English abstract:
A probabilistic method based on a decision tree is summarized in this paper. The tool calculates the impact of a specific roof construction on the life cycle cost and energy efficiency of single family houses.
Using this method the decision for a certain roof can be made incorporating durability aspects, energy requirements and costs. By varying environmental and constructional parameters the solution with the lowest life cycle costs can be determined. In the first part of this paper an approach for a probabilistic tool to predict
the interior climate is used. User-factors like moisture production, ventilation, etc. are brought into a relation to forecast the indoor relative humidity. In the second part of this paper the fault tolerance of the construction is used to calculate the life cycle costs. By varying factors like the interest rate the most sensitive measure on the life cycle costs is evaluated.
