Isn't the heat storage more important than the thermal insulation, and isn't the whole U-value calculation method incorrect? | - There are often critical remarks about the the calculation method too:\\ ** Can (stationary) U-values be used in calculations at all?

+ | ==== Can a similar approach also be used to calculate the cooling demand? ==== | ||
+ | |||
+ | Yes, it can. It is exactely the same balance - the utilisation factor will now be applied to potentially remaining heat losses. This is implemented as the active cooling sheet in PHPP.\\ | ||

+ | It is also possible, to give an assessment of the thermal comfort if no active cooling is available: The is based on the [[: | ||
