ABSTRACT:
This research presents the adoption of wind tunnel modeling to study the environmental wind profile to enhance the performance of natural ventilation on New University Town @ Warren. Wind tunnel experiments were conducted with the use of scaled model to determine the natural ventilation performance in terms of wind velocity. The regions with low wind velocity were identified and examined.

The study also explored the impact of variations of the design parameters, which classified into four divisions, namely, openings of buildings, height of buildings, orientation of greenery and spacing between presences of greenery on environmental wind conditions. A total of eleven stages of experiments were performed in this study. The results indicated that the values of wind velocity were significantly affected by the variation of design parameters. Openings and heights of buildings in relation to prevailing wind direction can notably enhance the wind velocity. The presence of greenery in the prevailing wind direction influences the magnitude of wind velocity by producing shielding effect, which can be proven to serve as an effective windbreak. Furthermore, tree spacing played a part in modifying the wind velocity. As trees spacing increased, the values of wind velocity increased.
