Today’s façades can provide responsive and performative envelopes that both contextually and conceptually react to their local surroundings while leading to lower carbon footprints.Īlthough as much interesting the façade could be, eventually, it comes down to the question of costing. It is not a new idea, but it is only recently that architects have started utilizing this technology in their structures and designs. The dynamic façades act as filters between the indoors and the outdoors, providing the users with appropriate shade, sunlight, ventilation and a visual union with the world in motion outside. What if a façade functions more than just an envelope of a building? The building envelope which is a part of the urban fabric that builds a city, has evolved over time, and with the help of latest technological innovations, it has become an assistive tool in the progress of Sustainable and Responsive architecture. But now with new technological innovations, what pushes its own boundary is how we make the façade more than just a static vertical architectural element. Throughout the history of architecture, the exterior of a building has only been looked at from the aesthetic viewpoint. These façades usually provide not only shading options, but also tend to harness the wind energy as well as the solar energy, helping to maintain the indoor comfort standards.
The long cushions on the southwest fill with nitrogen to block heat and filter light in 30 minutes, a beautiful, cascading nitrogen cloud responds to the rising temperature outside, replacing a conventional air conditioning system, which can account for 80 per cent of a building’s energy consumption.Responding directly to the needs of the occupants of the building, the functions, and the outdoor conditions, such façade systems use the latter to decrease the energy demand of the building to the lowest level possible. The triangular pillows on the southeast side inhale and exhale like lungs to provide sensor-controlled sun shading.

After application of voltage, the material expands, and the component flattens out.ĮTFE operable windows by Herzog and de Meuron If the supportive frame is flexible, due to the initial pre-stretching of the acrylic film, the frame bends.
As a result, after actuation the film becomes thinner and its surface area increases. First, due to the attraction of the opposing charges, the film is squeezed in the thickness direction (up to 380%), secondly, the repelling forces between equal charges on both electrodes result in a linear expansion of the film. Once the voltage in the range of several kilovolts is applied between the electrodes, the polymer changes its shape in two ways. In principle it consists of a thin layer of very elastic acrylic tape sandwiched between two electrodes. EAP is a highly attractive component for kinetic architectural applications due to its extreme flexibility, lightness, thin dimensions and smooth actuation.ĮAP is a polymer actuator that converts electrical power into mechanical force. The distinctive properties of the material should not only become a mere actuator replacement but be orchestrated for their aesthetic qualities.

The ETFE skin allows light to filter through but shades the people inside from direct sunlight, reducing UV rays by 85% Essentially the skin is a dynamic form of insulation and super energy-efficient window in one. A solar-powered automatic light sensor, that regulates sunlight and temperature for the structure, controls the skin. Inflatable Ethylene Tetra Fluoro Ethylene (ETFE) skin.
