Abstract. Contemporary Architecture experiences new ways of space envelopment that satisfy the influences of past utopias from more than one point of view: aesthetic, energy-wise and structure wise. All these experiments present in the interior-exterior interface should answer one simple question: Can we consider Contemporary ways of space envelopment intelligent skins? In this study, intelligent building features are focused on the façade. The intelligent skin sometimes becomes part of the building and adjusts the fastest to the changes that happen. Physical pressure on the façade created by the development of adaptive Architecture leads to its transformation. The most visible changes in the façade are present in the interior-exterior interface characteristics. The façade should be the most adaptive part of the building that has to change according to the needs of an Intelligent Building. The external limit for the interior space should protect and breathe within a continuous communication process with the exterior. The main case study for architects could be efficient spatial configuration in order to reach the final purpose of creating the intelligent building. Historical references will gradually conduct the research towards creating a methodology that follows evolution from micro to macro structure and then from inert to adaptable features of buildings.

Keywords: Adaptive Architecture, Envelope, Dynamic Façade, Experimental Architecture, Interface

1. Introduction The contemporary ways of space envelopment create new influences that are visible to the interior-

exterior interface and become important for both theory and practice of Architecture. The main case study for architects should be efficient spatial configuration in order to reach the final

purpose of creating the intelligent building. Architects are not so keen anymore about the management of the building. But the end-use of the

building is also part of intelligent management and design of living spaces, therefore part of an architect’s job.

2. Historical references

Vitruvius stated the first example of how to build intelligent Architecture by properly positioning the building in the town or in the relief. The protective role of the wall started from the city wall as it was in town where he lived. The cela model of Architecture with a porch in front, for shade, describes the system of conditioning temperature for the interior during summer.

„On this principle of arrangement the disagreeable force of the winds will be shut out from dwellings and lines of houses. For if the streets run full in the face of the winds, their constant blasts rushing in from the open country, and then confined by narrow alleys, will sweep through them with great violence. The lines of houses must therefore be directed away from the quarters from which the winds blow, so that as they come in they may strike against the angles of the blocks and their force thus be broken and dispersed”.[1]

Visible from the envelope level, the system created by Architecture is well reflected in space by cardinal points positioning, on the dominant wind or even according to the star-signs[2] that Vitruvius mentions.

During time, the façade evolves from massivity to total transparency: 1851 Crystal Palace- Joseph Paxton. After having built this, transparency was meant to evoke and then evolve to the conceptual dematerialisation.

Using the vernacular houses model, architects understand that walls are mediators between human body needs and exterior environment.

In the end of the 19th Century and the begining of the 20th Century the entire system of enviromental technologies called HVAC (heat, ventilation and air conditioning)[3] frees the walls from their role as enviromental mediators. But the intelligent building has to use in a better way all these advantages. For example, a glass façade should come with an air conditioning system and blinds for saving energy during ventilation.

Intelligent buildings seen from outside were at first an illusion or a manifest. Starting with Georges Pompidou Center from Paris, Renzo Piano and Richard Rogers showed all the installation to the outside of the building as if it were the extension of a brain.

Later on in Paris, at the Arab World Institute, Jean Nouvel shows to the sunny South an adaptive façade full of mechanical diafragms linked with the construction brain which coordinates devices that open and close creating shade for the interior.

Intelligent buildings are much more than just that or strictly a form from the architect’s point of view. They have created a technology that adjusts the interior to the shape of living.

Spatial wise, the façade is the one that envelopes the interior space, but the intelligent building shows all its technology through it. Adaptive features make a façade more dynamic and also create the illusion that the façade has a possible movement which was speculated by architects in time.

At the Venice Bienalle architects experimented with concepts of a building that uses internal temperature or humidity totally different than usual. In 2008 Philippe Rahm Architects come with the idea that architects should no longer build spaces but start creating atmospheres and climates. The visual effect was not very present, but the temperature control was associated with other sensory stimuli like: cinnamon, garlic, mint, camphor and chilli for every range of temperature.

In 2010 using the same temperature control, Transsolar and Tetsuo Kondo Architects, create an ambiance named Cloudscapes. This is a project where visitors are invited to feel the effect of the density and temperature of the water vapors condensed into a cloud. This time, the cloud is visible and accessible through a spiral ramp. So the possibility of passing through makes this experiment more direct and easier to understand for everybody.

