[Equest-users] HVAC Loads Based on eQuest

[Hernandez, Arturo]

I guess the problem is when calculating loads you may want to be a
little more conservative with you internal loads and when you are doing
energy modeling you want to be more exact with your assumptions. In
addition, my understanding is that internal loads contribute to space
heating in eQuest load calcs. Which something that many engineers would
not feel comfortable with.

That's the way are offices typically do it as well (i.e. Trace for
loads, eQuest for energy).

 

I have found that when both programs use the same inputs for envelope,
lighting, misc equipment, etc., the two programs produce results that
are pretty close.

Just wondering... Has anyone based their HVAC design on eQuest results?
Typically we us Trane Trace for load calcs and do our energy models in
eQuest. However, this questions was brought up in our office. I just
wanted to see what everyone thought of this matter.
