High U-Values lead to big deviations between hourly and monthly calculation #125

The "worse" U-values for envelope components are, the bigger is the difference of calculated energy demands between the hourly and monthly approach. @Linwal has this occurred to you too? I guess it is because of the underlying calculation approach but I have to check whether this is not a different/bigger problem.

So far, I could not find any issue causing this trouble other than the different calculation between the two approaches.

Thank you for pointing this out. It must be something that depends on the dynamics of the heat transfer because these mechanisms are different in the RC Simulation compared to the quasi-static approach of SIA380-1.

I'll have to further look into this.
