about clay construction

Building with clay has a long tradition in

Namibia and since the beginning of the CHP's

housing activities in 1991, the prestige of this

building material has continuously grown.Making use of modern construction

technologies, houses were optimized to be

long-lasting, affordable and attractive.

An important point is that even

unskilled people can contribute to thebuilding process through the

production of clay bricks, stamping

clay foundation or plastering.

Moreover, the

isolating qualities ofclay generate a cool

temperature insummer and keep

house owners warmin winter. Besides, the

ecological way of

building contributesto a healthy lifestyle.

In Otjiwarongo the

project has built morethan 200 clay houses

during the last six years,

but more than 1.300

other families are

searching for financial

assistance to build their

own clay house.

As people realize that

building with clay does not

only offer a cost-effective

alternative but also leadsto a more pleasant climate,

demand has become sooverwhelming that it

cannot be met by the CHP

alone.

Even when a clay

house cost only one

third of a cement

house, the mass of theNamibians can not

afford it without aloan.

about the Otji-Toilet

Saving Water with the Otji-Toilet

In Namibia water is a scarce resource, andlocal sources can't meet the growing demand.

The CHPs Dry Toilet System offers an

ecological and economical alternative - aninnovative system that helps saving water

and money.

How the Otji-Toilet Systemworks

A perforated container under the toilet pot

separates solid from liquid. The solid stays

in the container, while the liquid filtrades

into the ground.

After more or less six months the

container is filled with solid. With a long

steel hook the service contractor moves

it to the drying area of the tank. Thereit will dry out and reduce weight as well

as volumen. Meanwhile a second

A sun based ventilation system

at the back of the toiletprovides fresh air, which keeps

it dry and ensures an

odourless use. For inside

toilets we add a solar driven12 Volt fan for night

ventilation.

container is collecting the

droppings under the toilet pot.

After another six months, when

the second container is full, the

service contractor removes the

dry solid from the first

container, which can then beused for the next turn.

Professional contractors aredoing this maintenance twice a

year.

For public Otji-Toilets a urin basin

can be added to the toilet house

about the Clay House Project

The Overall Objective

The idea of building houses out of clayderives from the wish to overcome

the huge housing need in Namibia.Clay is available for free in many

places of Namibia.

How it startedA farmer near Otavi experimented to

build with clay. His positive results gave impulse to the founding of theNamibian Clay House Project Development Trust in 1991.

The first project tested soils throughout Namibia and then decided uponOtjiwarongo as an appropriate place to carry out applied research. This

town was chosen because of the quality of the clay, its central position

and furthermore, because of the support of its Municipality.

The first houses were built only from clay. In the 1995/ 1996 two family

houses and one office were built in Orwetoveni/ Otjiwarongo

In October 1996 Wiebke Volkmann, co-founder of the trust andcoordinator over the first 5 years, handed over the projects

management to the international NGO Grupo Sofonias. With Grupo

Sofonias the CHP became part of the Eco South Network for a

Sustainable Habitat (www.esocsur.org), which overall aim is to promote

environmentally and socially sound and sustainable development.

The production of other eco-

materials like Micro Concrete

Roofing Tiles and lime wasstarted. Experts from different

countries Latin Americas worked

for some time in Orwetoveni and

gave their input. Thanks to

different donors training courses

and several building phases could

be realized, like the building of a

kindergarten and the

construction of 20 clay houses in

Orwetoveni.

SODIEU and BMZ Projects

Since January 2002 the project came into a new

phase. The German NGO SODI (www.sodi.de)

and the European Community made funds free

for a 4 years project in Otjiwarongo, including

the building of 140 clay houses, the productionof micro concrete

roofing tiles (the

cool tiles are now

available in Otjiwarongo, Rundu and

Ongwediva) and the promoting of eco-

materials in Namibia.In 2006 started SODI an further building project funded

by the German Government (Federal Ministry for

Economic Cooperation and Development). The 3 years

project includes the building of clay houses for 100 poorfamilies in Otjiwarongo. Furthermore the Clay-House-

Project offers an building advice service to interested clay

house builder in Otjiwarongo. The project will be finishedin the year 2009.

Again the European Community is funding now the promotion and

building of 600 Otji-Toilets in Otjiwarongo and all over Nambia. The

project started in March 2008 and will be completed in 2011.

UNDP/SGP and other DonorsStarting with the year 2005 up to now UNDP/SGP has funded

several projects with the Clay-House-

Project. At first an building avisery

service was financed, afterwards 45 Otji-Show-Toilets and workshops to force the

massproduction of Otji-Toilets have been

funded by UNDP/SGD.German Embassy

In 2006 the building of new facilities, the Clay-House Seminar Centre,

was funded by the German Embassy.Solidarity GroupsOver the last years together 8 Kindergarten have been financed by

different German Solidarity Groups in Otjwarongo.

Cool tiles (Micro Concrete Roof tiles-MCR) are

made with cement, sand and water. Due to

vibration the concrete develops its strength,

thus the tiles can be produced relatively thinand are

lightweight. Aftervibration they are

put on a plastic mould which gives them theright shape. Cool tiles are corrosion resistant

(important for the coast), fire resistant, hail

resistant, water proof, light weight, and

function as sound and thermal insulators.

Furthermore, they

are produced

locally, which creates jobs, reduces transports

and makes them affordable.

To produce Cool Tiles a vibrating unit and

moulds are needed, both produced in Cuba

south south technology

transfer. As there is no

industrial plant

necessary for the

production of Cool tiles,it is the optimal

technology for small

scale businesses. InLatin America there are more than 700 small

entrepreneurs getting income out of tile

production. Theyproduce together around

3,000,000 m roof per

year.

The MCR technology has its roots in Latin America,

where it was developed in the 1970's under basic

participation of the Eco Sur/ South Network

(www.ecosur.org). Nowadays MCR Tiles are

produced in almost 30 countries around the globe,mostly in Latin America, but also in Africa

(Cameroon, Ghana, Zimbabwe, Namibia,

about Cool tiles


13/20

Cool Tiles are high quality roofing elements

The Clay House Project has introduced the name Cool Tiles under

which the tiles are marketed in Namibia. The name shall guarantee in

future the high quality of the MCR

tiles on the market. Only

workshops, which produce high

quality products under the qualitystandards of the Ecosur/Ecosouth

Network will get the permit fromthe Clay House Project to market

their tiles as Cool Tiles.

Cool tiles have been used

throughout Namibia for privatehouses (Windhoek, Henties Bay,

Otjiwarongo, Ongwediva),

community buildings

(Otjiwarongo) as well as on several farms and lodges.

Colors bring life in settlements

Cool tiles are available in gray

and in a variety of colors. They

can be colored with pigments

during the production: Pigments

are mixed in the concrete which

give a long lasting pastel color.

Another option is to paint the

tiles with cement stainer, an acid

based color which enters into thetiles surface.

For friends of real bright

colors there are varieties

of cement stainer on the

market.
