Air movement can be characterized by its mean velocity, turbulent intensity, power spectra, velocity distribution probability, etc. Based on a field test, it was found that the characteristic of an artificial air movement is different from that of natural wind. In order to simulate the characteristic of natural wind, two air supply devices were investigated. Furthermore, the acceptability of the subjects exposed to the simulated natural wind is higher than that of subjects exposed to artificial air movement. Through the subjective assessment, the preferred mean air velocities at different ambient and supply air temperatures are presented. Finally, a conditioning mode using fluctuated air movement in warm climates, and a prediction of energy savings are given.
