The title says it all really

I work in a building where what was originally a large open plan area has been divided up into many separate offices. As is often the case when this happens, little thought is given to air conditioning routing and balancing. As a consequence some of the offices get very hot and stuffy.

In the recent run of hot weather in Melbourne my office was so hot I was sweating while just sitting at my desk and the air flow was so poor it was really hard to concentrate and stay awake!

Is there any legislation around this?
