N2 - Studies have advocated that there is much less research on the impact of embodied energy. Researchers have asserted that a building’s embodied energy can be as high as 60% of the life cycle energy. However, there is insufficient research and understanding of embodied energy impacts and its relationship with material specification and service life. This research aims to fill this gap by investigating the life cycle embodied energy of a villa in the United Arab Emirates with particular emphasis on the wall assembly. The findings show that the embodied energy impact of the wall structure and wall finishes was found to be 19.7% and 11.7% of the villa’s life cycle embodied energy (LCEE), respectively. Alternative material service life (MSL) scenarios for the wall assembly shows that using minimum material service life (MSL) values results in a 54% increase in LCEE of the wall, and 74% increase in the LCEE of the villa. For maximum MSL, the findings show a 27% and 31% decrease in LCEE of walls and villa, respectively. Alternative wall finishes show that wallpaper as a replacement of water-based paint will increase the LCEE of the villa by 28%.
