Grow room design

What about the air circulation? Grow tents will have intake and exhaust fans and carbon filters but what about the room itself? If the a/c is not used everyday, is it better to install a separate air intake for the room itself or is opening a window a few times a day enough? I don't want to use a/c excessively due to high energy consumption, but fresh air is a must.