In the context of climate change people should realize that living in a space can more than just that, especially if a building is supposed to adapt intelligently and solve more and more adjustment issues in the very near future.

3. Intelligent Skin, Intelligent building Green Architecture, building energy saving and enviromental protection are actually the new challenges

in Architecture. Architects are constantly aware of the materials they can use in creating façades. The use of new technology and experimentation in building envelopment are also of high interest to professionals in constructions. While architects have to confine to space and its envelopment, technology experimentation (provided by other sciences) and material experimentation are made through traditional or innovative techniques. The relevant issues of this project are still in the experiment phase worldwide. Some of them are still unsolved, others are in a proposal stage or even utopian, but most of them have materialized in iconic buildings.

Sometimes living buildings and green buildings are specific cases of intelligent buildings. They behave like Bodies Without Organs [4] in the Deleuzian [5] sense of the heterotopian [6] relationship with the body as a built entity loses the sense of being mearly an envelope of the building and becomes an entire parasitary universe attached to the building.

Neoplasmatic Design is the theme of the 2008’s last issue of Architectural Design Magazine, that approaches the subject of building envelopes from the material perspective and use. The manipulation and the control of micro-organic matters in Architecture[7] are research directions on how biology, microbiology, biotechnology, surgery or cloning connect with the Architecture field.

Inversabrane[8] is a research material of DuPont Corian company from the solid surfaces’ category, used in public spaces and desirable in the role of a Green wall – better said Alive wall. The features of this material such as: air and water purification, bulletproof character make it very attractive. It is also seen as an evolution of life. People can groom it where needed. Ever since 2005 this material started to be put at use in Architecture projects and competitions. Architects appreciate it and have created a new Aesthetics around it.

Computer generated solutions in Architecture have lead to the development of the Body Algorithm [9] starting from the 80’s utopias until today’s free expresiveness. The parametric character of design software offers architects endless choices of space envelopment so that they focus on how to create an intelligent building.

Materials used in the building façades are diversified and science is set to bring something new that revolutionizes this field. Biology is the science that Ecology and Green Buildings expect most of. Adapting plants to form a structure on their own could be one challenge, their behavior related to sun for building parts could be another one, and growing interchangable parts of the building could be the final goal.

Biology and Botanics along with these materials are more of an interface or a membrane capable of protecting the inside in a suitable environment for inhabitation. The intelligent building should turn after the sun, conserve energy during the day and use it at night, when needed. Technically speaking, nothing is impossible, but the costs of achieving it are ever too often high for a self-sustainable unit like this.

Wyss Institute conducts research on materials’ adaptability to different conditions like: moist and pore-closure, resistance, adaptive speed, etc. Another feature of materials that is very useful to constructions is their memory: reversible elastic deformations and their restore to the initial shape after being deformed.

Living materials are features to be used in Adaptive Architecture. Microscopic environments reveal invisible configurations in wide spaces/ large surfaces of architectural dimensions. [10]

Just as playing „GO” cells get together by forming tridimensional junctions and protecting the nucleus/core when they are mature. Life offers protection solutions as well as attack weapons, therefore inspiration for cellular Architecture is provided even by a virus or bacteria that is dynamic enough to occupy space and create a membrane.

Adaptive Building Initiatives produce adaptive façades and building envelopes, designing adaptive mechanical systems. [11]

Perhaps our ideas on space are wrong. Maybe space in constructions should not be simply erect and wait there for us, but adjustable so that it contains us at the moment of transition. The Stratus Project develops a kinetic interior envelope. [12]

All this research will influence the future of the building envelope and the idea (concept) of intelligent building will change along.

The Solar Decathlon is a competition that has the goal of self sustainaing a 70 sqm house. All these examples are not necessarily intelligent buildings with an integrated system of management but by their own adaptive features are self efficient. Finding new adaptive features for the building skin will be the challenge for new experimentation in Architecture.

In the Treescraper Tower of Tomorrow leading architect William McDonough shows his commitment to creativity, intelligent building and designs that feed ecosystems, and also expresses how a System integrated Building could be visible through project. [13]

These things are more than useful and necessary to a building. But the adaptability of the envelope is much more important in the context of shape-function-significance the main trinomial of Architecture – and any suplementary constraints that are meant to help inhabitation but not improve the Aesthetics of the projects and interior spaces.

