Aesthetically Pleasing Efficient Intelligent Building Skins Engineering Essay
Aesthetic preciselyy lovely Efficient Intelligent edifice Skins Engineering EssayArchitecture is no longer static and unchangeable instead it is high-power, responsive and conversant The head that twist skins reflect the skins of living organisms properly intentional, they breathe, change shape, and adapt to variations in clime But bear passing efficient apt skins pacify be esthetic eithery pleasing?A structure becomes a chameleon which adapts. A properly equipped andresponsively clothed build would monitor all infixed and external variables,temperature, hygrometry and light levels, solar radiation etc, to come up the scoop animation equation given these conditions and modify the construct and its internal establishments fitly. It is non too unt mavin-time(a) to ask of a create to incorporate, in its fabric and its nervous system, the actually basic vestiges of an adaptive capability.(Rogers 1978)The civilize of this publisher is to seek the nonion of incorporating news program into a makes fa fruit drink. The discussion ab stunned the energy force of faades has inspired some(prenominal) architects to no longer view the structure gasbag as static and as a kinetic being, that send word adjust its shape, surface, function and upcountry spaces in realtime in reaction to keen tempers that monitor active feed back off from theenvironment. solar and wind energy, mean solar day, and weewee end be capturedby expressions and re apply efficiently. An Intelligent building is one that combines twainactive features and passive form strategies to provide uttermost substance ab using upr puff of aura byusing minimum energy. The intelligent faade forms reference of the intelligent building, itis what protects the inhabited interior whilst controlling exchanges between insideand outside at the gasbag level. The propose being to respond effectively to changing climate conditions and inhabitant reads in order to purify u seful performance. A buildings faade doesnt just play a key role in the sustainability of a building adding to both energy efficiency and the quality of the internal climate. It is as well a fundamental part of the buildings aesthetic, adding to the structural outline and delineate its opthalmic impact on the urban environs. A faade shade sole(prenominal) be described as intelligent when it makes use of natural renewable energy sources such(prenominal) as solar energy, airflows or underseal alter to meet a buildings requirements in terms of heating, cooling and lighting. The sentiment that the fabric of a building can increase its interaction and response to external changes and internal demands with a prime objective of lowering the environmental load is an exciting concept. The facades or so become local, non-polluting energy suppliers to the building.The notion of intelligent building facades is not a new idea however the instruction execution of high-tech skins has b een slow. While fashionable and almost for sure advantageous, sceptical architects argon afraid that in operation(p) components argon magnets for grade engine room or forebode them being stripped off their buildings in the future due to brusk performance or poor maintenance. However, the rising cost of energy, latest environmental initiatives and the focus on the green propaganda has put great responsibility on architects and engineers to make continuous energy savings and this must be achieved through and through effective building design and clever management. Almost seven old age after the European Union passed legislation requiring property sufferers to report on the energy performance of their buildings, a new round of tougher regulations is under means. Plans to revise the Energy Performance of Buildings Directive (EPBD) in 2010 ar expected to final end point in even tighter emissions targets for new buildings. Gradually more and more architects argon bring fo rthning to enjoy automating their facades alternatively than leaving energy-efficient functions to chance. Consequently, the crucial boundary connecting the interior environment and the elements is getting more consideration and consequently more animated. some buildings today ar equipped with increasingly locomote technologies, but fewer still seem to be utilizing the true potential that this green intelligence has to offer. The intention of this study is to take the idea of the intelligent skin much further and realize what could potentially be possible in the future.The paper go forth go on to describe the context within which the aim for variability in building skin performance has arisen and demonstrate how such dynamic response mechanisms work been incorporated into the design and look of ternion buildings The GSW Headquarters in Berlin, by the architects Sauerbruch and Hutton 1999. The Debis Headquarters building, Berlin by The Renzo Piano Building Workshop in 1997 and the B4 and B6 office buildings in Berlin by Richard Rogers 1998. All tether en lesson studies are purpose built office buildings that were built more or less the same time frame and are in the same European climate, Germany. The climate in Berlin is known as continental. The summers are warmer than the UK and the winters colder. summer temperatures can rise to 32 degrees centigrade while winter temperatures can toss out to -15 degrees centigrade.After German reunification in 1990 Berlin was to become the gateway to the substantial former Soviet Communist Empire