17. 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. http://en.wikipedia.org/wiki/Indian_vernacular_architecture

19. 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.

20. 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.

21. 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

22. Aspects of buildings Political Cultural Historical Environmental Natural Social Economical

24. 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.

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

26. Materials Choosing, using, re-using and recycling materials during design, manufacture, construction and maintenance to reduce resource requirements. Towards Sustainable Development…

27. Towards Sustainable Development… Waste Producing less waste and recycling more Pollution Producing less toxicity, water, noise and spatial pollution.

31. Working Principles

32. 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.

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

34. 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

36. 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
