There are guidelines in the spec but I think they are quite high. There's also studies that high CO2 kills concentration in schools, those seem more reasonable.

Zoned systems are supposed to be able to handle individual zone heating/cooling issues, floor to floor without question should be able to be controlled. Entirely depends on what is installed and how it is controlled. This is an area where cost cutting happens. Generally there's a ashrae spec saying there is a minimum of five degrees °F between heating and cooling. So sure get a couple data loggers and report any findings to your manager.
