Auditorio y Centro de Congresos El Batel. Selgascano. 2011

Audtitorio y Centro de Congresos El Batel
Jose Selgas, Lucia Cano
Cartagena Spain

The Auditorium and Palace of Congresss in Cartagena sits along the maritime façade of the city 200 m long. It is constituted of different volumes of different sizes situated next to each other like big industrial containers. The different spaces use different colours and this is highlighted by the colour used on the façade. 
You enter the building in the extreme west of the volume and from here a descending passage begins in which you lose the reference of which level you are on from the exterior. There is a white space with orange benches. The natural light passes through a double layered system of clear acrylic panels in which they have longitudinal lines of colour in their extrusion (to be seen next).
The building goes further down which eliminates the distraction and relation to the exterior

Below the ground level the structure is made entirely out of reinforced concrete. From above this, nearly all of the other structural elements are metallic. The slabs only have one line of central support which are made of a big metallic profile. Above this is a composite slab. So the pillars along the facades are seen as little as possible between the translucent façade, they are set in two supports each with three metallic tubes  in them. The two layers of the façade are fixed to light lattice work which are put vertically in between the pillars. There is a camera between the two layers which acts as a thermal mattress.

The metal pillars of the façade are the part most taken care of of the whole design. They are 80 x 22 cm in profile and up to 9.4m in height and they have to be as least present as possible. 

                            Extruded Acrylic Slats                                                 Polycarbonate Tubes                                       Aluminium Profiles
The building has three different outer skins depending on the amount of light required, the interior spatial effect and the function of each space. 

These extruded acrylic slats make up most of the façade and the interior finishes. Each of the sections were specifically designed by the architects. There are two different types of pieces, A and B and they can be put in two different positions. They are either white or coloured in blue with different lines of different colours and tones extruded in the slats. This colour is inserted at the time of extrusion.
Transparent units of these slats are used in the two layers of the façade and on the interior spaces they are white. 

In the main auditorium, they have put these slats in shades of blue and green with some vinil strips stuck on to it to give an aquatic atmosphere. 

Whole system

The façade of the other Auditorium is constructed by an industrialized system of free standing sheets of galvanized steel filled with rock wool.

To this support is fixed the special pieces of vertical substructure which is stainless steel cut by laser on top of which the polycarbonate tubes with different colours cover the exterior.

The triangular profile of aluminium constitutes the west façade. The Urban Artist Spy was the author of the design in the façade that marks the access and the beginning of the sloped passage.
