Although life cycle assessment offers insight into the long-term value of our building stock, it has become impossible to model with certainty the service life of a building. What if new lifestyles make reality diverge from the expected service life? What if the building is decommissioned very early or forced to accommodate new functions? Would the same design decisions have been made or would an alternative have been preferred? In reaction to this challenge, the present paper proposes to integrate scenario planning and life cycle assessment. Therefore, it discusses from where scenario planning originates and how it appeared hitherto in architectural design and life cycle assessment. Thereafter, it explores how assessors can profit from scenarios when raising awareness and co-creating alternatives. Subsequently, a methodological framework for effective scenario development is proposed. To illustrate the added value of scenario integrated life cycle assessments, four divergent scenarios are developed for evaluating the financial feasibility of demountable building element reuse. With this simple case study is shown how more relevant and nuanced assessment outcomes are obtained when divergent scenarios are adopted.
