Comme nous avions déjà annoncé en Mai, et comme il est annoncé sur le site de Rhinoceros,  HDA démarre une nouvelle activité en collaboration avec Rhinoforyou, et organise des formations Grasshopper intégrant un Atelier pratique d’Architecture Parametrique.
Un de ces cours de formation est prévu à Paris du 20 au 22 septembre. Nous souhaitons proposer les 3 formules suivantes en fonction des besoins des stagiaires:

- 3 jours ( Initiation+Atelier ) : du lundi 20 septembre au mercredi 22 septembre
- 2 jours ( Initiation ) : lundi 20 et mardi 21 septembre
- 1 jour ( Atelier ) : mercredi 22 septembre

Les 2 premières journées sont consacrées aux « fondamentaux » de Grasshopper avec en préambule une introduction au design et à l’architecture paramétrique et leurs impacts dans la conception, la création et la construction. La troisième journée sous forme d’atelier est dédiée à l’étude de cas concrets proposés par les stagiaires, qui, quelques jours avant la formation, pourront envoyer leurs projets par mail à info@rhinoforyou.com.

As we have already announced in Italian just befor Christmas, our proposal won the “pylons of the future” international competition for italian energy supplier Terna.
Hugh Dutton explains his intent as it follows:

‘Our own design response is based on changing the current ‘industrial soldier’ image of today’s pylons. Primarily by an elegant shape whose form is inspired by nature instead of galvanized trellises. And secondly by what I called “dancing with nature” where the pylons lean and swerve in response to the topography. They find a structural equilibrium by leaning into the curve of the electric cables as they follow the constraints of the landscape.’

Symbolically this represents a very important project for HDA, as it expresses our deep conviction that new technologies, both in the design phase and in the construction phase, represent a powerful tool to optimally individualize architectures. This thereby avoids the banality of modernism standardization, whilst limiting material wastage, in a similar process to nature’s own selectivity and optimization.

In the design phase, parametric processes are used for design calculations and form determination, the simple profile can be easily adapted to the specific constraints it has to respond to. Further, non linear analysis optimizes the calculation method, taking advantage of the elasticity  from prestress forces. In the construction phase, the pylons are fabricated from flat steel plate cut to individual shapes using contemporary numerically controlled tools. Each individual shape is automatically transferred to the cutting tool one by one from a computer. The flat sheet cut-out shapes are assembled together onto simple jigs and welded using automatic continuous welding machines.  Steel is itself a renewable material, that can be melted down and reformed for new uses.

These technologies are the same that HDA have already successfully used for the arch – photos below – of the Turin Olympic Footbridge, realized in 2006. In fact, «Pylons of the future» represents a refinement of the same design and construction process in which HDA profoundly believes, where architecture, technical constraint and technology are integrally combined.

Finalmente possiamo dirvelo. La settimana scorsa, il 16 dicembre, ci trovavamo con HDA a Roma, in occasione della cerimonia di premiazione del concorso Terna per l’ideazione di una nuova tipologia di piloni elettrici destinati alla realizzazione sul territorio italiano.
Come annunciato oggi dal quotidiano La Repubblica, il progetto di Hugh Dutton (HDA) ha vinto il primo premio e vorremo condividere con voi il nostro progetto, proposto nell’ambito del raggruppamento GIORGIO ROSENTAL (capogruppo), HDA Hugh Dutton Associés, Gozzo Impianti e CEGELEC Solutions & Services.

La nostra proposta consiste in un pilone in tensegrity che, grazie all’utilizzo delle tecnologie della lamiera saldata e il taglio a controllo numerico, adatta la propria forma e l’inclinazione ai movimenti del terreno e “danza con il paesaggio”. Questa proposizione, applicata a un “oggetto” fin da sempre percepito come appoggiato sul territorio in maniera astratta e insensibile, rappresenta una sfida radicale che coinvolge non solo l’architettura e la sua implicazione ecologica, ma anche altri campi come l’innovazione tecnologica e culturale.

Torneremo a parlare di questi temi in seguito; per il momento, se volete saperne di più potete scaricare il comunicato stampa, dal quale abbiamo estratto alcuni brani del testo di presentazione di Hugh Dutton:

“Voler ideare un pilone elettrico in armonia con la natura potrebbe addirittura sembrare una contraddizione. I piloni tradizionali sono il simbolo stesso dell’intervento insensibile dell’uomo sul paesaggio.
Questi soldati industriali in marcia attraverso il paesaggio, gabbie di tralicci in acciaio galvanizzato, sono strutture certamente ottimizzate ed efficaci ma senza poesia.” [...]

“Concedere l’opportunità di riflettere su un rapporto nuovo di questi piloni con la natura ci appare allora come un segno di apertura e sensibilità.
L’epoca che stiamo vivendo è caratterizzata da interrogazioni profonde sul divenire del nostro pianeta; la questione ecologica è al centro delle preoccupazioni dell’uomo contemporaneo.
Il futuro sarà fortemente condizionato dalla risoluzione di tali quesiti.
In questo senso, la nostra sfida è che i nuovi piloni diventino un elemento integrato nel paesaggio, nonché un simbolo contemporaneo di una relazione con la natura che superi il contrasto per tendere alla simbiosi.” [...]

“La natura, scegliendo le forme delle foglie o delle piante, non è guidata da un’estetica puramente intellettuale. Piuttosto, la forma è la configurazione spaziale che definisce in modo inevitabile il rapporto di ogni oggetto con le forze della natura che lo circondano (vento, luce, temperatura e molte altre). I nuovi piloni si piegano per rispondere meglio alle forze che li sollecitano e, allo stesso modo, la loro sagoma é concepita per rispondere nel modo ottimale alla luce solare che li investe. Essendo la luce ciò che rende percettibili gli oggetti e che ne conferisce la loro qualità visiva, è evidente che questo aspetto sia di primaria importanza. In questo senso, i profili triangolari dei piloni fanno in modo che, da qualsiasi punto di vista, una sola faccia sarà visibile, evitando contrasti ombra/luce e massimizzando la luminosità dell’oggetto architettonico, che apparirà bianco e slanciato.” [...]

