Ornament

Posted on May 25, 2011 by team

(input lecture by Barbara Imhof June 2010)

The discussion about the ornament might have started with Owen Jones work „The Grammar of the Ornament“ at the end of the 19th century and Jones becoming a well-known English architect and stylist ‘pro ornament‘: “From universal testimony of travellers it would appear, that there is scarcely a people, in however early a stage of civilization, with whom the desire for ornament is not a strong instinct.”[1]

Currently, we are at a stage of ‘Re-sampling the ornament’[2]. Since some years several architects around the world, practicing and teaching have been pursuing this topic. Being based in Vienna, one also takes a look at it’s famous architectural roots, thus Adolf Loos‘s essay „Ornament and Crime“. Again, a hundred years later this article was resounding throughout the land of architectural debate. A debate which in Loos’ sense was about social, economic, art-theoretic, historic, and psychological issues. To Loos the ornament was also an add-on onto a surface and (just to take one of his arguments) something which leaves less payment for the person who did it, since an ornamented box carved by a Chinese worker (same issue today – a 100 years later) was the same price as a box with a smooth surface. According to his argument a human needed to work less and save time, health and money if objects could be done without an ornamental appendage. Loos, referred with this to functional objects or new interfaces such as the telephone and to (then) contemporary architecture. Loos wanted to free architecture or objects from the emotional expendabilities and he discussed this in an era of early mass production, efficiency, and in the city where Sigmund Freud explored the expendabilities of the soul. At the same time the last white spots of earth got explored. In the early 20th century western humankind took (for the first time) an anthropologic and scientific approach to unknown territory and its population; still far from what we would consider politically correct. For Adolf Loos, the indigenous population of Papua New Guinea and their body ornaments came from tradition and that he acknowledged.

Generally speaking, everything around the ornament theory is complex, ambiguous and definitely opens a lot of layers of interpretation. The discussion has been ongoing among architects ever since including Luis Sullivan, Le Corbusier and Gropius and others; however, all of them were not either for or against it – it depended on the context. The Unite d‘Habitation in Marseille by Le Corbusier also incorporates ornamental enrichments from one of the modernist architects.

Louis Sullivan who coined the phrase “form follows function“ wrote in his “Ornament in Architecture” theory: “… I should say that it would be greatly for our aesthetic good if we should refrain entirely from the use of ornament for a period of years, in order that our thought might concentrate acutely upon the production of buildings well formed and comely in the nude. …”[3]

Again it is quite intriguing – the ambiguity the architects show in their statements, in their interpretation and in their philosophy. According to Jörg Gleiter[4] the most recent buildings (amongst others) sparking the debate again were e.g. the Trutec Building by Barkow Leibinger Architects and Ben van Berkels shopping centre in Kaohsiung City in Taiwan.

Today, the new ornament is probably something more computerized, algorithmic and relies very much on contemporary manufacturing technologies. Again, the economic issue arises: it might become cheaper now to incorporate the manufacturing of the ornament through new technologic achievements in machinery. That and computer technologies – software – go hand in hand with the return of the ornament.

In many disciplines such as textiles, fashion, design and architecture the discussion has been stimulated through these advancements. If Adolf Loos would have imagined this what he would have said since he believed that we will slowly turn away from the ornament through many generations might be worth a guess over an easy dinner discussion. However, looking forward we could quote Walter Gropius and would probably be ok with: “Forward with tradition, the ornament is dead, long live the ornament!”

Critical to a contemporary understanding of the ornament is it’s from old times existing relation to nature. We would like to augment the topic through an interdisciplinary approach and analysis not limited to free association or basic investigation of nature, or purely bio-inspired. In this way the authors of this report think about Biornametics: Biornametics is an artificially created word – from biomimetics and ornament.