as it was transformed into an stinting epicentre by new investment from the westbound. A skyline of social system cranes rose over the metropolis, citizens marvelled at the remarkable commitment to entwining a city separated for 50 familys. Berlin bravely tried to reconcile its catastrophic bypast with a new visualization of the urban future. Potsdamer Platz has been the site of the extensive redevelopment, in stigating all three of the buildings in the review. Because of this, the buildings should employ reasonably up to date applied science and design, which can be effectively compared and critiqued in the study. Not only this, but through a growing trend, buildings that employ environmen largey conscious technologies are still the exception in most of Europe today. However bloody shame Pepchinski explains why for many reasons Germany appears to be the leader Many German architects and engineers sincerely care about the effect their buildings make believe on the environment, but others suck up that new technologies will be profitable in 10 to 20 years time. Politically, Germanys powerful Green party also influences national environmental policies. (M, Pepchinski 199570)The overall purpose of this review is to determine whether functional and aesthetic value can be effectively combined in a angiotensin-converting enzyme project while still managing to cut energy consumption. However to chip in whether the buildings have aesthetic significance one must first determine the criteria for aesthetic judgement.Aesthetics examines our response to an object. Judgments of beauty are sensory, emotional and happy all at the same time. Viewer interpretations of beauty possess two concepts of value esthetics and apprehension. Aesthetics is the philosophical notion of beauty. Taste is a result of education and alertness of cultural values therefore taste can be learned. Taste varies depending on class, cultural background, and education. According to Philosopher Immanuel Kant make-up in 1790, beauty is objective and universal thus certain things are beautiful to everyone. The contemporary view of beauty is not base on innate qualities, but rather on cultural specifics and individual interpretations. (Kant 1790)The criteria for assesing whether the buildings are esthetically pleasing in this study will be based on two or more views, that of architects or journalists and my own personalised stamp. Because judging aesthetics depends on individual interpretations, one is hard press to determine the answer, however if based on two views, both can be taken into account, and a conclusion come to. To asses whether the building meets the technological efficiency will be based on performance info or statistics and an engineers view. By also looking at whether or not post occupancy evaluation (POE) methods have been adopted at the as-built stage, involving the views about the buildings from the perspective of the people who use them. It could give vital information on building user perception assessing ease of use, controls, facilities and most importantly perceive visual sagaciousness.GSW Headquarters Berlin Sauerbruch Hutton Architects 1999This landmark office tower is an exemplary archetype of sustainable architecture making use of energy-conserving features. It was the conceptions first thermally flued tall building. The most important aspect of the low-energy concept is the highly transparent and dynamic high-rise faade. Colourful orange and pick apart automated shading panels in the west retell skin endocarp manage solar heat gain and day lighting. These perforated metal shutters give the building its droll and ever varying appearance. They can be both pivoted and moved excursion mechanically or individually by the user therefore the art object of the entire west faade depends on the habits of the occupants. This creates a classifiable dynamic pattern causing the structure to come alive.Whilst elegant in simplicity, form and function, the design results from a highly technical discourse in which the engineering and architectural principles rely largely on each other. The design exhibit involved a high level of collaboration between the architects and the engineers-Arup London. The ten-fold functioning envelope required the main elements of the building to be the result of excellent teamwork. To minimise heat loss both the East and watt perimeter walls are intentional as double skin facades. The West faade acts as a solar flue, it has three storys the inner layer consists of a double sheeny aluminium chill wall in which every second bay has an operable window. The vertical posts of this inner faade carry cantilevering brackets to support the outer faade this layer is single glazed and consists of 3.3m x1.8m laminated ice panels. Airflow within the inner and outer skins of the faade can be regulated according to seasonal and weather conditions by dampers at the top and bottom. Natural ventilation is brought in through the East double skin faade. Fresh air enters the building, passes through the interior spaces, across specially designed corridor openings, and is extracted by the solar flue of the West faade, which offers peculiarly unspoiled thermal insulation. The East faade with its porous ventilation openings is analogous a smooth skin, where as the West faade deep and sepa rated into layers resembles a fur. (UME 200129). The reduced depth of the tower along with generously sized windows allows maximum day lighting, creating optimum conditions on the office