Two grids organized in three different planes (049)

The Inbisa Tower case study permits us highlighting those subtle design strategies that make a building with four apparently identical facades be so suggestive.

The facade is organized from several overlapped grids. Pillars and slabs cladded in aluminum draw the main order: a grid of the scale of the structural system. Over this grid, some mullions define a second order of the scale of the windows. This second order runs literally over the first grid, regardless of whether what is behind is blind or transparent, breaking the rigidity and scale of the main order.

Despite being the mullions that define the rhythm of the windows, the glass closure is framed between pillars and slabs, that is, between the elements that draw the greater order. The solar protections in the south orientation, formed by glass of low solar factor, are the only elements arranged between the mullions.

Two grids organizing each façade, the same time that the elements in those grids are placed in three different planes. The plane of the glass is aligned with the inner face of the pillars on the south, east and west facades, reducing that way the incidence of direct solar radiation over it. In the south façade, the aforementioned solar protections hang from the outer face of the mullions. A game of shadows and reflections gives depth to the facade.
