Little bit after the pandemic they forced us to go back to the office (also, in summer, in spain, to a office with broken AC)

I don’t know what the relative humidity is like wherever in Spain you are, but if they had the windows open – and I assume that they could open and did, if the AC was offline and people were in there in the summer – and the humidity was low enough, could have thrown a portable evaporative cooler next to yourself. That can’t get things as cold as a sufficiently-powerful air conditioner, but it’s got a lot more punch than just a fan.
