The "clo" seems problematic as a unit. I know people who dress in hoodies in 100 degree weather and don't break a sweat. I know others who are sweating in shorts in the winter. I put out a lot more heat than my wife and yet I _feel_ cold a lot more than she does. Comfortable temperature is too subjective to get its own unit. It strikes me as something that was developed during that period of the early 1900s when they believed all of life could be reduced to a calculation.
- profstasiak 4y agopeople differ. Maybe you need more clo to be comfortable, but still the clo unit is valuable. Similarly you might need more calories than your wife, which doesn't make an unit of calories problematic.
- pard68 4y agoA calorie is not a subjective unit. A "clo" is by its definition. >one "clo" equals the thermal insulation required to keep a resting person (for instance, a couch potato) indefinitely comfortable at a temperature of 21° Celsius (70° Fahrenheit) This assumes we all produce the same output heat. We do not. Even at rest people output different amounts of heat. Normal skin temps range by almost 8 degrees Fahrenheit. Edit: Forgot to add "comfortable" is in the definition and comfort is always a subjective. I might be comfortable in my underwear at 70 degrees. And someone else (apparently) is comfortable in a three piece suit at 70.
- soperj 4y ago> almost 8 degrees Fahrenheit. 4.5C for those wondering.
- mrgoldenbrown 4y agoThe article acknowledges this: "The most significant factor influencing thermal comfort - even more important than air temperature and clothing - is body heat production" ... "The clo-values given for different indoor air temperatures are thus not more than guidelines - personal differences will occur."
