Exploring the Dynamic Aspect of Natural Air flow on Occupants Thermal Perception and Comfort

The main purpose of this paper is to review the effect of the dynamic aspect of natural air movement on occupants’ thermal comfort. Recent advanced investigations addressed the dynamic aspect of air movement in terms of turbulence intensity, probability distribution and power spectrum. This paper is not only about providing a thorough description and discussion on the underlying physical mechanisms of these factors, it is also about reviewing the effect of these parameters on occupants’ thermal sensation, perception and comfort under different thermal conditions.
