[Equest-users] Question on Energy consumption results

[Nicholas Caton]

Hello!

If I had to make a guess, a relatively common issue I’ve uncovered would start with checking whether the glass being revised, before editing, is using the glass library specification method (i.e. your glass is defined via code like 2004).  In that scenario, you are permitted to add/define inputs used with the simplified method of defining glass like VIS-TRANS and GLASS-CONDUCT through parametric inputs, but they won’t “hook” and accomplish anything.  You’d need to swap your glass inputs over to simplified first, or else look up another library entry appropriate for your VLT switch and edit that assignment instead.

If this doesn’t cover it, there are a myriad of daylighting-related inputs which may throw off the expected behavior.  It would probably be most time-efficient for you to share a copy of the model files (pd2/inp) with the list, and to indicate the specific window(s) you are expecting to observe results by editing.  It would also in that context be helpful to know whether you used the wizards to help you set up the space daylighting inputs before toggling to “No” daylighting.

What's the VLT values thay you're using?

Hi,

I am modelling on Design Development wizard, I am changing VLT of glass , but there is no change in area lights consumption.
Why is it so ?

I have switched off daylight control.
When I switch on , the results show changes.

Regards
