[Equest-users] Air Side Economizer savings

[Fleming, Joe]

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
