“How would you like to design and
build a sustainable school in Uganda”?
Not the sort
of question that you expect to be asked at an Awards ceremony; but then the
2Degrees Awards are not your run of the mill event! The person asking the question was Alison
Hall of Seeds for Development and Pop-Up Foundation. She and Paul Clarke were very happy because
they had just picked up their awards for Solution of the Year; I on the other
hand was not; as I had not!

Beautiful traditional homes
built from mud, thatch
and small diameter timber |
So we
started working with Alison and Paul to design the school to be built on a site
in Arugudi Village, Northern Uganda. From the
first discussions it became clear that there was a powerful meeting of minds
about how the school should be conceived.
We wanted collectively to create an enduring, local solution that the
community could build, maintain and run, using locally sourced and easily
available materials and technology. We
wanted to develop and improve upon the existing vernacular architecture,
breaking the colonial tradition of breeze block and wriggle tin that dominates most
local school design. We were also keen
to avoid too much architecture and wanted to strive to find simple easy and
efficient solutions to problems, so that we could provide an adoptable
precedent that could be applied by other communities throughout the
region.
It quickly
became apparent that one of the biggest challenges would be around water and
sanitation. It has long been recognised
that female education is the key to unlocking development, yet currently most
girls leave school when they reach puberty due to a lack of basic sanitation. One of the first actions in making the school
will be the sinking of a borehole to provide a supply of water for drinking and
personal hygiene.
Human waste is
a major health hazard, so we have developed the design of the school around an anaerobic
digester that will process this material, from hazardous waste into a series of
useful nutrients. Solids and liquids will
be turned into fertiliser, used to grow crops that will provide lunch for
children. The methane gas from the
process will be collected and used to cook lunch, removing the need for timber
or charcoal for cooking.
The school
buildings will all be built by the community and their design has been heavily
influenced by the local vernacular tradition of simple circular huts, with
“adobe” earth walls and conical thatched roofs.
We believe that it is essential that local, freely available materials
are used, so that the environmental footprint of the development is minimal,
material costs are virtually eliminated and the skills and knowledge of local
people are valued and developed.
However, this
philosophical approach presented a significant challenge, since during the recent
armed conflict many people were injured or killed when the thatched roofs of
their homes were set on fire with them in them!
There is now strong resistance to thatch and we are exploring other alternatives,
including exploring the use of fast growing bamboo to form both the roof
structure and make bamboo roof tiles, due to its inherent fire resistance.

The conceptual layout of the school is less a plan,
more an "aunt Sally" to be challenged, questioned and adapted
by the farming community who we will help to build their own school |
To help
simplify and speed up the adobe wall construction we are developing a simple
hand press that will produce regular shaped and sized mud bricks that can
either be dried in the sun or using a parabolic solar oven, that can also be
used to cook food once construction is complete.
The
classrooms are hexagonal spaces capable of accommodating 50 children each,
arranged in clusters of five to allow one teacher to oversee up to 250 children
when necessary. The space enclosed by
the classroom cluster will be shaded by a tree to create a cool external shared
amenity space, with large over sailing roofs reducing solar gains and providing
shelter from monsoon rains. Light will
be provided within the classrooms by plastic water bottle rooflights that
refract natural light through water to produce the equivalent of 50W light
bulb.
The school
site will also include a demonstration home where the community will come to
learn about how they can reduce their impact through the adoption of new
technologies like solar stoves, improve sanitation by installing simple tip
taps so that they can easily wash their hands and learn to make and install
water bottle rooflights.
So after
nine months of research and development I shall be leaving for Uganda on
Sunday. I have had my jabs, started
taking my malaria meds and am feeling both nervous and excited. It will be my first visit to Africa and I am
sure that I will learn a lot in the week that I am there. One thing is certain, the discipline of
designing using local materials and labour will certainly provide valuable
learning that we will apply to projects at home. Just imagine what our economy and buildings
would be like if we could only use locally available labour, materials and
technologies?
