Brick wall

It is a great pleasure to share this amazing example of good architecture with all Facad3s followers. There is no formal boasting, no latest generation materials, no added gadgets for energy production, no raw land or straw. The building manages to be attractive by being clever, and sustainable by being reasonable.

Have a look to this façade solution, to the characteristics of the different layers overlapped, and then have a look to the Torre Agbar façade solution.

They look quite similar: a wall, in one case made of small elements while in the other made of concrete poured on site, a ribbed metal sheet, glass slats. In both cases the thermal insulation is in the inside.

Interesting sub-frame solving the window opening in all the façade depth. It includes the banister and a gap specially designed to hide the sun protection ¡inside the cavity of the rain screen façade!

Very narrow, large cladding pieces are attached longitudinally. The high number of horizontal profiles that are needed is increased by the fact that two adjacent plates do not always share fixing profiles, as in the lattice area. Therefore, the need for profiles is practically doubled in these parts of the façade.

A very suitable but expensive solution.
 

Unlike stone, pressed ceramic tiles or any kind of artificial panels of board type, extruded terracotta elements can easily be three-dimensional, due to the manufacturing process. Unfortunately architects do not always take advantage of this possibility, even though terracotta is a common material in façade claddings.  Here is a good example of its 3D possibilities!

And observe these difficult corners where three-dimensional elements can show their hollowness! A good challenge!

Sober architecture but a confusing solution.

Which is the main façade layer in this concrete façade? The 8 cm think concrete panel or the brick wall? 

A group of residential buildings in Torrelago district, Laguna de Duero (Valladolid), has been refurbished in the context of the European Programme CITyFIED: Replicable and Innovative Future Efficient Districts and Cities. The renovation addresses both the image of the buildings and energy factors. 

The Hotel Constanza is part of the Illa Diagonal complex. Like the main building, the facade is solved with a travertine rain screen. It is striking the narrowness of the draining cavity, interrupted by the lack of cleanliness in the insulation solution surrounding the fixings.

But, beyond this execution problem, we want to highlight, especially thinking on the architecture students that follow this website, the importance of defining the cutting of the stone cladding and its relation to the position of the windows.

ETICS solutions, which are now so common due to the thermal insulation continuity they allow, were already used twenty-five years ago in designs such as the MACBA building. At that time, achieving continuous rendering without joints was not that simple, as the rendering materials were not as good as the ones we use today.

Lightweight solutions for the rainscreen outer layer were barely known. Probably because the architects did not trust this solution, the inner wall was completely covered with a watertight membrane.

This could not be more adequate.

It is wise in the decision of being discreet, and acute in the selection of all systems and materials. The expertise of the architects as constructors is shown in the accurate design of all the points of relation between the systems and elements.
