summary:Credit-reductions by banks, as a consequence of the global monetary crisis, will hit the construction industry for many years to come. There are however still financing opportunities for building projects that are perceived as less risky. Buildings that are not only sustainable, but also flexible and adaptive, are becoming attractive alternatives for traditional buildings. Many innovative concepts are combined in a new form of contracting, called the Living Building Concept. In this concept, buildings are continuously adapted to changing user and/or client needs in the form of Product/Service combinations. In this paper we will zoom in on the implications for building information modelling and construction ICT. Object based, parametric design technologies become more important than ever before. The new business concepts require a life-cycle modelling approach in which individual components and materials play a central role. Buildings are considered as temporary configurations of these components and materials. The functional life of buildings, which strives for higher and sustainable end-user value, becomes detached from the technical life of building components and materials, offering new opportunities for reuse, remanufacturing and recycling.
