 As the comparison of the simulation and measurement results shows, such a model can provide accurate results ([AkkP 5] (see Figure 1), but this requires a lot of effort and in addition, not all required data are of equal importance. Even so, inappropriate values for "unimportant" data can lead to incorrect results.  \\

 Through comparison of different simulation models the Passive House Institute was able to pinpoint the key data which was necessary for preparing accurate balances, even with simplified models and justifiable effort for data acquisition [Feist 1994]. The method for admissible simplifications is described in the publication [AkkP 13]. It is surprising that even with a simple model, i.e. \\
