Yeah, regrettably, the American practice seems to be to overchill in the summer and overheat in the winter. This is also done in the home to the point that people will wear shorts and tshirt indoors in the winter and warmer in the summer (blankets while watching TV for example). Also office buildings suffer from the same problem. Women usually complain the most about it being too cold (men are more likely to wear suits and generate more great I believe).
