> What if something goes wrong and all the children roast alive or something? Then the parents would sue. It'll never happen today, people are terrified of being wrong so no is always the easiest answer.

I guess I sometimes agree with this sentiment, but this seems like an inappropriate place to invoke it. Is it really so insanely risk averse to get professional HVAC people to install and maintain the HVAC system for a large public facility?

If you mean in the past, this setup was probably state of the art back in the 80s. Multiple buildings networked together? Doubt that there were many HVAC guys setting that up back then.

If you mean today, sure, but why replace something that has worked so reliably without fail?
