TRADITIONAL HOUSE

Indian vernacular architecture
Is the informal, functional architecture of structures, often in rural areas, of India,
built of local materials and designed to meet the needs of the local people.
The builders of these structures are unschooled in formal architectural design and their work reflects the rich diversity of India's climate,
locally available building materials, and the intricate variations in local social customs and craftsmanship.
It has been estimated that worldwide close to 90% of all building is vernacular, meaning that it is for daily use for ordinary, local people and built by local craftsmen.

Introduction
SIDE EFFECTS ARE
All these efforts are straining the limits of the Earth’s “carrying capacity”— its ability to provide the resources required to sustain life while retaining the capacity to regenerate and remain viable.

Contributing to GHGs
Buildings are by far the greatest producers of harmful gases such as CO2 and this 'eco-footprint' would increase with the large population growth predicted to occur by 2035 and the industrialization of the developing world.

SUSTAINABLE DEVELOPMENT
Development that meets the needs of the present without compromising the ability of future generations to meet their own needs
- The Brundtland Commission,1987

Sustainability and the Construction Industry
'Sustainability‘ a central concern - with rising populations and economic development are threatening the degradation of the earth's resources.
The construction, maintenance and use of buildings impacts substantially on our environment and is currently contributing significantly to irreversible changes in the world's climate, atmosphere and ecosystem.

Towards Sustainable Development…
Energy
Reducing energy consumption, being more energy efficient and using renewable energy and 'alternative technology'.

Materials
Choosing, using, re-using and recycling materials during design, manufacture, construction and maintenance to reduce resource requirements.

Waste
Producing less waste and recycling more
Pollution
Producing less toxicity, water, noise and spatial pollution.

Working Principles

Materials
Life-Cycle Assessment,
Eco-Labelling and
Embodied Energy Audits
Helpful for choosing materials and assess the balance between short-term costs and long-term environmental, social and financial benefits.

Embodied Energy
‘Embodied' energy - every brick has used energy at every stage in its production and use.

Choosing and Using Materials Sustainable way
Consideration while re-evaluating the way materials are used in construction:
Material Reserves assessment and sustainable use
Reducing pollution impacts in the manufacturing process of new materials
Recycling existing materials (roof tiles, bricks, timber, etc.) and designed for conducive re-use

Choosing and Using Materials Sustainable way
Reducing energy in the transport of materials (try sourcing heavy, bulky materials locally and lightweight materials globally).
Using prefabricated components (reduces waste and dust on site).
Use of low maintenance materials to reduce further energy and resource use in the future
