The AV lab gets screwed. You're running the coax they need through the

equipment.

There are double-shield coax solutions for noisy risers.  The outer
shield is grounded to the conduit, while the inner shield is grounded at
the source equipment.  One has to be sure that the voltage differential
between shields is kept as low as practical, which means paying
attention to grounding for the conduit AND equipment.
