We are dealing with project with underground garage, where adjacent spaces are technical rooms. Can we transfer the air from the garage to the technical rooms to ventilate them? Do we need to keep positive pressure in these rooms if they are not occupied spaces?
Thanks for help

Could you provide clarification on what you mean by technical rooms? Parking garage is classified as Class 2 air, so you can't transfer to Class 1 spaces, which includes data rooms.

ASHRAE 62.1 excludes equipment rooms and storage rooms from the definition of occupiable spaces. If your technical rooms are within this definition, they don't need to be ventilated.
