Abstract
Single-sided ventilated spaces are a common type of spaces, which have openings in only a single side, which is responsible for delivering natural ventilation, unfortunately in many buildings, these openings do not deliver the required ventilation into building spaces, despite the Availability of desired prevailing wind, this paper concerns the role of traditional wooden lattice windows "Mashrabiya", in delivering natural ventilation in single-sided ventilated spaces, a computational fluid dynamics CFD simulations program ANSYS was used to investigate air movement behavior, through several unique types of 3D lattice models, to figure out the impact of lattice windows in delivering natural ventilation, results show that some types of Lattice windows with multiple rounded surfaces, create a pressure difference, because of some surfaces of lattice window located upward wind, and some others located leeward, which creates a pressure difference that leads air to move between highpressure zones to low-pressure zones, and delivers a natural ventilation in single-sided spaces, which could be considered in building design, in order to deliver natural ventilation in single-sided ventilated spaces.
