The purpose of this research paper aims to conduct a thorough study on the implementation

of vernacular Malay architecture in 8D House. It also aims to investigate how these design

strategies help to reduce solar heat gain and achieve thermal comfort in this building. Due to

the rise of commercial developments in Bukit Damansara that contributes to the increase of

thermal heat, the 8D House was designed by architect Dr Tan Loke Mun to curb this climatic

issue to improve the thermal comfort for the users in the building. To assist the validation of

research, literature reviews based on various sources such as books and online research on the

researched building and thermal comfort were conducted to complete this case study paper.

The vernacular Malay architecture is greatly influenced by climate and weather and it is the

most appropriate for thermal comfort in Malaysia’s climate. 8D House is efficiently designed

to suit this local climatic requirements using raw local materials such as masonry, concrete

and timber. 8D House has a perfect rectangular building form which makes it easier to lose

internal heat to the outside. The building is also orientated with the long façades are arranged

to face the direction of incoming prevailing wind. Landscaping such as vegetation and water

features are carefully placed in relation to sun paths and prevailing winds. Vegetation helps

shade the north-east façade, preventing direct solar radiation. Hardscape is shaded from direct

solar radiation while softscape is used to absorb heat and reduce ground temperature. 8D

house uses large insulated overhanging canopy roof to control the penetration of solar

radiation. The roof tends to be under lighted to give a psychological effect of coolness as

strong light is often mentally associated with heat. Its roof was constructed with lightweight

metal decking in light grey colour and has an air gap that act as a barrier to heat flow. This

bungalow also controls glare from the open sky and surroundings by using metal louvered

sun screens to wrap the entire mass of the living spaces. Louvers are also extended from the

façade to allow air ventilation and different lengths vary on different sides of the façade,

where facades that face more solar radiation have longer louvers. Hence, it has come to a

conclusion that the application of these design strategies in reference to vernacular

architecture does reduce solar heat gain and reduce thermal comfort in 8D House.
