After this is easy. Than, you just need to add four edges of regular decagon. That’s it!

This construction is very similar with first optimized and calculated Neolepenism basis and it’s with similar performances. Instead of edges of decagon you may apply the arc.

In this way, the Neolepenism basis is strongly connect with Golden ratio or Golden angle (137,51 degree) which is applied in the Nature and the architecture.

This shape can use Sun radiation (light and heat) in the most effective way.