“…possono inclinarsi per esprimere le forze variabili che sono loro applicate, come un uomo che si sbilancia contro il vento forte per cercare l’equilibrio. Allo stesso modo, i piloni dialogano con la geografia del terreno e le linee di forza che ne risultano. Piuttosto che dominare il paesaggio come soldati insensibili, esprimono l’idea che la natura è la più forte in questo rapporto.
Abitualmente si considerano i supporti per l’elettricità’ come elementi standardizzati tutti uguali che possono essere installati in qualsiasi luogo indistintamente.
Al contrario un pilone elettrico ha una sua unicità che dipende da molteplici fattori: la posizione che occupa nel paesaggio, i carichi dovuti a condizioni atmosferiche differenti, le inclinazioni e la tipologia dei suoli sempre differenti” [...]

Complexitys blog was conceived amid much brainstorming and deliberation, and with much enthusiasm, but with little idea of exactly which direction it would proceed in. Little more than two months after its birth and we’ve been surprised and encouraged to see the first important result of our devotion to, and investment in, an open online communication of architecture.
As Domenico Di Siena from Ecosistema Urbano Office explained in our “web for architects” training in Paris, “an architecture office’s blog is not a portfolio or a place to talk about themselves, but rather an incredibly powerful tool to create a community around the office’s activities and interests”.
Two months into the project and several blogs worldwide have begun talking about complexitys, so these words are now becoming reality.

We would like to thank these blogs personally, as they encourage us to keep working on ours:

DIGITAG& – Italian-based blog with an international reach, which aims to tag contents about digital architecture.

RHINO OFFICIAL BLOGS (French, English and other languages available) – a special thankyou to McNeel’s staff for their constant support for complex geometry and modeling issues, such as the Unrolling Double Curved Surfaces (and by the way, thanks too to Lowell Walmsley for his DevSrf Rhino Tool support).

RHINO CON Ñ – a Chilian blog which describes us as practicing an #openculture (thanks for that).

ArchDaily – a very important architecture blog talks about our last footbridge in La Roche sur Yon in France.

Furthermore, this blog and our twitter (mainly thanks to #gh3D and #rhinoscript ashtags) have enabled us to come into contact with many people who share our interests, such as Pier Paolo Presta and his blog, Rodrigo and his DesignPlayGrounds and the blog UN DIDI, with the wonderful Massive Unroll tool (which we used to produce the image shown above, available in a free wallpaper format here).

So many thanks to all of those who follow us. We would gladly welcome comments and/or suggestions on how to further develop our blog, and we will continue to give regular updates and continue to evolve.
We will soon be introducing an Engineering category, run mainly by HDA’s engineers, for those interested in more technical and scientific content relating to architecture and complex geometry.

We are happy to post our first entry of our new DOWNLOADS category.
Like a small but growing number of other architecture offices (such as Ecosistema Urbano and Arquitextonica), we believe that sharing content can be useful, productive and not anti-economic.
In other words, we believe in an Open Culture.

That’s why on this post we want to share with you in a free download format, a rhinoscript code (see video above) that we developed for a skylight design in China, which can help with understanding the concept of double and single curvature geometry.
If you are new to rhinoscript, it may help you to have a look at THEVERYMANY, where you will get a better idea of what can be achieved within this format.

This code was written to achieve a free-form skylight design with a glass roof,  a cable truss and 100 shading blades. The script was necessary due to the time it would have taken in drawing the elements one by one.
If you are architect and used to working with complex geometries and surfaces, you are probably aware of the difficulties and intricacies of double curved surfaces. In many of our projects at HDA we have to deal with these issues on a regular basis.

The basic premise is that you have a free-form surface and it has to be built. A free-form surface (with double curvature) is difficult to build because the surface is not developable; you can’t unfold or unroll it, so you can’t build it from a folded flat panel (i.e. glass or ruled metal panels). In architectural practice it’s always preferable to transform double curved surfaces into single curved or flat surfaces (this last case is especially suitable if you are using glass, which is very expensive to deform).

In the slideshows below you’ll find for your reference two of the project where we had to solve problems related to double curved surfaces.

The first slideshow is the Paris Philarmonic Hall (with Arch. Jean Nouvel) and the second is the Publicis Drugstore, situated on the Champs Elysees in Paris, where all the glass panels are single curved, and therefore give the impression of free-form geometry.

You can download here our free package containing two simplified rhinoscript files, one for generating single curved panels (A) and the other for generating flat panels (B), and a rhino file that can be used as a base to test and play with the script. In the rhino file you’ll find a few base geometries which can then be used as a start point to run the script, and a set of layers that will help you to manage the large quantity of geometry generated by the script.

As shown in the video, the script will ask you to chose a set of lines to use as the base of the geometry (they just have to be mono-oriented as in the image above), the starting height, and (only for script B) the number of flat panels you want (12 by default). There are possibly (probably!) some bugs within the script that I didn’t notice, and admittedly the code is quite poorly annotated, but I hope you will be kind enough to ask us if you have any problems, we’d be happy to help and to develop the tool together with you. We would also appreciate any comments about the idea of publishing things such as this, as we are continually looking to understand the best way to do it in order to build a constructive platform for debate.
The following images show the geometries resulting from running the script in the Rhino file in the downloadable package.
Please also remember that you need Monkey to run rhinoscript files. You can download it for free here.
