because when I create the baseline I use the DD mode to make the
Assembly value as per ASHRAE 90.1-2004.
But i'm finding different values between the DD and LV-D reports.

Hoping someone with experience would be able to comment.

Thanks,

Tai Lieu
