This document discusses the objectives and work of Building Centres in India, which aim to promote sustainable and cost-effective construction technologies. The key points are: 1. Building Centres disseminate information and provide training on affordable eco-friendly construction techniques like stabilised mud blocks and reinforced brick construction. 2. The first Building Centre in India started in the 1970s in Kerala to transfer technologies from labs to the field through demonstration projects, manufacturing building components, and research. 3. Over 385 Building Centres have been established across India, training over 55,000 masons and others. Projects using alternative technologies completed through these centres have saved 15-40% in costs.

- 2. Building Centre / Building Technology Park -Concept Indian Building Centre Movement The objectives of Building Centre 1. Technology Transfer in the field of housing, building and development disseminations information on cost effective environment friendly and appropriate technologies in urban/rural areas through live projects. 2. Skill Upgradation and Training on various cost effective construction technologies 3. Manufacturing and Distribution Outlet eco friendly and cost effective building materials are made available to users including public agencies and individual home builders. 4. Developing Entrepreneurship for manufacturing and marketing of cost effective building components. 5. Hoiusing Guidance Centre a decentralised information and counselling centre for technology dissemination 6. Disaster Mitigation mass scale training, reconstruction, retrofitting and strengthening programme in disaster like earthquake, cyclone and flood affected areas with appropriate and cost effective technologies.

- 21. Load on the lintel d on the lintel Corners being pushed inside rs being pushed inside OPTIMUM UTILIZATION of material is utilized by designing the lintel in such a way that it can transfer the load of the wall with minimum use of material and strength. Thus saving on cost and labor with just simple addition of flange to the lintel Sagging of lintel SMB oppose corners from coming inside. Hence stop lintel sagging.ence stop lintel sagging

- 53. Sustainable architecture is inbuilt in tribal culture since childhood. Architecture might seem inconceivable without architects, but the richness of “Primitive” tribal traditions show that humans have an instinctive grasp of how to build , how to apply ornament, how to situate forms in landscape and how to give genuine meaning and structure to the rituals and romance of existence.
