-It was shown that the heat output in very well-insulated buildings, actually measured through scientifically monitored projects, had a much lower upper limit for output than the design output in accordance with the [DIN 4701] standard, even at extremely low outdoor temperatures. This was first published in [Feist/Werner 1993] based on the measured daily heat consumption values in the Passive House in [[examples:residential_buildings:single_-_family_houses:central_europe:the_world_s_first_passive_house_darmstadt-kranichstein_germany|Darmstadt-Kranichstein]]. According to these results, there is a kink in the horizontal curve for the measured daily mean heating loads below about 0 °C. This correlation was correctly explained in [Feist/Werner 1993] by solar energy gains during the colder weather periods and discussed in more detail in [Feist 2005]. Accurate heating load results simply cannot be obtained without taking into account solar gains, particularly in very well-insulated buildings.
