[Equest-users] HVAC type for Exhaust Fans on parking lots

[Bishop, Bill]

Claudia,
 
If you are doing a LEED/Appendix G model, I suggest modeling it as a
process load (Direct Loads - Interior), with the load equal to the fan
power and with a schedule that approximates when the fan will run based
on CO2. The load and schedule should be identical between your baseline
and proposed unless you can justify it through an exceptional
calculation. See Dakota Kelley's email, attached.
 
Regards,
Bill

A non-conditioned underground parking lot has exhaust fans with VSD
which work according to CO2 levels.
How do I define this type of HVAC system?
 
Thanks
Claudia