Biomimetics in Architecture

Posted on May 25, 2011 by team

(input lecture by Petra Gruber June 2010)

Biomimetics in architecture is the use of biomimetics as innovation tool for application in architecture. It is an emerging field that develops the interest of architects and designers in role models from nature further to a new discipline. The strategic approach differentiates biomimetics from mere inspiration from nature, that has always existed in architecture, arts and technology. Bioinspiration can transfer pure morphological aspects, whereas in biomimetics functional aspects play a key role. In general, materials, structures and processes from nature can find biomimetic transfer to new technical solutions (an overview of Biomimetics in architecture is to be found in P. Gruber: “Biomimetics in architecture – the architecture of life and buildings” 2001). Until recently the methodology of biomimetics in architecture was only roughly described, meanwhile there are a few attempts to grasp the process and discern distinct phases and methods (works of Thomas Speck, University of Freiburg, and Biologically Inspired Design group, Georgia Techn University).

In the Biornametics project, the introduction of a biomimetic approach was meant to deliver a strong connection between the role model from nature and the architectonic interpretation, going beyond inspiration and transfer of form. Several possibilities for application of patterns are foreseen. The basic ornamental depiction of natural patterns from nature would be the most simple translation. In the case of the Ricola Mulhouse factory (Herzog & de Meuron 1993) the facade panels are printed with a repetitif plant motif derived from a famous photograph, delivering also a symbolic information on the functional use of the building. Facades lend themselves for application fields of 2D as well as 3D elements having aspects from nature as an underlying model. One of the first active adaptive facades was carried out in the Institut du Monde Arabe in Paris (Jean Nouvel 1988), using a system of technical apertures to control light conditions inside. Recent projects, the EmTech diploma program at the Architectural Association being on the forefront of these, use computer aided technologies to transfer differentiated elements from nature to building shells.

DEFINITION OF THE RESEARCH AREAS

Posted on July 21, 2010 by team

During the first project team workshop at the beginning of June 2010 three main areas of investigation for role models from nature were defined for the Biornametics project:

  1. Surface patterns, Nano-surfaces[1] and Nano-structured materials
  2. Shape, Growth, Deployable structures
  3. Adaptation, Reorganisation

These three areas were chosen to reflect the specific scientific expertise in the project team: an expert in fibre structures, therefore the role-model focus rather on plants than on animals, and an expert in nano-surfaces and structural colours.

Thus, the sample role models from nature to be investigated are chosen with regard to

  • Availability of reliable information
  • Tangibility of scales and processes
  • Exclusion of biochemistry and metabolic processes
  • Expected innovative potential for spatial and architectural applications

The methodology applied starts with a selection of role models from nature (scientific input). At the same time a primary investigation in successful transfers, architectural applications and outcome scenarios will deliver exemplary knowledge and guarantee novelty of the selected approach.

The base of Biornametics, patterns and their scientific exploration, shall find a feedback in the architectural theory of the ornament. After the first phase of data collection, the computation of models follows and the concept development and design starts thereafter.

The first transfer takes place when the selected role model patterns are analyzed regarding their potential application and their abstracted principles. Digital simulations will be used to examine the principles and evaluate them. In the second transfer analogy is established by exploring applications where the abstracted principles can be applied.

The final step is the proto-architectural implementation of showcase applications that will be exhibited and distributed to the scientific and architectural community by means of a booklet and scientific papers in journals and conference proceedings.

1. Surface patterns, Nano-surfaces and Nano-structured materials

Surface patterns, Nano-surfaces and Nano-structured materials as found in a selection of model organisms constitute one part of the Biornametics research project.

Biological systems exhibit a wealth of functional units highly optimized for a range of parameters, also on the nanoscale. Biological building strategies rely basically on repetition, variation and self-similarity. Often simple building blocks are arranged with molecular-precision and thus achieve diverse and highly specialized material properties.

The research performed in Biornametics aims at understanding the functionality of these natural patterns by extracting the principles found in current nanotechnology research, and transferring these principles to an architectural interpretation.

