There are different areas in every plant. Some rooms are controlled while others are not. The area I work in is a controlled environment. So, it just depends.
I worked in an office with cubicles. There was air conditioning - heating and cooling. There were no windows to open. The facility had an excellent maintenance crew which kept things running smoothly.
