Abstract: The built environment is a significant contributor to global green house gas emissions. In many industrialized nations, more than 40% of carbon emissions are the result of energy consumption by buildings. Using the right materials in our homes can help preserve the environment and save our money in long run whether we are constructing a new building from ground up. Using energy efficient building materials can save our hundred even many thousands of rupees not only in energy savings but also in tax incentives, grants and rebates. Low energy materials may be used for construction of floor, slab, roof slab, walling system, false ceiling, inbuilt furniture, internal partitioning, paneling etc. in order to reduce the overall embodied energy of the building structure. As per literature studies/ survey more than 70% of the total materials used in the building interior should be low energy or energy efficient. Hence, choice of the building material is very important in reducing the energy contents of building. This paper is focused on energy saving in building using energy efficient green building materials. For this purpose an institutional building constructed in the campus of IIITM Gwalior is visited during its construction and is taken as a case study