Colours are just one very important example. In contrast to pigment colours, physical colours that are found on some butterfly wings and beetles are primarily determined by the geometry of the underlying material.

Interesting is also the generation of these surfaces and materials, as well as properties such as durability, degradation or self-repair.

Further examples include plant-environment interaction like for example the pitcher plant that lures animals onto a supersliding surface, or the well-known self-cleaning principle that was discovered in the lotus leaf. Patterning on the nanoscale also produces materials that have unequalled properties like for example the abalone shell.

The patterns found do not only fulfil their purpose but are surprisingly elegant and appeal to the aesthetic dimension of the human perception.

The transfer of surface patterning to architectural elements may deliver added or integrated functionality or reinterpret specific functions on another scale.

2. Shape, Growth, Deployable structures

The topic of morphogenesis in nature is about the development of shapes in general. In the context of Biornametics the interest lies in the dynamics of shapes and shape change.

The topic focuses on the ontogenetic development of three-dimensional complex shapes (in contrast to an evolutionary perspective) and on other phenomena related to shape change in organisms.

The development of organisms is based on cell division, the basis for the generation of tissues and organs. The principles of cell growth as investigated in microbiology can be included, but the focus of the topic lies on the research findings in developmental biology.

Interesting issues are the principles of growth in organisms and the differentiation of tissues and materials. The time-based rules of growth and the spatial geometric definition of growth principles (growth patterns) are focused.

Specific topics, for example branching, are included. Deformation relates to the topic Adaptation and Reorganisation, and is about form change due to disturbances.

Especially in the plant realm the relation between growth and deployment is of interest. On a shorter timescale we are interested in fast deployment, or more general, fast shape change in organisms, that aims at for example defence or attraction purposes.

The research of mechanisms leading to shapes and shape change in nature will go beyond the generation and control of complex geometries by establishing a strong link to efficiencies and functionality. This is a focus in current architectural research and development.

3. Adaptation, Reorganisation

The topic Adaptation and Reorganisation treats the stabilisation capacity in dynamic and living systems.

The adaptive capacities include structural change that might affect physical properties like strength, stiffness, or mass/surface ratio.

Adaptation can also refer to organisational aspects for example the implementation of failure tolerant systems or mass management tools in case of circulation.

Adaptation and reorganisation in biological systems are triggered by a change in environment that the organism or system is either subjected to or actively looking for. Therefore methods of adaptation comprise active, explorative strategies and passive, responsive methods to environmental changes. Examples for both explorative strategies and response can be found in climbing plants, lianas and vines that actively look for a suitable environment and react to change in structural support with reorganisation of tissue.

As in these cases, adaptation is often achieved by local decision-making and local differentiation.

The topic focuses on long term processes that aim at creating or re-establishing equilibrium in a dynamic system, that can deliver valuable strategies for the creation of built environment.

[1] Nano refers to one thousandth of one millionth. 1000 million nanometers are one meter. A human hair is about 70 000 Nanometers thick. Nanoscience and -technology deals with functional structures on a length scale of some tens to some hundreds of nanometers.

Science To Architecture: Design By Research

Posted on June 29, 2010 by admin

Lecture invitation to the European Forum Alpbach, Barbara Imhof and Petra Gruber talk about “Science To Architecture: Design By Research”, Wednesday, August 25, 2010

Abstract
——————————————————————————————
In the same way as the scientific progress blurs the boundaries between the natural world and art world, an increasing convergence of disciplines can be recognized. Using a scientific mode of operation in architecture does not only allow to investigate the past and the present: “Design by Research” describes the research into the future in designing with scientific parameters, an approach which can also be defined as “Scientific Design.” In the project “Biornametics” natural patterns are studied to explore their potential for innovative applications in architecture. The methodology of biomimetics will be used to transfer principles from nature – especially their correlation of structure and function – into technical applications. “Biornametics” is conducted in the context of previous projects including research the field space design.
