Selecting air speeds for cooling at sedentary and non-sedentary office activity levels

The air speeds personally chosen by test subjects in the 24 °C and 26 °C conditions differed little from the experiment's fixed air speeds. Subjects chose significantly greater air speeds in the 28 °C and 30 °C conditions. The elevated 1.4 metabolic rate slightly increased subjects' thermal sensation, but caused no significant difference in the air speeds they chose for sedentary activity. Personal control over air movement had no significant effect on comfort in the conditions tested.