Architectural features have to deal with differences between the useful skin and the ornamental package, even if Adolf Loss wanted to finish this 100 years ago. Contemporary Aestetics like the Prada store in Tokyo designed by J. Herzog and P. De Meuron looks like it deals with both aspects.

Building Skin or Inteligent Skin are problems that concern inteligent buildings and the adaptive features of the skin if are put correctly in the building envelope the result will be amazing for the confort parameters.

Inteligent Skin [14] is analysed by a set of factors called intelligent controls: Daylight adjustement- reflection/protection, Glare control- blinds/louvres/fixed, Responsive artificial

light control, Heating control, Heat recovery- warm/cooling, Cooling control, ventilation control, fabric control- windows/dampers/doors, Insulation- night/solar.

”The building façade should no longer be regarded as a static and inert barrier, but a Dynamic enviromental filter with the energy passing through it ripe for exploatation.” [15]

4. Adaptive architecture Inhabiting adaptive Architecture means living in a dream house or a fiction like Boris Vian’s [16] where

the walls fall and understand you so they act in consequence. One of the latest conferences that focused mainly on Adaptive Architecture was organized in London,

Great Britain, in March 3rd to 5th 2011. Adaptive concerns were divided in 4 main subjects: Dynamic Façades, Transformable Structures, Bio-Inspired Materials, Intelligence. Sensory responsive architecture will be examined including dynamic, responsive façades and communicative building fabric systems that are capable of reducing energy demands whilst creating comfort and the integration of energy generation into contemporary architecture.

Hyposurface created by Mark Goulthorpe is the model for Dynamic Facades that is why he was invited as a Keynote speaker. His speech called Die Plastik refers the intelligent skin as an adaptabile one using all the features for an inteligent building.

Inhabitation of Adaptive Architecture also means a progress in the performance of the space envelope. Living in such a place is now more and more close to reality through new technologies and experiments in Architecture.

These experiments that happen in the contemporary envelopment process have to be categorized on several criteria. Materials categorized according to texture, geometry or colour gain dynamic characteristics like: light, text, vibration are typical in scenography.

The technology in use or the technique, as well as original ideas’ presentations in relation to shape, function and significance will offer the study two points of interest: theoretical and mostly practical.

Shape-Function-Significance form a trinomial that defines Architecture and suggests the importance of form in space composition. This is the reason that enveloping spaces is one of the archetipal concerns of Architecture.

The central element in the study of Architecture is space. Therefore any scientific research have space as main study object and the issues of space envelopment are just as up-to-date as the primordial shelter in contemporary times as well as in the future of an architect.

The interior-exterior interface through the analysis of shape characteristics in Contemporary Architecture is best defined formally according to the feedback shared with the trinomial formed by shape-function-significance.

“Intelligent skins” present different technological methods of expressing the interior-exterior interface. A separate section of the study is dedicated to gathering ethnic and religious elements from the 20th Century as well as an analysis of the interior-exterior interface manifest in Romanian architecture.

Contemporary architects are lately interested in enveloping spaces with perfect skins which solve aestetic and energy-wise problems at the same time. Adaptive Architecture use dynamic façades, transformable structures, bio-insipired materials in creating inteligent skins for building.

We should see if adaptability could be another feature that Architecture develops in the future. The main goal of this scientific research is creating a system of experimental architecture trends present

in the envelope structure. The conclusions go beyond the subject of dematerialization of the interior-exterior interface and gather

the premises of a contemporary way creating adaptive Architecture along with the designing process. The interdisciplinary character of the study generates new approaches in future scientific research

regarding experiments in space envelopment.

When the sun is at the equinoxes, that is, passing through Aries or Libra, he makes the gnomon cast a shadow equal to eight ninths of its own length, in the latitude of Rome. In Athens, the shadow is equal to three fourths of the length of the gnomon; at Rhodes to five sevenths; at Tarentum, to nine elevenths; at Alexandria, to three fifths; and so at other places it is found that the shadows of equinoctial gnomons are naturally different from one another.
