Endesa World Fab Condenser by MARGEN-LAB in Barcelona, Spain

Endesa World Fab Consenser is a thermodynamic prototype, a bioclimatic dome now installed in the currently changing Glorias Square (Barcelona) on the occasion of the BCN Fab10 congress (the tenth international conference on digital fabrication).

The prototype explores connections between parametric design, passive climate strategies and local CNC manufacturing.

It was designed on a global scale (Margen-Lab in collaboration with IAAC and the Fab Lab Network), the materials are renewable and have an organic origin (wood and linen, materials grown with the sun) and manufactured locally (industries and fabrication laboratories from Barcelona and vicinity).

The prototype was designed (written in code) in 2 months, manufactured in 5 days and assembled in 4 arrived with the help of volunteers from Fab Labs (fabrication laboratories) worldwide.

digital fabrication and parametric design logic
simplify prefabrication and the assembly process.

01 DIGITAL PREFABRICATION:

Digital technologies are transforming the old ways of understanding prefabrication. They are changing the ways in which the industry manages its productive ways. And, most importantly, they are changing the interaction between designer, industry and raw material.

The pavilion consists of 20 triangular modules. The components are all different but share the same formal, constructive and material logic.

Parametric design allows us the possibility of working with geometric complexity and variability. At the same time, the mathematical logic that organizes such variability allows, with digital fabrication tools, to share prefabrication strategies and accelerate communication processes (machine design) and production and construction processes.

The algorithm (the entire pavilion is a script) was designed in 2 months, prefabricated in 5 days and assembled in 4.

02 PASSIVE CLIMATE STRATEGIES:

The dome pursues to render the surrounding thermodynamic and climate processes. The initial geometry (a regular icosahedron) is first deformed and adapted seeking to minimize the incident solar radiation in the summer, and to maximize it in winter.

The skin bulges or balloons outward, more typical of sailing geometries, to accelerate wind speeds (vernoulli) and facilitate the use of cross ventilation. The orientations of the north-south openings follow the prevailing wind directions (mountain-sea) generating alternative patterns of ventilation (morning-evening).

The surrounding 200m2 wood stage acts as a reservoir of fresh air, naturally injected into the main space through the perforations on the stands every time the wind blows.

03 KM0 ARCHITECTURE:

Digital fabrication has the ability to bridge the gap between raw material, post-production, designer and end user. The project then becomes the design of the entire projected life cycle of the product. The project is the production chain.

The prototype was designed globally (with the collaboration of the Fab Lab Network) and manufactured locally (using local materials and products and fabrication laboratories and industries in and around Barcelona).

All materials used are of organic origin (linen and wood) and obtained locally. All industries and companies involved in the process are medium scale and located within an 80km radius.

Finally, the assembly process is fully reversible. Wood and fabrics are easily removable (in just one day) and easily reusable or recyclable.
