I guess the "don't wear ties" comment was meant to be less serious, but men's business clothing has driven a lot of office thermostats to 60⁰F over the course of my experience. Men in suits and ties are comfortable at the approximate temperature of a meat locker, while everyone else is freezing and energy is wasted. If the PM were serious about trendsetting to reduce energy use, he would ban the suit jacket and encourage men to wear shorts to work.

It's not just that, it's also that men have higher skin temps than women. If a man and woman were wearing the exact same clothes, in the exact same room, the man would still almost certainly be feeling warmer.

Is that effect mediated by body size, or is it true even when corrected for body size and shape?

[piva00]

It is directly affected by body fat at least. Fat is insulating (hence whales, seals, etc. having a thick fat layer) and definitely being on the larger size with a higher % of body fat makes someone feel warmer.

It's also directly affected by muscle mass, for a similar reason. Also body mass to body surface area does play a part from what I've read.

What's the relative impact of that vs clothing though?

I'd say far less than the layers of wool in a suit.

I work from home and don't do business suits. I've always kept the a/c on 26 because I don't like the shock that you get when moving even from 19 to 30. Looks like other people are finally noticing that...
