Transparency of Real-Time Facade Performance

 

CHANGE IN DESIGN APPROACH TO THE TRANSPORT INFRASTRUCTURE PROJECTS LIKE AIRPORTS

Traditional facade systems and engineering are still taking place all over the world including multiple longtime failures mainly in performance, water penetration, air leakages, condensation, detachment of gaskets, falling down glass panels and peeling off silicone sealants are the main catastrophic failures nowadays in facades at many transport infrastructures projects. These prior failures are continuously happening especially due to customized and tailor-made facade systems in the long run- in infrastructure/commercial projects that are getting highly exposed to different atmospheres, environmental conditions and as well as high usage It has also become an issue of using the traditional methods of engineering that have not been calculated or mentioned in the codes of practice As per the author’s investigation and experience, most of these failing customized and tailor-made facade systems have been designed and engineered by using extremely traditional engineering and testing protocols as well as inappropriate value engineering methods.

REALTIME NEED
Natural and traditional elements can weaken HVAC in buildings. There is a general phenomenon that all façade experts always fight with water, solar heat gain, thermal bridge, and many climatic and environmental conditions. Realtime envelopes have become extremely advanced, incorporating new and sophisticated technologies and materials such as Kinetic / Operable screens/ Perforated screens and green walls.

Moreover, in today’s economic situation, energy consumption and savings are more important than ever. Improvement of energy efficiency in all aspects of our lives will reduce costs and CO2. emissions. Curtain Wall assemblies are more attractive nowadays than at any time in the past due to the abundant use of glass & aluminium/Various sustainable metal and living green wall systems in highly engineered facades.

GLOBALISED TRANSPORTATION HUBS
Airports

Airports are vital national resources. From a historical perspective, airport terminals are a relatively new building concept that has evolved in line with the requirements of the commercial aviation industry, which is even less than 100 years old. Airports serve a key role in the transportation of people and goods in regional, national, and international commerce. Also, this will have multiple different global elements as globalized transportation hubs will be used by different nationals from all over the world. Moreover, a globalized transportation hub can be taken as an iconic symbol of a country’s status and economic success. There is where a designer needs to present an iconic, sophisticated, and real-time façade on the infrastructure to serve all the real-time necessities.

An exterior enclosure of a transportation hub, orientation to be designed to maximize the use of daylighting and can significantly impact the value of solar heat gain of the building. Maximizing the daylight welcome to the building will drastically decrease the artificial lighting cost in heavyweight. As the innovation of façade systems drastically turns more towards kinetic facades and green wall systems (Living façades) author would like to describe the necessity of Kinetic and Living façade systems in transportation hubs in the real-time world.

KINETIC FACADES

Dynamic Facades 

A kinetic facade has its movement on the building envelope changing itself dynamically rather than being static by itself or fixed. Such a façade can also make different appearances and as well as treating different kinds of environmental and climate changes Moreover, a kinetic façade can be designed to treat wind, light, and energy.

A kinetic facade can treat its building infrastructure interior environment to be adjusted by opening air paths and light by itself from its façade surface movements. The façade can be programmed to respond to climatic/environmental factors, time, several occupancies etc. to improve performance and efficiency. The application of kinetic facades is not a new concept in reducing energy demand for lighting and space air conditioning.

For kinetic facades, the main factors in the production of effective designs are kinetic and machining solutions. Good knowledge of kinematics, movement simulation, reliability and durability are the keys to the successful implementation of kinetic facades in buildings.

Some location-specific questions to consider during the conceptual design stages include.

The solar angle, and its effect on selected materials and associated glare, is another factor in the design, specification, and installation of kinetic facades. The angles at which sunlight hits the facade elements can have a profound impact on aesthetics. For specific environments, such as airports or in confined urban settings, the glare resulting from the selection of highly reflective materials may be undesirable in other cases, where indirect light predominates, a material with higher reflectance can accentuate the kinetic activity of the facade.

