Anderson,
I was checking this out recently I don't believe temperature or humidity setpoints are regulated by ASHRAE 90.1 during occupied periods. I think they primarily limit this through ASHRAE 55 regarding thermal comfort. Of course ASHRAE standard 55 is often not mandatory but it is certainly good practice. It goes without saying that several space types such as hospitals and labs have special temperature and humidity requirements that are industry-specific.