outrages making most coloured lighting redundant.The brief noted the building had to be a low-cost, socially sensitive structure, which addressed the historic urban context and street planning, but still provide a strong image as the headquarter of GSW. It also had to have functional quality in connecting new and old buildings whilst ensuring operational environmental efficiency. The overall aim for the mechanical design was to improve the buildings sustainability rating by achieving energy savings of 30-40% in comparison to an run-of-the-mill building. (www.arup.com) the structure is integrated in a three-dimensional composition, offering a working environment which is beneficial to team-working and customer-focused operations. In 1999 natural ventilation was reportedly used for 75% of the ye ar and the building hardly saw the need to operate its air-conditioners. (NSG space modulation) In the Property EU Magazine M. Korteweg utterThe building is excellent in its passive control of energy consumption, with carbon dioxide savings estimated to be 55% of equivalent air-conditioned buildings. (Korteweg, M)In my opinion the tall, slender 85 metre tall structure that is curved in shape adds an interesting addition to the urban skyline. The bright coloured red, pink and orange shutters on the West faade are undoubtedly what makes this building run out from the crowd. It looks like a radiant mosaic, very assorted from the silvery white East faade. I consider colour to be a fantastic medium to address the senses. Colour is used actively in design as a means of generating atmospheric and distinctive buildings, and I think in this structure it plant life particularly well. It certainly looks the part but this buildings image is not just skin deep, it also plays the part in red ucing emissions and saving energy. The fact that these vivid panels are not just decorative but also functional makes the building so much more fascinating. At night the exterior of the building is lit up, making it easily recognisable, even from a distance. Showing how functional and aesthetic value can be united fantastically in a lone project.In the architectural Review magazine, James Russell describes the building asAn array of energy saving strategies and staff amenities in a colourful, stylish package (Russell, JS 2000156)Reunification put the site back at the centre of things, and the colourful new sunniness-shades on the west cover energise the neighbourhood. (Russell, JS 2000156)To sum up this advanced mix of bold impregnable looks and intelligent features and to evaluate the success and failures, I would say that this building works astonishingly well on both levels. The building lives up to what the brief intended.The Debis Headquarters Berlin The Renzo Piano Buildi ng Workshop 1997The Debis Tower was the first building in the initial stage of the huge Potsdamer Platz development, which was anticipated to give Berlin a new spirit. It is a pioneering energy-conserving design an exceptional example of environmentally forward-moving architecture celebrating design and engine room. It comes across as being subtle and rather understated compared to some of the surrounding urban infrastructure. It has a certain bonny and distinguished modesty. The East facade of the tower is dominated by cooky coloured terracotta cladding, horizontal and vertical terracotta slats create an accurately proportioned pattern, which expresses every floor and bay within an overall texture resembling a sort of boney skin.The building is technologically sophisticated it has a highly effective curtain wall, which offers considerable advantages in terms of the preservation of energy, day lighting, user control and comfort. The interior skin consists of a visually delicate and subtle sugarcoat-breathing wall. It features double-pane operable windows, allow the individual inhabitants of the offices to adjust their own internal climates all year round by taking tempered air from the 700mm wide cavity for natural ventilation. The exterior faade is made up of 12-mm thick, automated, pivoting, laminated glass louvers. The delicateest center of air exchange takes place through these louvers when closed. Allegedly the thermal devices designed for the faade work so well that natural ventilation is used for around 60% of the year an exceptional percentage for a building in a northern climate. In addition, there is a 50% decrement in the energy consumption of the building and 70% reduction in the emission of carbon dioxide. (NSG, Space Modulation).Energy conservation was a significant aspect of the design policy for the building and the project was awarded mount from the European Union Joule II research programme to dish up finance the design of the faca des.To create this environmentally sustainable building many factors had to be considered and contribute towards the design. One being water management. The building makes practised use of the rainwater it collects, some of the rainwater is used to irrigate the surrounding landscape and vegetation of the building, some is used as water for toilets, and the tautological is used to fill the nearby pond when the level drops. The building is accounted to redeem around 20,000 cubic metres of water a year. (Arch Review 1998)This building is very distinct from the first case study I looked at. It doesnt make a huge statement, clad in bright, bold colours and doesnt stand out significantly from its neighbours. I think it is delicate and rather subtle in the way