[Bldg-sim] Night purge

[Jeremy Poling]

Raj,

 

This is where Section G2.5 comes in - you can model the night purge as
an exceptional calculation methodology and take credit for it that way.
It will require a parametric model or even a third model (depending on
your approach to parametric models).

James,

           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.

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.

 

thanks,

raj
