When I was little I always wondered why buildings had to be kept so cold. It became clear while having to wear a tie working in Hong Kong and China. As far as I can tell, a huge sum of money is wasted and pollution created because of society's need for to be men to be in suits. There would be incredible savings on power and discomfort if stringent dress codes could be abolished. The endless night of western business attire's imperium has caused me much discomfort and loss in productivity during summers. Some kind of alternative or, at least, a downgrading to just collar shirt and slacks would be nice. I think it is infantile for society to be hung up on this when brownouts occur all the time, air-conditioners raise the general level of heat in the city, and power-costs are skyrocketing. Living in our air-conditioned society also makes me sniffle all summer, have sweat around my neck even with the AC, sweat on the way to work even without a tie on, business casual. Professionalism, fine, but I find myself more productive when I am comfortable. I know people here won't appreciate my comments, but I regret that the West was able to impose it's restrictive and uncomfortable sartorial standards on places so much hotter than Europe.
I know that during the summer the temperature in Tokyo is at least 5-10 degrees higher than the surrounding areas due to the aircons blowing all the hot air outside. Literally every room of every urban building has its own air conditioning unit. So on a hot day, Tokyoites vent the combined temperatures of 35,000,000 people out into the streets.
