SUSTAIN

UNDERSTANDING
In olden days, sowing the seeds and then planting them was a regular practice of
everyone. It is because of their idea we are able to enjoy all the resources very
well.
PERCEPTIONONSUSTAINING
SOMETHING
If we are cutting a tree to use its wood and other parts then we should plant at least
one or more than one sapling at the same time, nourish, protect and hand it over to
next generation
We are using the resource but then making way for the future generations to use the
resources as well.

DEFINITION
The definition for sustainable development is the one given by World Commission
on Environment and Development (Brundtland Commission) which runs as the
"development that meets the needs of the present without
compromising the ability of future generations to meet their own
needs.”

SUSTAINABLE DEVELOPMENT
Sustainable development ties together concern for the carrying
capacity of natural systems with the social, political, and
economic challenges faced by humanity.
It contains within it two key concepts:
• The concept of 'needs', in particular, the essential needs of the world's
poor, to which overriding priority should be given; and
• The idea of limitations imposed by the state of technology and social
organization on the environment's ability to meet present and future
needs.

Two Vital Actions
Available Resources
Stop exploiting the ones that’s going to be extinct
Opt renewable resources
Ensure Consumption and Production patterns
Waste
Reduce waste Self – manage waste
reducing the waste generation managing the generated waste
• don’t be lavish
• minimising spills or leaks

SUSTAINABLE APPROACHES
ALTERNATIVE RESOURCES
• Solar Energy: completely free and is available in limitless supply of energy
that is environmentally and financially effective and help reduce pollution
• Wind Energy: the use of windmills at suitable location. This kind of energy is
meant to service more than just the individual.
MINIMISING WASTE OF EXISTING RESOURCES
• Efficient Water Fixtures: Encouraging the installation of efficient shower
heads, toilets and other water appliances can conserve one of Earth’s most
precious resources: water. Examples: dual-flush and composting toilets.
SUSTAINABLEAPPROACH

SUSTAINABLE APPROACHES
VIRGIN SOIL
• Crop Rotation: the successive planting of different crops on the same land to
improve soil fertility and help control insects and diseases. It is chemical-free
and maximizes the growth potential of land.
URBAN SOCIAL
• Green Space: Green spaces include parks and other areas where plants and
wildlife are encouraged to thrive are public great opportunities to outdoor
recreation in dense, urban areas. Advantages of green spaces include helping
regulate air quality and climate, reducing energy consumption by countering the
warming effects of paved surfaces, recharging groundwater supplies and
protecting lakes and streams from polluted runoff.

SUSTAINABLE APPROACH IN ARCHITECTURE
Sustainability
not a concept but a function
• Sustainable architecture is architecture that seeks to minimize the
negative environmental impact of buildings by efficiency and
moderation in the use of materials, energy, and development space
and the ecosystem at large.
• Sustainable architecture uses a conscious approach to energy and
ecological conservation in the design of the built environment.

My feeling as an architect is that you are not after all trying to put up a
monument which will be remarked as a ‘Laurie Baker Building’ but
Mohan Singh’s house where he can live happily with his family.

WORKING LIFE
AS AN ARCHITECT
AND A HUMANIST

PRINCIPLES OF LAURIE BAKER
• Only accept a reasonable brief
• Discourage extravagance and snobbery
• Always study your site and see potential relating to the soil, drainage, power,
fuel etc.
• You yourself get accurate site details and in-situ facts
• Every building should be unique; no two families are alike, so why should
their habitation be alike?
• Study and know local materials, cost, building techniques and construction
• Study the energy used in the production of materials and transport
• Don’t rob national resources; don’t use them extravagantly or unnecessarily
• Be honest in design, materials, construction, costs and your own mistakes
• Avoid opulance and showing-off by using currently fashionable gimmicks
• Get your conscience out of deep-freeze, and use it
• Look closely at your prejudices and question them
• Have faith in your convictions and have the courage to stick to them

DESIGN PRINCIPLES OF LAURIE BAKER
LAURIE BAKERS architectural principles of
• cost-effectiveness,
• use of locally available materials,
• respect for nature,
• avoidance of energy intensive materials and
• wastage minimization
to create low-cost, beautiful, high quality buildings which long pre-empted
modern concepts such as eco-friendliness and sustainable architecture.

DESIGN APPROACH
• Use Arches rather than lintels
• Many varieties of arches flat, segmental, pointed rounded, corbelled, and so on.
• All arch methods are equally suitable for mud wall construction
• Remember to give adequate width of support walls to deal with the arch thrust.
• Frame work, templates, arch frames must be removed immediately the arch is
completed (to allow for compression as the mortar dries and shrinks)
WINDOW OPENING

DESIGN APPROACH
• In many instances frameless doors and windows are acceptable and reduce
both quantity of timber, labour and costs
• Board and batten type shutters are less costly, use less labour and less timber
than panelled shutters.
• Glass is often not necessary. Only use when it has a useful purpose and is
essential.
• Glass manufacture is Energy intensive.
• It is extravagant or unnecessary use
DOORS & WINDOWS

DESIGN APPROACH
• Alternative slab in-situ systems include filler
slabs (void formers) which reduce
materials and cost by about 30%, but
shuttering is costly.
• Again, local balancing and comparing of
overall costs, transport, labour, and energy
used etc, have to be made before a choice
is made and it will vary from place to place.
FILLER SLABS

DESIGN APPROACH
JAALI WALL
Jaali Wall is a better substitute for a
glass window. It lets in general
subdued light. It also deals with
ventilation but prevents driving rain
from entering. You can look from
the inside to the outside but from
the outside you cannot see inside.
It is secure and thieves or animals
cannot enter.
BRICKS & BONDING
•Use bricks in districts where it is made and is
plentiful. 25% of bricks, mortar, cost etc can be
saved by using the Rat trap Bond. This can also
usually
•4.5" walls are stable and strong if corrugated
or buttressed.
•9" walls are usually capable of being load
bearing up to three storey height

THE HAMLET, Trivandrum, Kerala
Key features of his house are:
• All the walls are made of mud bricks.
• Timber salvaged from an old boat
jetty
• One of the other signature elements
of his design includes the use of
circular walls, which use far less brick
than rectangular walls.
• In addition, when he does use
concrete for a roof, he embeds
chipped or broken terracotta roofing
tiles into the mixture.
THEHAMLET

Key features of his house are:
• These tiles, which normally would be
thrown away, contribute to the strength of
the roof, allow less of the expensive
concrete to be used, and reduce the
structural load of the building.
• He used broken tiles for the outer paved
area of his garden.
• The living room, An integration of new
building and salvaged timber from
traditional buildings that were being
demolished.
• Baker's innovative use of discarded
bottles, inset in the walls giving a very
good effect of light and creating an
illusion of stained glass.

FIRST FLOOR
GROUND FLOOR

• Steps directly cut in rock
• The wall is decorated from broken pottery, pens, glass
• A calling bell for visitors to announce their presence
• Never cut trees instead adapted his design accordingly
• Use of natural light
THEHAMLET

• Gables for proper air circulation & ventilation
• Grill made of bits & pieces
• Louvered window
• Stained glass effect
