[Equest-users] loop operation controls

[Bishop, Bill]

Andrew,
 
I believe the conservative approach, and the intent in Appendix G., is
to keep everything the same between the baseline and proposed models
unless it is specifically addressed by 90.1. I model loop operation the
same in my proposed and baseline designs. "Standby" will use
considerably more pumping energy than the other options so try to
determine how the proposed design will be operated. Dedicated heating or
cooling loops are often operated on seasonal schedules.
 
Regards,
Bill

Hi!
 
I'm creating a baseline building with ASHRAE 90.1 and I would like to
know how should I input loop operation controls: Standby or demand.
 
Thanks to all!!!
