The Performance Of Wind
Wing-Wall On Air Velocity For High-Rise
Residential Building In Malaysia.
Masters thesis, Universiti Sains Malaysia.
Abstract
Global warming has sparked many to seek environmental friendly ways to
reduce the impact of climate change especially in generating energy. The problem is as
world population grows, demand and consumption of electricity increases. Population
increase in South East Asian countries has compelled Malaysia, Singapore and Thailand
to go for high rise buildings due to the limited land mass. Many did not realize that as
living in high-rise buildings the endowment given by nature that the higher the
buildings the faster the air velocity and this endowment was not taken into consideration
during design process to tap the availability of natural ventilation. Present buildings are
design using the conventional way of cooling the interior and that is by air-conditioning
thereby increasing energy aggravated by the population increase. Several studies show
that different architectural elements and techniques are related in improving the
efficiency of ventilation systems in natural ventilated high-rise building. One of the
latest methods in the field of construction is the use of wind wing-wall in high-rise
building. Wind wing-wall is a solid panel, or a long standing wall alongside windows,
balcony or other openings that can be used to redirect or guide air velocity into the
building. Applying wind wing-walls is a method that encourages the natural wind
ventilation into the building. Anyhow, limited studies have been carried out on the
application of wind wing-walls by their effectiveness on overall indoor ventilation.
Since Malaysia is mostly surrounded by seas and populations are mostly concentrated in the coastal area, the natural ventilation can be tapped for practical uses but information
for empirical air velocity pattern seemed limited.
