Identify the characteristics of a traditional house in a geographical region.
Clues for a Comfortable House.
The comfort of dwellings depend on their location and on their construction.
The roofs
good orientation
accessibility to water and food
Walls
Windows and wall openings
1- The functional and residential requirements of a house are first of all
determined by ________________________.
2- Giving a _______________________ to a building can help to control
the effects of sun, wind and rainfall.
3- ______________________ should have different inclinations if they are
in dry or rainy regions
4- ____________________________let natural light into the house, but
they do not help to retain heat inside the house.
5- _______________________can be made of different materials and
thicknesses.

countries, houses have ___________
and white washed walls.
The ______________ explain
the need to include water pipes that
collect the water in tanks. This has
proved to be essential during

The Climates in the Tropics.
The environment conditions in the tropics fall into 2 broad
categories that can be in sharp contrast; the impenetrable
rainforest versus the openness of the savannah.
The tropic Cancer

The
Equator
The tropic Capricorn
The sun is directly overhead on the 23

The Rainforest.
Complete using these words : little storms on the Equator bamboo
The warm, humid regions and tropical rainforests, monsoon regions and humid
savannahs are ________________. The rainforest is hot and humid with
__________ yearly differences. The regions in the Southern hemisphere have
_________ 120-140 days of the year. These conditions make life for people
difficult to tolerate. The vegetation is impenetrable with wet ground, men need
to clear the forest so as to build their settlements. The traditional materials for
building in these regions are timber, ___________ and grass or palm fibres.
Building in the Humid Tropics.
A home in the humid tropics
must be protected from heat,
strong solar radiation, high
levels of humidity, torrential
rainfall and floods.
Houses are mostly made of
____, bamboo and palm tree.
These materials are collected
and treated in the same
location or nearby. Traditional
buildings are open and have
well ventilated spaces to favour
dryness. They have a_______
made of leaves and fibres and
____________Their main floor
is elevated so as to avoid
humidity.

The savannah regions have two seasons. The climate can be either hot
and dry or warm and humid. These seasons vary from the Northern to
the Southern hemisphere. Deserts, semi-deserts, steppes and dry
savannahs are close _________________________. These regions are
characterized by high pressure level, strong solar radiation, dryness,
low precipitation, strong winds that cause sand storms and
___________ temperature differences between
night and day. The fertile ground is scarce and there is practically no
vegetation; mainly high grass and _________________________ with
individual trees. _________________ are traditional building materials.
They have good thermal insolating qualities. Timber is not easily
available and must often be transported from other regions.

Altitude: Another Climatic Factor.
Despite having a similar proximity to the Tropic, some regions share
very diverse climates in relatively small areas. Peru has regions that
provide us with an example of this dramatic climate diversity:

Climate Change and Global Warming.
What is the main cause of Global Warming?
Global warming comes as a result of the rapid increase of CO2 in the atmosphere.
What consequences can this phenomenon cause?
1- The Arctic Ocean could be ice free in summer by 2050. Global sea levels could rise by
more than 20 feet with the loss of shelf ice in Greenland and Antarctica, devastating coastal
areas worldwide.
2- The number of Category 4 and 5 hurricanes has almost doubled in the last 30 years. Heat
waves will be more frequent and more intense. Droughts and wildfires will occur more often.
Malaria has spread to higher altitudes in places like the Colombian Andes, 7,000 feet
above sea level.
Can you name one of the most recent climate disasters?
Torrential rains in China, hurricanes in Japan and in the Caribbean (Katrina. New Orleans)
ACTIVITY:
As a result of global warming, traditional constructions in ordinary locations may no longer
be suitable.
a- Decide a city where you would build a durable house. Locate it in a map.
b- What will it be like? Materials, structure, appearance
c- What sources of energy will it use?
