My desk is at the warmest place in the building - it's at an upper corner of the building, south facing and at the end of a room. I had to come up with some metric and this is the first year that it got so bad that I had to bailout and I sent everyone else home too, so I've set 30C at my desk as a first threshold. I'll probably lower it. I am the H&S bod, and shortly I'll be first aid accredited (again). Mind you I've done first aid for sailing and skiing back in the day too, so I know what you are supposed to do when hit by an avalanche ("swim" and pray, or soil yourself and pray - which is more likely) and how to treat or at least mitigate hypothermia. For some reason we have had loads of practice in working from home recently. I'm an expert in VPNs and all my staff have home phones virtually wired up to our PBX.
