There is now clear scientific and political agreement in the
world that global warming is happening and that CO2 and
others greenhouse gas (GHG) in the atmosphere are
responsible of;
Cameroon has committed to stabilise its carbon emissions
and also to reduce poverty, but no clear targets have been
established
However develop country such as UK has committed to
reduce its carbon emission and has published 2008 UK
Climate Change Act , which sets new targets reduction
as following...

Global population is 50% urban, about 3 billion,
but one billion people, are living in slums
Due to rising population and Climate changerefugees from flood and drought, rapid
urbanisation is taking place
Slum population will reach 1.4 billion in 2020
In Cameroon , urbanisation is projected to be
more than 50% in 2010 from 2007 level. And
low cost homes grow as the cities grow

ECO-HOUSE
EcoHouse, or Low
energy house , or green
building are terms
frequently used to define
a house, whose energy
consumption and CO2emission are lower than
for a similar conventional
house.

The aim is to optimise the use of direct natural
sunlight, to achieve thermal comfort with

Current Low cost housing in Cameroon :
Hollow cement block for wall and concreteflooring , which have reasonable thermal capacity
Alternative material such as earth brick have
much high thermal capacities but have been
rejected by communities in earlier projects, as
they are perceived to be inferior material
ECOHOUSE (3/4)(Building envelop measures)
Building envelops materials are made with
appropriate building materials, such as material
with high thermal mass, which are able to store
heat/cool during the day and release slowly
when needed

ECOHOUSE (4/4)(Building services measures)
In Cameroon, the urban poor
households rely on:
- biomass for cooking;- kerosene and candles for
lighting;
-Illegal electricity connection;
-Inadequate water distributionsystem
Access to modern energy system
is still beyond their reach.

Need of National Policies, norms and
standards for energy efficiency and
Renewable energy in building In Cameroon design of most modern
buildings and low cost homes are not
adapted to the local climate, resulting inunnecessary energy needed for lighting,
cooling or heating
The preference building material such asaluminium sheet with poor thermal
characteristic, results to major energy
wasted to create in-door comfort.

MDGs and Sustainable Development goals in Cameroon are
unlikely to be achieve without intensive R&D activities to
address low energy homes requirements. Emphasis shouldbe given to the following issues:
1. Passive building systems
2. Energy and environmental conscious design of low
cost homes should not be seen as a developed countriesbusiness, but research needed to be done to find an
appropriate approach for eco-house in Cameroon and then
integrate the results into Building Regulations
CONCLUSION (1/2)

Most cities in Cameroon have untapped renewable
energy potentials that could address poor households
energy shortages. however Particular R&D on use of
renewable energy technologies in buildings, as opposedto conventional energy. R&D activity to address
the following aspects of Eco-house is needed:
Energy efficiency
Energy producer (PV integrated);
Affordability;
Climatic conditions (smart); and
Human thermal comfort
