The solutions for the development so far have typically been compact villas located on abruptly leveled gardens, irrespective of the complex topographical condition of their sites. The house is a conscious exercise in developing an alternative domestic environment to the surrounding villas of the new suburban neighborhood. Project team: Diego Repiso, Jennifer Chuong, Kaizen Chen, Jon AguirreĬonstruction managment: In collaboration with Satie Arquitectos S.L. The membrane between the bands need be tested through metal origami, fabric, and other hybrid methods to find optimal folding mechanism.Architects: asensio_mah & J.M.Aguirre Aldaz The engineering of intentionally applied weakening building components will be also tested. As for building, the snapping bands will be explored with patterned metals, plastics, and/or wood veneers. Foldable car window shades also use the property of snapping. This elastic instability is already utilized in kids’ products such as Rubber ball poppers and Snap Bracelets. Without complicated maintenance, users can participate in the dynamic movement of the building envelope for play, fun, and energy saving. Traditionally, unstable movement within the building construction is considered as an undesirable occurrence but, the Snapping Facade aims to harness the characteristics of elastic instability by applying it as an opening and closing mechanism using the embedded energy within the materials. The prototype explores using weakening-induced bands tied within the elastic threshold which, produce “snap” deformation with minimal stimulus.

Snapping Facade suggests an alternative approach for the design of dynamic facade systems that use a “snapping-induced motion” to open and close apertures, providing shading for the building. Compared to the mechanical dynamic shading, these glass systems can efficiently provide substantial energy saving with low cost, however the façade design becomes independent gears added to the irrelevant building design. Other Smart glass such as Suspended Particle Devices can provide the similar function and form-changing polymer sheet can be installed in the glazing units. For instance, electrochromic glass uses voltage to change light transmission property. Built dynamic façade systems such as Abu-Dhabi Investment Council Headquarters by AHR Architects, dynamic roof shading at Aldar Central Market by Foster + Partners, Hoberman Associates and Adaptive Building Initiative and Kiefer Technic Showroom by Giselbrecht+Partner are based on mechanical actuators which need additional energy consumption to operate and require complex maintenance.Īdvances in material science and engineering have also contributed to the mission of smarter building envelope. The increasing need for high performance buildings and advancements in manufacturing industries have facilitated the design of dynamic building envelopes to replace traditional, uninspiring shading controls. However, in the United States, buildings account for 41% of energy use and 38% of CO2 emissions. The reflection and refraction of glass represents the dynamic, bustling activities of our cities while diverse lifestyles and programmatic functions are expressed through the façade of our buildings. Advances in the high performance glass industry have made the use of glass ubiquitous. The building envelope controls heat gain and loss, allows views for visual comfort, and provides natural light. Snapping Facade explores a sustainable building envelope design strategy that utilizes elastic instability to create dynamic motion at the building envelope.ĭongsik Kim Seonjajang (intangible cultural asset)
