ABSTRACT
In the modern set up, a lot of technologies have been used to improve on the effects of heat on
the comfort of the structures. These technologies include modification of the natural means of
heat transfer. The natural means of heat transfer includes convection, radiation and
conduction.These modifications are tied to the properties of the materials used for building. . The
passive cooling system does not completely eliminate the use of other mechanical means like fan
but it assist in the improvement of the installed structures.
Most of the studies have shown that enhanced means of cooling is through the use of hybrid
system. Roof design with sustainability normally goes beyond the cost but also focuses on the
efficiency of energy consumption. The extent to which the roof affects the environment should
be put into consideration for proper design. These factors will in turn affect the maintenance and
requirements of renewal in the life of the structure.

INTRODUCTION
Anybody who has lived on the uppermost floor of any building in the Australia or other parts of
the world with similar climate may have experienced discomfort that results from higher
temperatures especially during the summer seasons. Majority of the buildings in Australia are
built using concrete with flat configurations of tar roofings.These surfaces normally absorb the
incident radiations that are directed to the building. The ceiling that is hot will continue to heat
the available space hence making these places unbearably hot during the day as well as night in
the entire season of winter. ( Tong et al 2014).
In the recent years, these places have undergone improved level of urbanization especially in the
developed countries like Singapore,Indonasia and Malaysia. This increased process of
urbanization has been as a result of the increased population in those areas. The intensity of the
urban heat island commonly known as UHI has also increased. This affect is characterized by the
increase in the consumption of the energy especially the issue of cooling and this is just a
primary concern.
OBJECTIVES
 To highlight the passive cooling strategies and products that are normally used to prevent
the heat gain particularly inside the buildings in Australia and other parts of the world.
