Abstract

Extensive focus on operational energy research has positively impacted both academia and policymakers, facilitating new strategies that reduce the energy consumed by building occupants. Much less emphasis has, however, been given to embodied energy. Consequently, although studies now show that embodied energy can be responsible for up to 50% of a building’s life cycle energy, little is known about the embodied energy associated with the construction of buildings, materials, and components in the study context. The aim of this study is to investigate the current scenario in the United Arab Emirates (UAE) by calculating the embodied energy of a residential villa, and estimating the initial, recurrent, and demolition and disposal embodied energies over a 50-year building life span. A detailed assessment of the embodied energy associated with the construction of the case study villa was carried out using an input–output hybrid approach, followed by a sensitivity analysis focused on variations related to the energy associated and consumed, as well as the adoption of renewable energy sources. The findings show that the initial embodied energy was 57% of the life cycle embodied energy and 19% of the life cycle energy of the villa while the recurrent embodied energy was 43% of the life cycle embodied energy and 14% of the life cycle energy of the villa. The life cycle embodied energy of the villa, over a 50-year life span was 36% of the life cycle energy. This paper also highlights the impact of adding a solar PV system and lists multiple areas for future studies related to embodied energy and its benefit to stakeholders in the building industry.
