Designed by Chua Shi Hui (4) Kimmi Leclassroom is supposed to be a conducive environment for study and interaction, so that students can make full use of it to learn as much as they can. In Singapor

other countries, the weather may be too hot, causing the students to lose focus and concentration during lessons as the current classrooms gets heated up easily. He

need a better design for the classroom so that the students can learn in a better environment.

so that the

convection currents flowing

upwards can be released out

of the classroom into the

open air. This prevents the

classroom from heating up as

Heat Transfer Process(es):

Conduction, Convection,

Windows

The windows should be

double layered

so that heat cannot

pass into the classroom

through convection or

conduction. The windows

should be separate panes

so that they can be opened

for ventilation purposes. In

between the layers of

glass, there will be a

to prevent

conduction. Also, frames of

the windows will be shiny

to keep heat

from the sun outside and

the temperature in the

classroom to be steady.

Feature C - Walls

The wall should be white on the inner side of the classroom so that it can reflect the heat away, maintaining a steady

temperature. It also gives a conducive environment for the students as the white wall makes the classroom seem a little b

On the outer side of the wall, the wall should be white, shiny and smooth to prevent radiation. The wall will then be able

the heat away. The wall should also be made of cement as it is a poor conductor of heat. This can ensure a steady temper

The wall should also be a double layered wall such that the heat cannot pass into the classroom due to the layer of air bet

the two layers of wall. This will ensure a steady temperature. There is still the need for the cement wall as there might be

intersection points where the double layered wall cannot be used.

Feature E - Fans

The fans should be put at the top of the classroom for safety reasons such that the fans will not hit

anyone or damage anything. The fans can then blow the heat out through the opening at the top and

create artificial wind, making the students feel cooling. Hence, the fans help to ventilate the classroom

and maintain a steady temperature.

Through this project, we have learnt to apply our knowledge in real life situations, such as in the features of the classroom which we alw