All kinetic installations can produce a certain level of ambient sound under high wind conditions, and therefore, the selected system should not produce sound considered excessive for the given environment.

Performance requirements are important in every building, and they deserve more attention for kinetic facade systems. Careful analysis is needed regarding the interaction between kinetic facade elements and their associated building structure, as well as the impact of structural behaviour on system design and cost.

To study the effectiveness of kinetic systems, many computer simulationis have been carried out Analyzed and compared to estimate the benefits of four different building blocks (hanging, folding, horizontal vane, vertical vane). Each environment is different. Aspect solar thermal energy, daylighting, ventilation, power generation.

Benefits and Details

Kinetic architecture is experimenting with moving building parts, such as rotating facade elements or folding walls. The pioneers of kinetic architecture have been constructivist artists since the early 20th century. An example of the later symbiosis between kinetic art and architecture is the corner facade of an office building in Germany, designed in 1966 by the ZERO artist, Otto Piene. The centre of the outer shell is made up of faceted steel panels that form a wheel from which rods with aluminium spheres protrude.

Kinetic architecture is still associated with amazing visual effects due to the animated interface elements. An example of this was the stunning digital facade of the Mega Faces pavilion in Sochi which displays ever-changing images of visitors. Inspired by technical innovations, the functional spectrum of flexible interface elements continues to expand.

Another example is the “Bloomframe” developed by Hofman Dujardin Architects for warm summer nights in densely populated urban areas. The building’s facade displays a split window that folds into a balcony at the touch of a button in 10 seconds. Much technical research has been done on the mechanism and stability of the practical “folding balcony”.

In Sharifi-ha’s house in Tehran, entire rooms can be rotated from the facade The breakfast inn, guest room and home office can all be rotated 90 degrees. The mechanism, developed by the German company Burnat, is reminiscent of rotating stages in the theatre. In winter, semi- rectangular shapes remain within the closed facade in the hot summer months they are transformed into a loggia with stunning views Another new form of the kinetic facade is the smart building envelope: rotating elements such as slats, panels, sails, etc. react to external influences. They can be opened and closed gradually, depending on the measured value of sunlight, temperature, wind, or air freshness, providing targeted control over the incidence of light and indoor climate. They are usually driven by bevel-gear motors. This results in mobile interfaces with air conditioning functionality that can change in a playful way, either independently or computer-based, using programmable choreographies. 

Smart materials play a major role in the new kinetic architecture. The KW Westarkade property in Frankfurt am Main one of the most energy-efficient office buildings in the world is an innovative type of glass that can be designed in any shape and, thanks to high-tech coating can also be used to cover a large surface to protect from the sun. Transmitted vertical glass panels in warm, earthy tones give the building a multi-coloured crystalline beauty. It can open and close depending on the position of the sun so that the building changes its appearance in a seamless manner. The colours and materials were chosen by the architects at Sauerbruch Hutton in such a way that the new headquarters is an ambassador for the KfW Banking Group’s corporate values transparency, communication, and environmental awareness.

Over as another one of my kinetic facade experiences in India, we are now in the design and engineering stage of an upcoming commercial building in HYD Telangana with 4 levels of car-parking that is enhanced by a Zinc panel kinetic façade very similar to the parking garage of Brisbane.

Kinetic architecture is being rediscovered. Its pioneering character takes advantage of the exciting connection between functions to benefit user comfort and energy efficiency. Innovative materials and technologies become Ingenious modifiers of form and function. The designed and engineered Kinetic facade of the bulliding contains 4 levels and a vast area of 1500 50 m. The facade is covered with Zinc plates supplied by VM Zinc India with spedaily enhanced pigments with a brownish finish to make glamour the appearance.

The Zinc plates have been mounted to a backer steel tube structure with articulated bolting to release certain degrees of movement to have the facade dynamically moving Facade h now completely operational, and you may see its moving effect like ocean waves due to the wind.
