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. 

Unlike what stone, pressed ceramic tiles, or any kind of artificial panels -board type-, can give, extruded terracotta elements can, due to the manufacturing process, easily be three-dimensional!!! A possibility which architects not always take advantage of, even though terracotta is a common material in façade claddings. 

And pay attention to these difficult corners where three-dimensional elements may exhibit their hollowness!!

Although prefabricated concrete panels incorporating stone claddings are not something new -as an example to highlight the Hotel in Plaza España, designed by the architect Enric Garces, and built in 1990-; we want to draw attention on the appropriateness of the solution today.

As we mentioned in the wake of the SBG Schönburg building in Bern, the open-joint claddings are in crisis -not because of their performance, which nobody questions, but merely due to formal reasons.

Rain screen facades solved with thin claddings are a good solution regarding watertightness and the sun radiation protection. Besides that, they permit a wide range of image variations and so are supposed to be a gift for most of the architects. However, for some of them, all those open joint claddings give somehow a sense of lack of robustness; the wall is just a veneer, a vail. 

The term “conventional” is really poor when we refer it to such an exceptional façade; however, and attending the taxonomical criteria we are using in this platform: the material form of the façade supporting elements is amorphous, and the watertightness mechanism is by material barrier.
This example permits us showing how wide is the meaning of each one of the taxons used in our classification, and how poor the common solutions that have helped us to illustrate them.

Sober architecture but a confusing solution.

In this concrete façade: which is the main façade layer? The concrete panel 8 cm thick, 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. 

Load bearing facades are nowadays a common solution due to the permeability they permit in the inner space. Some of those structures are let to be seen from the outside, some of them are not. 
It is not that common resolving this load bearing façade subdividing it into two structures placed side by side; one inside the water, air, and thermal barrier of the enclosure, while the other outside it; one clearly supporting the slabs loads, while the other drawing some kind of stabilizing diagonals. A vertical configuration versus an arborescent outside image. 

There are lots of things to say of each of the buildings we publish in this website. However, from the beginning we decided to focus just in one aspect or curiosity for each of them. 

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.
