This will set the thermal strategy for this building, which consists in capturing the most sun possible
This made it to function with only 25% of the normal office building use of energy, this by studying the building form and geometry to achieve less solar gain and heat losses, with the help of a strong thermal envelope.
This building is rather big for being a sustainable building, this is because it is often believed that this kind of buildings have to be small and compact, rather than big and open like this one.
