What is the primary function of natural ventilation?

• To increase humidity

• Process of supplying and removing air through a space by natural means

• To block sunlight

• To create a high-pressure system

What type of air movement is characterized by smooth flow?

• Turbulence

• Eddy

• Laminar

• Separated

What is the effect of a cross ventilation in a room?

• Winds have no effect and does not move

• Winds blow towards the room with highest velocity

• Winds spiral around the room and stuck

• Winds flow from one openings to another creating seamless flow

What is the stack effect?

• Airflow caused by wind from the outside that flow towards the inside

• Pressure difference between the outside air and the air inside the building caused by differences in temperature

• Air moving horizontally then decided to move vertically to avoid clashing of structure

• Air being trapped inside and do not know where to go but the only option is up

What is the Venturi effect?

• Air moving in a circular motion when there is no wind

• Air being filtered through openings at wall and facade

• The increase or decrease in flow velocity, depending on the pressure difference

• Air rising due to heat, so hot so they go up

Which of the following is a feature of traditional Malay architecture?

• Utilizes modern contemporary materials for aesthetic appeal

• Incorporates natural lighting and natural ventilation for thermal comfort

• Has Ergonomics and Anthropometry layout to function well

• Built on stilts to allow parking of cars underneath

How does deep overhang influences the flow of air?

• Type of furniture located at the verandah reduces wind flow

• Height of the building ensure more wind coming in

• Color of the wall and roof can reflect the heat gain on the roof

• Buffer area to allow transfer of heat through flow of air

What is the purpose of volumetric spaces in traditional Malay architecture?

• To enhance privacy

• To increase sunlight exposure

• To allow multiple tier of wind flow

• To create storage areas

Ady is designing a new studio space for architectural students in Puncak Alam and is considering various architectural features to avoid the dependency on air conditioning. What should he consider as the best option?

• To provide deep overhang for extra shade and reduce heat

• To increase structural integrity and allocate more columns in the layout

• Install large fixed windows for extra sunlight and increase transparency and visibility

• open layout with several opening to allow cross ventilation throughout the space
