The building poses an alternative to the air-conditioned, sealed-envelope, energy-certified office environment. First, the glass curtain -wall gives place to a faceted ceramic-clad envelope which, through shape, maximises summer radiation reflection and winter solar collection. Second, the convective air-conditioning system gives rise to a water radiant system which tempers the office space through high-inertia concrete slabs. Thus, structure and performance are integrated by means of its envelope and its environmental control systems.
