This book introduces new indices catered for elevated air movement for systematic ventilation performance evaluations regarding thermal comfort, indoor air quality, and energy efficiency. Elevated air movement of ventilation system is polarized for energy-efficient creation of thermally comfortable and healthy indoor environments as a sustainable solution to climate change and respiratory diseases. While ventilation performance indices are indispensable for the proper design and operation of ventilation system, elevated air movement challenges the traditional ventilation performance indices designed for low air movement. The cooling effect of air movement on thermal comfort and energy efficiency and the contaminant dilution and removal effects of ventilation on airborne infection risk control are particularly highlighted. The book is intended for undergraduate and graduate students, researchers, and engineers who are interested in cutting-edge technologies for sustainable and healthy built environments.
