| Abstract | Building sector is responsible for 40 % of the primary energy use and 24 % of carbon dioxide emissions in India. The main source of green house gas emissions from buildings is due to energy consumption. This paper aims to assess the embodied energy index and environmental impact of a two storied residential building. The study proposes various alternative materials which can be used in day to day construction in order to mitigate the environmental impact and climate change due to construction activity in India. Two types of construction techniques have been considered for the study, namely load bearing and reinforced concrete framed construction. Embodied energy and carbon dioxide emissions of walling and roofing components using conventional and alternative materials has also been analyzed and compared. The comparison is done based on two parameters namely, embodied energy/m$^{2}$ and CO$_{2}$ emissions per unit of floor area. The study shows that bricks, cement and steel are the three major contributors to the energy cost of constructing a building by conventional methods. A conventional two storied load bearing structure is 22 % more energy efficient when compared to a reinforced concrete structure. It has also been observed from the study that use of alternative material in the building envelope gives embodied energy savings between 50 and 60 % for a two storey load bearing structure and 30–42 % for a two storey reinforced concrete structure. Hence a load bearing construction is certainly a better alternative to RC framed construction for up to two storied structures in terms of embodied energy and environmental impacts. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
