Life cycle analysis and embodied energy: A review

Buildings consume a massive amount of energy during the life cycle stages of construction, use and demolition. Total life cycle energy use in building can be classified into two components: embodied and operational energy. Embodied energy is worn in the processes of building material production, on-site delivery, construction, maintenance, renovation and final demolition. Operational energy is used up in operating the buildings. Studies have discovered the growing consequence of embodied energy characteristic in buildings and have established its relationship to carbon emissions. Present understandings of embodied energy are quite indistinct and differ widely, databases of embodied energy agonize from the problems of variation and preeminence. This paper discusses the various types of embodied energy considered in the life cycle analysis of building and various methods along with there applications and limitations in the Calculation of Embodied energy.This Paper forms Part of a project that also studies the embodied energy calculation of a building throughout its life cycle.
