[BLDG-SIM] eQUEST/economizer

[David Lanceta]

Hi everybody!

First of all, I would like to say thank you to everybody that have helped me in the past, I used to send emails to everyone but I´m sure I´ve forgotten some of them.

I´m simulating an office building with eQUEST, and I´m trying to know how much energy can be saved up. 

The HVAC system type is "Standard VAV with HW Reheat" for all the zones, the cold deck reset is 55ºF. I´ve also set up a drybulb temperature economizer, high limit 65ºF.

I think that when the drybulb exterior temperature is below 55ºF there should be free-cooling, but checking the temperature values this only happens when it´s under 49ºF  

does anybody know why it could be?

thanks
