A building has fan-assisted ventilation and no mechanical cooling system. Does this qualify as natural ventilation?

What options are available to mechanically ventilated projects outside the U.S. to meet this prerequisite?

NC-v4 EQp1:Minimum indoor air quality performance

Air Intake Minimum Separation Distance - distributed mechanical ventilation system

Hi, 

I am supporting the design of a large students house, more than 700 hundresds rooms.

For technical, and economic, reasons the systems design team is considering to implement a distributed mechanical ventilation system, every room will have a VMC integrated into the windows frame or in the external wall, instead of a centralized plant.
With this configuration it is not possible to respect the minimum distance between external air intake and external air outlet as represented in table 5.1 of Ashrae 62.1.To synthetize the issue, with the proposed configuration, external air intake and outlet will be pretty close, at about 1 meter of ditance.
I wonder if it is possible to use this system, maybe with alternative compliance path.

Thanks in advance for your attention

Francesco
