Transformable building is an innovative design and construction strategy. It aims for an adaptable building stock and fosters the future reuse of construction materials. As a result, long-term environmental and financial savings could be realised. Nevertheless, a feared increase of the initial cost impedes this strategy’s widespread implementation. To frame this impediment and gain better insight into the financial consequences of transformable building, the present research proposes an enhanced life cycle costing method. Taking into account the circular service life of transformable buildings this method empowers advisors and designers to evaluate the feasibility of transformable building and implement it in a well-conceived way.
To take into account the circular service life of transformable buildings as well as their unpredictable and dynamic nature the proposed method departs from life cycle scenarios. Such scenarios or imaginable futures reflect our varying requirements. To facilitate their integration in the life cycle cost analyses the present research developed five new features. These features include specific calculation methods as well as detailed modelling protocols. To illustrate their added-value an in-depth case study is conducted. The study’s outcomes show how scenario based life cycle costing allows to compare initial and long-term costs, evaluate model uncertainties, identify boundary conditions, understand design improvements and study investment risks.
