   - There are often critical remarks about the the calculation method too:\\ ** Can (stationary) U-values be used in calculations at all?  Isn't the heat storage more important than the thermal insulation, and isn't the whole U-value calculation method incorrect?**\\ No, the U-value calculation method is the correct approach as has been shown by many systematic analyses (see [[planning:thermal_protection:thermal_protection_works:Thermal protection vs. thermal storage]]). The comparison of the energy balance after the calculation and after the measurement additionally proves this.\\
 \\
+==== 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 [[:a_simplified_method_for_determining_thermal_comfort_in_summer_for_buildings_without_active_cooling|passive cooling sheet]].
