Study of Embodied Energy by Data Comparison for Highrise Building

Energy is essential aspect for the life time of any building. Structures are estimated in terms of their energy requirement and eventually their impact on environment to find their sustainability in due course of time. This assessment of energy is considered as widely developed topic. This energy in building is divided into two main stream based on their functions, i. Operational Energy ii. Embodied Energy. The Operational energy is the energy that is required to support the energy, whereas the Embodied energy is the energy that is enveloped in making the building initially. The selection of the materials or techniques used for construction or infrastructure project directly affects the total embodied energy of the structure. Thus selecting a structural system with less Embodied energy may reduce the overall embodied energy of the building. In this study, embodied energy is derived through rigorous exercise of counting the total materials used, their material, transport and different process energy and the total accounted for two different structural systems in high�rise buildings. For which earlier works done in the field is used and help of professionals taken. At the end of the study, it is concluded that the embodied energy for RCC frame building per unit area of that high�rise building is more than the embodied energy of similar scaled Steel composite building. The difference for the case studies used is almost 15%. The percentage figure looks not so significant, however, the total embodied energy difference which is counted in GJ is huge when compared toe to toe. The study thus suggests, that selection of structural system, especially for high�rise buildings with respect to their embodied energy can affect positively on the overall environment impact of the structure.
