Joe,
So this worked for a multi zone building that I had. Thanks
I tried the same one for another building which has packaged Multizone,
Packaged VAV systems.
In addition to AIR Side economizer savings I am also going Night
setback, Fixing VAV's ,SA temp reset and finally the air side economizer
savings.
This is my Grid view. I really appreciate your help.
Amber,
I am getting negative heat savings. I am looking for a very conservative
number and that is why I chose 65 and 45. Thanks

Ok. Add Econo-Lockout and set it to yes. Then, when you are in the
Parametric Run Definitions dialogue box, click on grid view and compare
to the Baseline items.
For an accurate savings comparison, check to make sure Baseline has "NO"
compressor lockout and your run says "YES". Also check to make sure the
baseline OA control is set to "FIXED". (And you can compare other
inputs to make sure you are comparing the two systems the way you want).
Can you email the grid view?

Outdoor Air Vent &Economizer - OA Control - OA
temperature
This is the parameter I changed. And then I also inputted DBT High Limit
(65F) and DBT low limit (45F).
Thanks

Which keywords did you adjust in your parametric component?

Subject: [Equest-users] Air Side Economizer savings
I have been trying to model an existing building for which one of the
parametric run being Air Side economizer savings. Every time (for
different buildings) I do this run I come across negative savings. The
building is located in New York. The system is a multi zone system. I
hear that many people have across this situation. My cooling savings is
also minimal. Am I doing something wrong?
Please advice.
Thanks
Anusha
