If a window has a Sun protection (adjustable in the building data), it can be lowered automatically in case of high solar radiation. The threshold values for this can be taken from DIN 4108-2 - for residential buildings 200 W/m² when facing north and 300 W/m² otherwise, for non-residential buildings 150 W/m² in the north and 200 W/m² otherwise. You can also use "Manual" to define a fixed day profile (for non-residential buildings this is only valid on weekdays, no Sun protection is activated at the weekend). Alternatively, the sun protection control can be taken over from the usage profiles.
Passive cooling
Passive cooling can be provided in the building, the maximum cooling capacity of which is entered here. The maximum cooling capacity is entered here. It is distributed to the rooms according to the demand in the individual hour, i.e. rooms with higher cooling demand get more.
Ventilation
The air exchange can be increased by opening the windows during the period of stay, when the room becomes too warm and it is cooler outside (increased daytime air exchange up to 3/h). At night there must also be appropriate possibilities for increased ventilation (up to 2/h with window ventilation). The high night ventilation (up to 5/h) requires ventilation possibilities across floors. Depending on the dimensioning of a ventilation system, other values can also be set here.
By activating the option "Apply ventilation to all rooms" the room-wise settings are overwritten (table on the next page). However, night ventilation is only taken over for rooms whose windows have a g-value of 0.4 at most when the sun protection is closed, since according to the standard, such a sun protection must also be provided in this case.
