Abstract
The optimal life span of a building component depends on a full-cost analysis, including environmental consequences at the moment of new construction and demolition. Balancing of various cost consequences and the comparison of competing technical solutions needs a transformation on an annual basis. Reducing annual costs may be effectuated by lengthening of the life span by introduction of flexibility; i.e. reuse of components in different positions. This needs a split up of adaptation into decomposition and installation costs. The choice out of technical solutions is only possible when a functional demand period scenario is available for the services to be generated by the building as a set of technical solutions.
