As soon as you start having you own server/network rooms, yes.

You will have to monitor your HVAC systems, your fire extinguisher systems, your alarm systems (for smoke and water leak detection), your electrical systems... You will need to make decisions about which type of system to install. You will have to set up maintenance and repair of these systems and interact with the specialized technicians who come to service them.

Not saying you have to become an HVAC expert, but you will definitely learn some stuff outside of computing/networking.
