The following weblog shows a range of prices for
replacement housing in the poorest section of India.
Also included is webpage citations for design criteria
and local indigenous materials.

This collection asks the question: how much Palace For

range in prices for cyclone-replacement housing

In non-PV-Breeder situtations, this total is
one-twentyfifth of the retail US prices for PV panels

Low cost housing for Orissa’s cyclone hit areas
Christoph Luethi,

Development Alternatives (DA) in collaboration with
CARE India is currently implementing a rehabilitation
project for 1400 households in the areas worst hit by
cyclone in the state of Orissa.

The cyclone that hit Orissa on 29th.October 1999, has
left over 10,000 people dead and damaged 1.9 million
houses and 18,000 schools and colleges in 12 districts
of the eastern Indian state. Orissa is the second
poorest state in India with an average GNP of $ 38 per

The disaster relief operation that got underway at the
end of 1999 also was to include the rebuilding of
houses for the most destitute and hardest hit by the
cyclone. In a community managed process involving
intermediary organisations like DA and local
implementing NGOs like AKSS, CARE is carrying out a
unique rebuilding effort which will deliver large
numbers of cyclone-resistant core houses using
cost-effective appropriate building materials.

Core funding for the project comes from the British
OFDA and DEC agencies and beneficiaries are expected
to contribute sweat equity during the house
construction process. The project is expected to
rebuild 1400 homes, train 1500 village masons and
expose over 30,000 households to the new building
The table below gives a breakdown of the costs
involved for one house, including labour and material
inputs. At Rs.29,000 / $632.- (Rs.2420 per m2) the
core house is a good low-cost solution that provides
protection from future cyclones. This cost is expected
to come down further, once all building banks will be
working at full capacity. Another added advantage of
the building materials used: construction time is
brought down to only 7 days (excluding foundation

Total costs for 1 housing unit as per the 1st set of
20 constructed houses in $632. Cost is expected to
reduce as the delivery is streamlined. ...


The ACT members plan to build 1,500 such cyclone safe
houses along with hundreds of traditional homes. The
villagers build the houses themselves but LWS-India,
UELCI or CASA provide essential building materials
along with food for the villagers while they build the

Box 1.4 Shelters save lives and livelihoods

On an October night in 1999, India's worst disaster in
living memory engulfed the villagers of Kurantatuth in
Orissa state. Windspeeds reached 300 kilometres an
hour. Tidal waves seven metres high crashed inland.
Whole villages vanished.

As warnings reached the local Red Cross office,
volunteers went door to door urging people to
evacuate. When visibility dropped to less than five
metres, the rescue team tied a rope to a tree and ran
it to the Red Cross cyclone shelter.

Before the tidal wave engulfed the village, over 2,000
people were squeezed into a structure meant for no
more than 1,500. After the storm subsided, villagers
looked out and saw nothing but water, and hundreds of
floating corpses, among them the neighbours who had
chosen to stay at home. Virtually nothing remained of
Kurantatuth but the cyclone shelter.

Similar stories could be heard from Orissa's 22 other
cyclone shelters, all built by the Indian Red Cross
with German government support. According to the
Orissa government they saved 40,000 people. Based on
the shelter project's budget, that works out at around
US$ 80 per life saved.

But numbers are just part of the equation. Between
cyclones, Red Cross shelters provide a focal point for
rural disaster preparedness, education, first-aid
training and self-help savings groups run by local
women – all inseparable elements of living with, and
recovering from disasters.

The cyclone affected are a covers most of the coastal
belt of Orissa where the devastation has occurred
because of three main causes:

(1) Very high wind velocity of the order of 250
km/hour (70 m/s) causing tremendous pressures and
suctions on the building roof and walls resulting in
their destruction;
(2) The storm surge upto 7.5 m height coming from the
sea as a result of the high wind velocities, the water
first flowing from the sea towards the land as a wall
of water and then flowing out from the land to the sea
taking away everything that came in its path; and
(3) Very heavy continuous rain producing flood
conditions in the flat coastal plains, particularly in
the basins of River. Baitarni and Budhabalang

In the reconstruction of houses all these parameters
must be accounted for if the reconstructed buildings
have to survive the cyclones in future.

Safety from Water

(a) To save the population, their cattle and household
possessions, the first priority will be to protect the
buildings from the onslaught of water, whether from
the sea or from the flood due to heavy rains. This
could be done by raising the ground floor of the
buildings in one of the following three ways:

(i) to choose the site on high grounds above the
highest water level that could be reached during flood
or during high storm surge and tide;
(ii) to construct the buildings on raised mounds so
that their plinth level is above the highest water
level; or,
(iii) to construct the buildings on stilts, again
keeping the floor level above the highest water level.

The safest solution from this point of view will be to
raise the base level of the whole village.


The design wind pressure at height z above ground
level on a surface normal to the wind stream is given
Pz = 0.0006Vz2

Where Vz = design wind velocity, m/s
Pz = design wind pressure, kN/m2

The value of wind pressure actually to be considered
on various elements on aerodynamics of flow around
buildings the windward vertical faces being subjected
to pressure, the leeward and lateral faces getting
suction effects, and the sloping roofs getting
pressures of suction effetcs depending on the slope.
The projecting window shades, roof projections at eave
levels are subjected to uplift pressures several times
the intensity of Pz. These factors play an important
role in determining the vulnerability of given
building types in given wind speed zone. For example.
Fig. 4 shows the various cladding areas of building,
which will have different pressure coefficients.

Figure 5 and 6 show typical effects of openings in the
walls for a given angle of attack of wind a indicated;
only one large opening in a wall cause very large
internal pressure say +0.7pz which combined with
external suctions will increase the wind effects on
cladding and their connections immensely. A building
with all windows and doors locked. will have zero or
very small internal suctions or pressure <0.20 pz. If
a room has openings distributed in all walls or at
least in opposite walls and the overall porosity is
less than 5%, the passage of air will cause only low
internal pressure say only 0.2pz. Effects of wind
uplift on roof projections can also be seen in Fig. 5
and 6. For a design pressures will be 1.5kN/m2 and
3.65kN/m2 respectively. The design pressures could be
obtained by multiplying with the coefficient as given
in Fig.5 and 6 for the specimen cases shown. For other
dimensions of length, width and height and direction
of wind, reference may be made to I.S.:875 Part

Orissa's Unnatural Disaster
UK - In the November '99 New Scientist, journalist
Fred Pearce, environmentalist Vandana Shiva, and
several coastal geographers attributed much of the
death and devastation from India's October 1999
supercyclone to the destruction of India's coastal
mangrove forests. Orissa's mangroves were cleared to
make way for shrimp farms. India has lost more than
half its mangrove forests in the past 40 years. The
cyclone ripped the coastal state with
300-kilometer-per-hour winds. A tidal surge and
torrential rains flooded up to 13 kilometers inland
with five feet of water. Poor communities 50
kilometers from the coast were washed away. About
10,000 people died, and 10 million were left homeless.
"In the past," says Tom Spencer of the Cambridge
University Coastal Research Unit, "the mangroves would
have dissipated the incoming wave energy." In addition
to providing habitat and fish nurseries, mangroves
trap sediment in their roots, creating shallow
shorelines that slow waves, while their leafy canopies
shelter the land from wind.
