I am told that there is a rule as to how much air con a company can use and they are very scared to break this rule, is there a certain point where the AC police say screw it and let them crank it up?
Is it a Canton Vaud thing then? I was told in 4 different places including Starbucks that they were not allowed to run the AC to make it more than 5 degrees less than outside. I was even told at the hotel they were not allowed to even install AC.
what they mean between the lines is they cannot be bothered to jack it up mainly because nobody really knows how to change the HVAC temperature and it takes a while to balance out to the new temperature.
I just asked in passing, like hey you seem to have AC units on the wall, any reason they are not like ummm on? And they explained this whole story.
Then I asked the hotel and got the same story and I heard others asking as well. It was pretty hot, this week will be bad too. I know that I was just at a hotel that allowed you to freeze the room, and it was hard to leave! I love to do that and many now stop it
The problem is that most offices built over the last 20 years or so have no refrigeration unit built into the system, as that would definitely have fallen outside the prescribed energy usage levels. Yes, they sometimes have "air conditioning" but it's only cooled by heatsinks, pulling air up from cellar levels and the like.
Recent innovations[1] in this area have improved things enormously, but it means that some of our offices can reach nearly 40C in the high summer. One that I was in for a couple of years was regularly over 30 first thing in the morning and would then rise during the day. Not helped by the idiots that insist on opening the blinds and windows when it's >30C outside.
[1] I believe it is now possible, especially near a river with the ability to use water to cool, to keep buildings cool enough in even the warmest conditions. That's what's being promised, at any rate.
We were also suffering in the office w/o AC, and the facilities told us that there are regulations in Zurich regarding how much energy you can use for cooling. As far as I understand, regular AC consume too much electricity to qualify. So, in the end they had to install some kind of water cooling system. Cold water goes through small copper pipes and cools air. It's better now, but it still can get uncomfortable during hot summers.
