ABSTRACT: The handloom sector constitutes a distinct feature of the rich cultural heritage of India and plays a vital role in the economy and cultural identity of the country. It is an ancient industry and is source of livelihood for many villages in India. Its spread varies in style, practice and scale throughout the country -in certain regions it is has a proficient industry, while in others its establishment is localized, where it is a family-based activity. While, hand-woven fabrics are well-sought after both nationally and globally, weavers currently remain marginalized and often impoverished. The well-set power loom industry has further added to their woes. Given the progressive failure of centralized production and distribution ideologies, handlooms represent a decentralized distributed means of livelihood security, environmental consonance, employment generation, skill enhancement, cultural (diversity, identity and) integrity and sustainability. The fabrics and dyes used in the handloom industry are environment-friendly and often unique to a region (based on available skill and resources). The paper comprehensively evaluates and forecasts sustainability in the context of traditional handlooms in India. Results of the study and recommendations are presented in this paper.Environmental engineering and management journal 06/2012; · 1.00 Impact Factor
Conference Proceeding: Thermal Performance of the Building Walls[show abstract] [hide abstract]
ABSTRACT: A building’s climatic-response is determined by the prevalent exposure conditions (micro-climate) and the ability of the building envelope to regulate thermal transmittance (building physics). This ability to passively thermo-regulate indoor thermal comfort is determined by the materials configuring the envelope geometry. Various building envelope configurations are feasible depending on available/accessible building resources. In this study, the thermal performance of a building envelope, viz., a masonry wall has been investigated. The theoretical investigation is carried out under steady periodic conditions (occurring in natural building environments). A numerical model based on the implicit Finite Difference Method (FDM) has been developed for the computation of thermal transmittance. Six different wall configurations have been identified based on those typically used in commercial and residential buildings in India. The influences of both material thermal properties and external surface heat-transfer coefficient on the time lag and decremental factor have been investigated. The heat load transmission through the interior wall surface has also been studied. Most studies have arrived at time lag and decrement factor as critical performance measures of a building envelope, but under constant exterior surface heat transfer coefficient considerations. While it has been observed that the heat transfer coefficient does not remain constant, its variation has a bearing on both the time lag and decrement factor, and require careful investigation. The results of the numerical analysis show that decremental factor decreases while exterior heat transfer coefficient increases. Further, the thermal properties, thickness and material assembly are other important factors that determines interior surface instantaneous heat load. Further, it was observed that walls with the higher time lags and lower decrement factors were suited for adoption in tropical regions. The current study attempts to augment existing knowledge of building climatic response leading to appropriate envelope designconfigurations for various climatic zones.1st IBPSA Italy conference, Building Sumulation - 2013 (BSA 2013), Free University of Bozen-Bolzano, Italy; 01/2013
Conference Proceeding: Sustainability of handloom IndustryN C Balaji, Monto Mani[show abstract] [hide abstract]
ABSTRACT: The hand-loom is an ancient industry in India and its use varies throughout the region, it has become a mature industry, while in some parts of India it is still used primarily as a household staple. Handloom production is a family-based activity and is inseparable from the living atmosphere of the handloom families. Handloom sector constitutes a distinct feature of the rich cultural heritage of India and plays a vital role in the economy of the country. The weavers are typical of rural Indians left behind by market forces, rapid development of industry (Power loom) on an extensive scale. Self sustainability is becoming more important with the energy and environmental crisis. Hand-looms are environment-friendly and are an independent and autonomous in technology. The industry presents a quality on itself to sustainable development and reduction of negative impacts on environment and ecology as well as providing sustainable employment for rural India.International Congress on Environmental Research (ICER - 2010), Mauritius; 09/2010

ABSTRACT: In this paper the results of an experimental investigation carried out to determine the load carrying capacity of brick masonry dome in mud mortar is reported. Dome has been constructed without using formwork. Dome of span 3m, thickness 0.075m, and central rise 0.6m has been considered in the study. The entire outer surface of the dome was subjected to uniformly distributed load of upto an intensity of 2.845kN/sq m. Further more, the dome was also subjected to partial uniformly distributed load around the crown upto an angle of α = 6.309 degree measured from the crown.International Symposium on Earthen Structures. 01/2007;
