We already know that Weiss uses those Glyphs practically every time in combat and she has never been one to run out of energy except that one time she created what seems to be a hundred glyphs in Players and Pieces.

So, maybe for some other people using a Semblance will consume a large amount of Aura. But for Weiss? I'm almost surprised she didn't use her glyphs everywhere beyond combat, though that may just be that Semblances are in general banned in the Academy except specific classes and free time.
