范文

The diagrams show how house designs differ according to climate.

The most noticeable difference between houses designed for cool and warm

climates is in the shape of the roof. The designs also differ with regard to the

windows and the use of insulation.

We can see that the cool climate house has a high-angled roof, which allows

sunlight to enter through the window. By contrast, the roof of the warm climate

house has a peak in the middle and roof overhangs to shade the windows.

Insulation and thermal building materials are used in cool climates to reduce

heat loss, whereas insulation and reflective materials are used to keep the heat

out in warm climates.

Finally, the cool climate house has one window which faces the direction of

the sun, while the warm climate house has windows on two sides which are shaded

from the sun. By opening the two windows at night, the house designed for warm

climates can be ventilated.
