Cold weather issues

I labor in a corporate office building. There are many companies that all labor in the same building plus our office is on the fourth floor. I care about our job plus I have been with our corporation for about many years now plus I am about to have a major promotion. However, I absolutely can’t deal with how cold our office gets during the day. I understand that the Heating plus Air Conditioning system isn’t controlled in our office, however I don’t understand why it is always cold cold plus the a/c is blasting. I have to wear about 3 jackets to labor everyday plus I am still cold. I wear gloves while I am at our desk because our fingers are always so cold. I have previously brought up the issue to our boss, however they absolutely don’t seem to care. They make it seem care about they have more important things going on than me being cold while I am at work. I want to go to higher management plus tell them, however I don’t think that would help our case either. I am going to have to just suck it up plus bring in a space gas furnace to labor so that I can be productive. I guess that our building doesn’t allow space heaters, however I will just have to sneak a single in while the front desk lady isn’t looking. I absolutely hope I don’t get in trouble for having a space heater, however in the end I have to stay overheated and this seems care about our only option. I will just use the space gas furnace until someone tells me I have to stop.
