In IEP, the courtyard and the interior office space are perceived as a continuum. This close relationship between inner and outer spaces is one of the most interesting aspect of the building. The facade solution is the necessary resource to achieve it. This glass enclosure is freed from any structure just by making the glass work like plates resting on two supports instead of four.

The facade that closes the south face of the tower seems from the outside as a simple stick curtain wall of little interest, if it was not for the fact of being photovoltaic. However, we have dedicated it a section here given the uniqueness of the space it contains and the abstraction in its design that this allows. This curtain wall is the enclosure of the elevator core and, therefore, is devoid of many of the requirements of a facade.

The world of the facade, in constant evolution, allows us to conceive today a "conventional" façade in terms of the layers order; not conventional according to the building construction techniques and materials.The main sheet is a discontinuous structure that allows to lodge the insulation in its thickness. The inside finishing is also resolved over a discontinuous structure. Only the rendering is still a rendering, although analyzing its composition and benefits we see that innovation has also reached him.

Beyond the geometric complexity of Libeskind´s architecture, we want to draw our attention to this curtain wall without transoms that closes the double height entrance hall of the Grand Canal Theatre. The objective is to enhance the verticality of the plane by means of relatively close mullions and the absence of transoms. Unfortunately the black sealing cord takes on an unexpected protagonism among a tangle of white profiles, clear glass and most of the finishes in the hall also white.

The curtain wall that closes the large openings of this public library is solved by looking for the neutrality of which we spoke in "Steel mesh reinforced ETICS (019)" referring to the ETICS solution.The slenderness of the mullions, steel platens instead of tubular profiles, the absence of mullions in the corners; and the negation of the interruption that might have been the intermediate slab; are resources aimed at dematerializing the skin establishing a very intense visual connection between the interior and exterior spaces.
