<DIV> Thank you for your responce. I am really confused because having night purge requires that the base case and proposed case have different operating schedules. The proposed case controls will check the space and outdoor temperatures at night and run the fans.</DIV>
<DIV>However for the base case the fans are turned off at night. Dosen't ASHRAE 90.1 appendix G require us to have the same operating schedules for the base and proposed case.</DIV>
<DIV> </DIV>
<DIV>thanks,</DIV>
