Comfort Factors
  • The human body loses heat primarily through convection, radiation and evaporation.  Air motion, relative humidity and the temperature of the air and of surfaces around a person play large roles in human comfort.

  • Clothing and activity levels also significantly affect people’s perceptions of comfort.  People working at high activity levels will accept conditions that sedentary people will not.  Because of individual differences (such as different clothing, activity levels, and personal tolerance), people will not always agree that 70 °F is a comfortable temperature.

  • All of these factors need to be considered when analyzing complaints about comfort in a building. Air temperature is only one piece of the puzzle.
