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

Subjects were tested under a set of air speed setpoints as might be used in automated control of ceiling fans. At lower temperatures the fan speeds were slightly higher than needed for thermal neutrality, to account for occasional non-sedentary metabolic rates associated with getting up, standing, or moving about. At higher temperatures the air speed supplied was conservative, to minimize mechanical wind disruption, while allowing thermal...
