KL University, ACE-2011 Vijaywada,A.P, Recent initiatives to promote innovative building material technologies 1.Technology transfer at national level Building Materials & Technology Promotion Council (BMTPC) was set up in 1990 under the aegis of the erstwhile Ministry of Urban Development, to bring together scientific research, technological advancements and enterprise. 2.Technology transfer at grass-root level-A centrally sponsored Scheme for establishing a National Network of Building Centres was launched in 1988- 89. The Scheme is being implemented through HUDCO and so far over 653 locations have been identified and more than 490 centres have already become fully operational in several States. 3.Other facilitating measures- BMTPC facilitates establishment of new building materials production units by providing technology backup services, and coordinating with concerned departments/agencies for necessary policy supports, credit facilities and venture capital supports4.Fiscal Incentives-Fiscal incentives for promoting new building materials technologiesis an important facilitating feature of Government’s policy support for housing andbuilding sector.

KL University, ACE-2011 Nirmithi Kendra Vijaywada,A.P, "Nirmithi Kendra"The housing shortage in India is estimated to be 40 million units by 2000 A.D. andprovide an opportunity to search for feasible solutions. It was in this context that the"Nirmithi movement", the project described herein, was started in 1985 as a localinitiative in the Quilon District of Kerala, by the then District Collector.In 1985, for providing affordable solutions to housing, Indias first "Nirmithi Kendra"(Building Centre) was set up in the Quilon District of Kerala . Arising from itsimpact, the Government of India set up such Kendras in all districts of the countryand integrated it with the national housing policy.

KL University, ACE-2011 Vijaywada,A.P, Welcome to Earth Architecture !1.Peviously named the Auroville Building Centre / Earth Unit, which had been foundedby HUDCO, Government of India, in 1989. The development of the former buildingcentre evolved in such a way that the Auroville Earth Institute came into existence in2004.2.The Auroville Earth Institute is researching, developing, promoting and transferringearth-based technologies, which are cost and energy effective. 3.These technologiesare disseminated through training courses, seminars, workshops, manuals anddocuments.3.The emphasis is focused on the research and development of earth basedtechnologies and their dissemination through training courses.4.One of the aims of the Auroville Earth Institute is to give people the possibility tocreate and build for themselves their own habitat, while using earth techniques.

ACE-2011 AUROVILLE VIKAS COMMUNITY Vijaywada,A.P, VIKAS COMMUNITY AUROVILLE Earth was used, from the first developments of Vikas, in all parts of the buildings, from foundations to roof. The proper management of earth resources was always the first priority. The quarries where the soil was taken from were always planned first. This procedure allowed a perfect integration of the excavations with the buildings and landscape. Ar.Suvarna LeleLOW COST AND ALTERNATE METHODS OF CONSTRUCTION Ar,Sarita Deshpande

KL University, ACE-2011 Case study Vijaywada,A.P, AR.Vivek Patankar’s bangalow,Nashik 1)Strip foundations are used below walls. In usual cases the strip is taken below total wall. Here, after designing, it was found out that only 60% length of strip was required so the parts of strip were omitted 2)Brick work-Exposed and rat trap bond 3)The roof -is organization of funicular shells. Each panel is of 900mm x 1500mm. 4)Door frames are made up of cast in situ concrete where the cost of each frame works around Rs. 100/-. The ready made frame costs more than 400 rupees (the rate is around 10 years back) 5)Precast C panels Chajjas and Precast folded staircase. 6)The construction time reduced by nearly 50 days 7) The cost saved in the year 2000 was Rs 2 lakhs for the total for a. The estimated cost for a bungalow of around 145sq costed rs 600000 by using conventional technologies ab 4,80000 using the alternate technologies.

Ar.Suvarna LeleLOW COST AND ALTERNATE METHODS OF CONSTRUCTION Ar.Sarita Deshpande
CONCLUSIONWith the availability of alternate technologies and materials which are much cheaper, thereis a need of transferring them to needy to build low cost houses. Government has dealt thisissue on various levels by creating BMTPC, establishing CBRI, NirmiteeKendras, SERC, CASTRA Regional Research Laboratories, National EnvironmentalEngineering Research Institute and many related organisations.. The technologies selectedhelped to some extent in employment generation, upliftment of women, decentralisation ofproduction, conservation, recycling and reuse of resources as well as development of humanresources.
