Any organization with a headquarters like this is sure to attract attention, but surprisingly, the Pan-African Energy Agency (PAEA) by Stefan Ritter has much more humble intentions than it appears.
It's a very good thing that such a monumental building as this makes an attempt to function passively. A thermal roof keeps the cavernous spaces cool in the summer and warm in the winter, preventing the outdoor temperatures from penetrating and harnessing the strength of the sun where possible. Pipes throughout the glass latticework skin are warmed by its rays, feeding heat into the building where necessary.
The complex architectural composition is an interesting exploration of subdividing masses. While the overall impression of the PAEA by Stefan Ritter is one of epic proportions, the public and private program is pieced apart in separate structural shards.
