TL;DR: In this article, a case study building at IIT Madras campus was found to have lesser embodied energy compared to conventional buildings and the inside temperature was reduced by 2 °C which will help in reducing the air conditioning requirement of the building and thereby the operational energy.
Abstract: The tremendous housing need of India is causing the depletion of virgin building materials. In an era of scarce resources, sustainable solutions are always preferable. Glass Fibre Reinforced Gypsum (GFRG) technology is one such solution where all the structural members are constructed using hollow panels infilled with reinforced concrete (RC), as per structural design. This paper discusses the sustainability of construction using GFRG panels in terms of embodied energy and indoor thermal comfort. The case study building at IIT Madras campus was found to have lesser embodied energy compared to conventional buildings. The result is significant considering the fact that the building sector consumes 40% of the total energy in world. Also, the inside temperature was found to be lesser by 2 °C which will help in reducing the air conditioning requirement of the building and thereby the operational energy.

Abstract: This paper aims to assess the factors favoring the adoption of the challenges faced and support mechanism, which will lead to the proliferation of glass fiber-reinforced gypsum (GFRG) technology in India.,Semi-structured interviews with 35 experts, including construction developers, architects, contractors, government officials and design consultants, were conducted. This qualitative data was analyzed using thematic analysis and matrix analysis.,GFRG-based buildings produce much less carbon footprints as compared to traditional ones and can be safely recommended as a promising, environmentally sensitive technology of the future. The major drivers in its adoption are its efficient construction capability, energy and soil conservation and significant waste reduction. Some of the challenges in implementation are long planning time, lack of skilled labor, lack of awareness about green building technologies and myopic perception of high cost incurred in green building adoption in people’s minds.,This study establishes that the construction industry has the potential to contribute toward creating a sustainable and green planet. It does so by evaluating and then positively positioning GFRG as an environmentally friendly building system.,The harmful effects of continuous environmental manipulation by humans leading to its degradation is a critical discussion agenda for most nations of the world. The issue has been taken up seriously by developing countries, and now, developing countries are also becoming sensitised to it. Several policies toward the attainment of this goal have been formulated and are being implemented by government and private bodies. Although some authors have studied the issues and challenges related to the adoption of green buildings, their attempts mostly focused on developed countries. Moreover, research that investigated the evaluation of the GFRG building system as a successful green technology of the future is inadequate.
