Comparing the life cycle energy profiles of residential buildings in different countries

Buildings are responsible for significant energy use and greenhouse gas emissions, globally. Life cycle energy analysis if often used to assess the total energy use of buildings and identify relevant reduction measures. However, most existing studies underestimate embodied energy, do not consider the occupant’s transport-related energy and focus on a single country. This study relies on a comprehensive life cycle energy analysis framework to assess three different dwellings in Australia, Belgium and Lebanon. Results show that the life cycle energy profile varies significantly depending on the location and is influenced by a range of factors. This study shows that the proposed method can be applied in different contexts as long as the required data is available. By relying on a comprehensive life cycle energy analysis framework, building designers can prioritise the most effective measures to reduce energy use and ultimately the environmental impact of buildings
