Stepped shed roof allowed for functional use

Hello!

In our development plan / building design statutes, the following paragraph can be found on the topic of roof shapes:

Staggered shed roofs are permitted as an exception if
a) functional aspects (e.g. energy-saving measures), especially regarding the arrangement of windows in the shed offset, justify this
and
b) the shed offset, measured up to the upper edge of the roof surface, is limited to 1.20 m or the roof overhang at the offset to a maximum of 0.40 m.

I would like to implement a staggered shed roof because I like it very much, but I do not know how to comply with the conditions described above. In particular, I wonder how such an offset can be used for energy-saving measures. So far, I have not found anything on the internet that shows me a connection here. The only thing I can think of is that windows in the offset could allow light and thus warmth from the southern direction to enter the northern half of the house. Or are there more possibilities?

On the northern side of the house in the attic, we are currently planning the two children's rooms. In order to let light into these rooms through such windows, they would have to extend up to the gable. Isn't this rather counterproductive in terms of heating demand?

Hello,

We then plan PD in combination with SD when the orientation of the property to the sun is unfavorable and we can use the south side with PD; especially when more solar panels are desired. The same applies to sufficient lighting of the rooms located beneath the PD.
