Back in 2012 to 2015 I worked most of the time I think in the radio lab at the company I worked for at the time. Temperature was often above 30 degrees in the summer. I didn't think much of it back then, went into office, started working and forgot everything but after a while I realized I was drinking 1.5l water during the work day without needing to visit the restroom and I would be exhausted when I came home.
It was noisy and warm but almost no interruptions and still very nice compared to insulating an attic in in the summer (I've done that too so I know.)
(This winter I tried working from the garage in December but at below 0C it gets impractical even with really warm clothing.)
