| Abstract | This study discusses the obvious gap in the Life Cycle Energy Assessment literature. Much of it only focuses on initial embodied energy and pays little or no attention to recurring embodied energy. This paper presents a study on embodied energy analysis considering both the initial and recurring embodied energy in typical linked double-storey terraced houses over a 50 years' building service life. The findings from the study provide insights into embodied energy and the significance of recurring embodied energy in contributing towards the building energy demand. The embodied energy of the houses ranged from 8.05 to 9.85GJ/m2, with an average of 8.95 GJ/m2 while, the recurrent embodied energy ranged from 2.37 to 3.49 GJ/m2 with an average of 2.93 GJ/m2. The average recurrent embodied energy equates to 33% of total embodied energy, and this component can significantly influence the life cycle of embodied energy. The study also identifies building materials that can significantly reduce the embodied energy demand. |
