[Equest-users] Global Parameters

[Brian Fountain]

Good morning John,

It is indeed easy and that is exactly what I use Global Parameters for.

In the example I currently have open, I have a global parameter named “Infiltration multiplier”.

I use the abbreviation #PA to refer to the global parameter in a user expression.  (You can also spell out Parameter).  You need double quotes around the global parameter name.  Spaces are fine in the parameter name but capitalization is important.  In the user expression I multiply the zone infiltration by #PA(“Infiltration multiplier”).

In this example, I have a parametric run that cuts the infiltration in half by setting “Infiltration multiplier” to 0.5.

I hope this helps and that you are doing well.

Cheers,
Brian

CAUTION: EXTERNAL SENDER
I have never done global parameters before in eQuest. Is it possible to place a multiplier holder next to each CFM in a 50 AHU run, then place a 0.7 in parametrics so that all fans are reduced by 30%?

Hope it is easy.
