The building industry has regularly been criticized for resource exploitation, energy use, waste production, greenhouse gas emissions, and impacts on the landscape. The growing population demands more built environment to accommodate the socioeconomic wellbeing. Adopting conventional construction practices would continue the aforementioned issues. Therefore, it is important to integrate life cycle thinking into building construction to minimize its social, environmental, and economic impacts. The objective of this study is to assess the life cycle impact of commonly used wall–roof systems for low rise commercial building construction in Canada. A framework is developed to assess different building alternatives using the triple bottom line of sustainability. Identified environmental and socioeconomic impact indicators are eventually aggregated to develop a life cycle impact index. Material quantities of …
