Writing Task 1 You should spend about 20 minutes on this task. The diagram below shows some design principles for an energy-efficient house and how they work in different climates. Summarize the information by selecting and reporting the main features and make comparisons where relevant. You should write at least 150 words.

The diagram demonstrates the design and infrastructure of an energy-efficient

house

in warm and cold

climates

. It

also

shows how

this

design redirects

heat

flows differently in these two

climates

.

Overall

, both dwellings have the same over-arching structure, resembling that of a typical

house

with a slanted roof, a skylight and an underground floor.

However

, their infrastructure exhibits some contrasting features. In colder

climates

, the

house

is designed to retain more

heat

.

Consequently

, it has a triple-glazed, open skylight that maximises the entry of warmth from the sun and the surroundings. It

also

has an insulated interior to ensure that the

heat

energy remains captured within the confines of the

house

. The underground floor in the dwelling for a cold climate serves to preserve the

heat

as well.

On the contrary

, the design for the

house

in warm

climates

aims to reflect the incoming

heat

in order to maintain coolness inside. For

this

purpose, the roof of the

house

is coated in a reflective covering. The insulation of the walls of the

house

retains the cold air trapped within the

house

in contrast

to that of the cold-climate

house

.

Additionally

, the underground floor is made to protect the inhabitants from the sun, extending the cooling effect during the scorching summers.