it looks. A continuous rhythm of horizontal terracotta louvers interrupted by ever changing individually operable blinds, creating an interesting pattern.In the Architectural Record J.Russell gave his opinion of the building At s ome quantify of the day, the sun sparkles from the bevelled bottom edge of the pivoting glass panels at others, it picks out elements between the glass walls the vertical glass returns, the metal faade-support structure, or the maintenance platforms. The terra-cotta elements dont move, but their raw-claw finish invites touch. The rhythms of open and closed cladding along with deepening and lightening shadows as the light changes through the day have their own sensuous appeal. (Russell 1998135)To begin the process of discussing the successes and failures of the building, I am struggling to find a part of the buildings environmental aspects that can be described as a failure. plane tiny details seem to add to the sustainability of the design. The energy-saving approach of the facades combining terracotta and glass screens gives the building a visually rich texture and a highly practical purpose. The building has an innovative environmental approach and careful design detailing, maki ng it an all round success.B4 B6 office buildings Berlin Richard Rogers 1998Like the prior case study, these two office buildings were part of the much bigger master plan to redevelop the devastated Potsdamer Platz area of Berlin. In this dense urban context the aim was to produce innovative environments for businesses, which must be strikingly contemporary in appearance, and most significantly, utilized a low-energy servicing agenda with a high-quality user comfort. The faades are made up of identical modules of which their basic identical construction can be varied by using different in-fills according to the orientation and performance requirement. This allows different parts of the building to perform in different ways, depending on its specific position. The materials used are clear and obscure glass panels, ceramic tile cladding, and external and internal blinds, a sophisticated mix, which allows the internal environments to be adjusted in response to the requirements of the occupants.The hollow spirit plan form of the office buildings is cut away gradually from cover level down flooding the atriums with natural light. The atriums are entirely of course ventilated. In order to optimise the thermal conditions and airflow in the atrium information processing system simulations were conducted. Solar radiation contributes to the heating and thereby reduces energy consumption in the winter. The natural ventilation ensures that a comfortable climate prevails in the get area and the offices adjacent to the atrium throughout the year. A great deal of daylight enters the offices through glazing this solar radiation is used to heat the fresh air from outside and naturally ventilates the offices. It was estimated that energy consumption in the office buildings would be 50% less than that generated by a conventionally air-conditioned building.When visit this building what initially stood out to me was how much more high-tech it looked than the previous two case studies I had visited. The energy saving devices seem to stand out more and are what primarily make up the interesting, dynamic faade. The building is made up of two blocks, symmetrical from the front. Similar to the GSW headquarters, bright coloured solar shading blinds are used. In this case they are bright yellow, and feature at each end of the building almost acting as bookends. In terms of aesthetics, I think the building is visually interesting and fits in well with its surroundings. Kenneth Powell described the completed buildings as Striking expressions of the rise of an eco-architecture on a grand urban scale.(Kenneth Powell)The union of environmental applied science and design in these three case studies seems to have created visually attractive and interesting facades that credit the surrounding city. However it has been argued that goal of such environmental screens has concentrated on technical developments with little appreciation that facades are the public face of architecture. (Moloney, J. 2007461) this is a strong argument, which I cannot dissent with without taking every case into account. In the past environmentally aware buildings have sometimes been perceived as inept and unattractive. But times have changed. Technology and aesthetics should be able to run alongside each other in harmony. Architects are now beginning to use energy saving strategies to their advantage to create more unique, interesting facades. Solar shading devices can add a huge amount of visual interest to a building, creating an ever changing dynamic pattern, just like the buildings featured in this review.Climate change is undeniable. Therefore the demand for more efficient, next-generation adaptive systems for building facades is increasing. What has the future got in store for adaptive facades? bleak innovations in faade design are primarily down to advanced technical developments in both computer technology and materials. The building envelope is a cri tical area of a buildings design, with the facade engineer playacting a vital role in bringing the architects vision to life. unsanded cladding materials and processing techniques are continually being developed in the search for discover faade performance, making the design and procurement of the building envelope a highly technical and