Power Exhaust
(OP)
What are the basic issues to consider when deciding whether an HVAC unit will require "Power Exhaust"?
Example: New HVAC unit with outside air economizer & demand-control ventilation serving a high-school cafeteria.
Thank you.

I would look into and AAON unit with enthalpy wheel if it is DX. They have a power relief fan. You can get all kinds of options, hot gas reheat and return air bypass.
Barometric relief only works for retail strip malls where there is no neturn ductwork.
