sol.ARGE is the playful development of the dynamic sculpture sol.A into a large building, hence the title. As such the intelligence of the sculpture that was created through the careful articulation to maximise the potential of the sun has been employed in the building prototype to maximise natural light, generate solar power through the maximised surface structure, and efficiently utilise thermal loads. The spatial intersection of the two articulated volumes serves to create complex public and private occupation interfaces, for a range of program types.