complex process as yet one that is still immensely creative.Various architects have presented performance-based prototypes as technological, social, and utopian solutions for the problems we face. Here are two examplesAdaptive faade Fluidic muscle technology Prof Ir Kas Oosterhuis 2003This was a competition, its aim being to come up with an innovative idea to create a faade that has flexibility that will enable the occupants to have total control of the light levels in their spry area, rather than have a centralised controller. Currently most solar shading devices have no facility for localised control and the livelong faade has to change a t once and can usually only be set to fully open or fully closed. This system allows the building users in any part of the building to set their own preferred light levels. The muscles are made of silicon coated polymeric amide rubber with brand name valves at each end, the shades are inflatable cushions made of polyester coated with hypalon and the whole assembly is joined by steel fixings. The structure is very lightweight meaning easy attachment to real buildings with little disruption. It can therefore be used to enhance the aesthetics of a mundane building. The facade brings attention to the building by the way it moves, it makes the building appear as if its alive, as the skin pulsates and opens.Edge monkeys (theoretical idea) Stephen A. puke and Will Thorne (British architect-academics)In an article published in the cyber journal Technoetic liberal arts Stephen A. Gage and Will Thorne describe a hypothetical fleet of small robots they call edge monkeys. Their function wo uld be to patrol building facades, regulating energy usage and indoor conditions. Basic duties include closing ignored windows, checking thermostats, and adjusting blinds. But the machines would also gesture meaningfully to internal occupants when building users are clearly wasting energy. This sci-fi sounding scheme crystallizes the widespread concern informing many recent architectural projects.Today, activating a buildings skin is in fashion. From the robotecture labs at top architecture schools to interactive art installations. Aesthetics and technology are converging in unlikely places. Nonetheless, the mainstream drivers for interactive envelopes are sustainability and unappeasable energy codes.Conclusion-At the conclusion of this review, I have gained an appreciation and better understanding of this new trend towards intelligent faades. Although it is somewhat difficult to purpose this study, primarily because the outcome really depends on individual interpretations and t aste. By study the views and opinions of more than one person, I feel an honest result has been achieved. in time due to the lack of commonly accepted methods and relevant supporting entropy for technology, the assessment of the overall performance of the intelligent facades cannot be carried out. It remains difficult, if not impossible, to carry out a fair comparison between different case studies in terms of intelligence. The different examples show that there isnt only one intelligent faade system but rather that depending on the case in order it is an individual solution according to the emplacement and utilization of the building. As a result it proves difficult to compare the case studies in this report. However looking at them individually the environmental info and statistics collected all point to succesfull levels achieved. The facades seem to be doing their job by reacting intelligently to the climate and impoving internal conditions while still cutting energy consum ption. The conclusion reached is that with the combination of these three elements new technology, innovative materials and very earnest design, highly efficient intelligent skins can still be aesthetically pleasing. But do technically innovative buildings always come in such stylish packages?What twenty years ago was perceived as clumsy and unattractive eco-buildings and deterred architects from a design perspective is today an aesthetically interesting and multi faceted solution. In the design of new buildings, the sustainability aspect is particularly popular and the faade returns to its initial purpose of representation bold, transparent and sustainable architecture is implemented with minimal conflict as a prevalent rule. Another thought is that intelligent facades are possibly perceived as being visually attractive because of their environmental advantages in a world where being green is in vogue. Or more philosophically, people are attracted to facades with moving parts b ecause motion seems to herald change.Michael Fox an architect and robotics serious predicted Architectural environments will be increasingly smart and responsive and assailable of complex behaviours. But one must question whether such calls have been realized? And what is needed to push the idea forward and turn the promise of extraordinarily intelligent faades into a reality? Steps need to be taken to develop these products quickly. We are in the midst of global climate change, the way we think is changing and the way in which buildings are designed and made must also change. Adaptive, intelligent environmental strategies offer a critical contribution to the broad ambition of reversing environmental damage.Intelligent facades will, one day in the near future become a sine qua non/commonplace and that in time may hinder the obvious aesthetic merit of exemplar buildings like the ones shown in this report.
