24 be she "doesn't believe them"
But it wont be 24 degress all the time, air conditioning cant do that as far as I am aware.
Generally AC senses it is getting too warm then turns on for a bit. The AC then over compensate and it gets too cold so it turns off for a while. It then becomes too hot and they turn on again.
Also you have to take into account the differences in physical mass if she is a particularly small woman or you have a large surface area in comparison to your overall weight you will feel alot colder than some one else.
In my office their have been many many arguments over the air conditioning, but the workers change very quickly.
At one time people have demanded it as low as 21 degrees where as now its at 26 degrees with people complaining if it goes lower. (which I personally think is now a bit warm)
Being a baldy sitting directly in front of the air conditioning can be annoying as I often have to wear a hat while at work.
When we had it at 21 degrees i'd often have several layers on then go outside on to realise it was 28 degress or something and suddenly be sweating like the pig that knows its dinner.
I just think the air conditioning is a very personal thing and very difficult to get right.
I reckon the main problem is putting too many people/computers in the same room.
This means you have to use quite large air flows try and keep a steady temperature this has 2 problems.
1. People in the draughts are too cold, people not in them are too warm.
2. Air flow cooling increases how different individuals feel the temperatures.
Individuals with a larger surface area to volume are very quickly cooled.
Individuals with a small surface area to volume will retain their heat for longer.
Therefore thin or small people general dislike the way AC tends to over then under compensate. As they need a steady air temperature for them to regulate their own temperature.
This is what happens to me sometimes when the AC is off I can almost feel sweat starting to form then suddenly its back on Im freezing.
