Body temperature regulation in schools

Hi

I want to support my daughter's school who have a small sensory room in a mainstream secondary school. At the moment they rely on heaters and desktop fans to help regulation, but the person leading the sensory room wants to get an air conditioning unit for climate control. She has been asked for research into whether this will make a difference in the colder months. I want to help, but I do not know where to start- can anyone here help me please.

Kind regards
