Kurzfassung englisch:
A probabilistic method based on a decision tree is presented 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. The tool accounts for different user
behaviours and the most important building parameters resulting in the spread of the indoor climate.
In the first part of this paper an approach for a probabilistic tool to predict the interior climate is presented. Factors like
moisture production, ventilation, etc. are brought into a relation to forecast the indoor relative humidity. The influence of
parameters like moisture production or ventilation on the indoor climate can now be easily observed.
In the second part the fault tolerance of the construction is used to calculate the life cycle costs. Depending on the amount of
moisture which is accumulating from year to year, the lifetime of the construction can be determined. By varying
environmental and constructional parameters the solution with the lowest life cycle costs can be determined. Using this method
the decision for a certain roof can be made incorporating durability aspects, energy requirements and costs.
The work is done according to the Austrian participation to IEA Annex 55.
