Origami folded surfaces: kinetic system behind the folding

“Today’s intensification of social and urban change, coupled with the responsibility of issues of sustainability, amplifies the demand for interactive architectural solutions. In the context of architectural need, the attribute of being able to adapt to changing needs is paramount in contemporary society.” (Fox and Kemp, 2009). Since the 1960’s that Architecture is progressively more merged with several other fields. Fields like biology, robotics, mechanics, electronics, parametric design, digital fabrication and so many others get to be together through Architecture. It is getting easier and more feasible for the designer to create buildings that are kinetic, interactive and/or responsive in order to communicate with users, enhance the building’s performance in response to changing atmospheric conditions and even transform its own geometry to reconfigure spaces as a functional answer to changing demands. The use of kinetic buildings, or kinetic elements in a building is becoming a natural response to concrete architecture solutions in order to make buildings “intelligent” and “alive” so they can meet the actual demands of users and use the technological means that are currently available. On this sense this paper focuses specifically on kinetic architectural systems through the use of Rigid Origami Surfaces. Their geometry gives them elastic capacities and is versatile enough to be used in a wide set of systems.info:eu-repo/semantics/publishedVersio

KINE[SIS]TEM'17 From Nature to Architectural Matter

Kine[SiS]tem – From Kinesis + System. Kinesis is a non-linear movement or activity of an organism in response to a stimulus. A system is a set of interacting and interdependent agents forming a complex whole, delineated by its spatial and temporal boundaries, influenced by its environment. How can architectural systems moderate the external environment to enhance comfort conditions in a simple, sustainable and smart way? This is the starting question for the Kine[SiS]tem’17 – From Nature to Architectural Matter International Conference. For decades, architectural design was developed despite (and not with) the climate, based on mechanical heating and cooling. Today, the argument for net zero energy buildings needs very effective strategies to reduce energy requirements. The challenge ahead requires design processes that are built upon consolidated knowledge, make use of advanced technologies and are inspired by nature. These design processes should lead to responsive smart systems that deliver the best performance in each specific design scenario. To control solar radiation is one key factor in low-energy thermal comfort. Computational-controlled sensor-based kinetic surfaces are one of the possible answers to control solar energy in an effective way, within the scope of contradictory objectives throughout the year.FC

Interaction with a kinetic folded surface

Kinetic systems offers new perspectives and design innovation in research and practice. These systems have been used by architects as an approach that embeds computation intelligence to create flexible and adaptable architectural spaces according to users changing needs and desires as a way to respond to an increasingly technological society. The presented research attempts to answer to this question based on the results of a multidisciplinary on-going work developed at digital fabrication laboratory Vitruvius Fablab-IUL in Lisbon. The main goal is to explore the transformation of the shape of a construction by mechanisms which allow adaptation either to environmental conditions or to the needs of the user. This paper reports the initial development of a kinetic system based on an origami foldable surface actuated by a user. The user can manipulate a small scale model of the surface and evaluate at all times if it is achieving the desired geometryinfo:eu-repo/semantics/publishedVersio

Kinetic origami surfaces: from simulation to fabrication

On nowadays social, technological and economic context everything changes constantly so there is the persistent need to adapt at all levels. This research defends that Architecture should do the same through the use of kinetic and interactive buildings, or elements in a building. These elements should allow the building to adapt to changing needs and conditions. This article describes the current state of an ongoing research that proposes the use of kinetic Rigid Origami foldable surfaces to be used as roofs for spaces with big spans and the practical contribution that the Design Studio Surfaces INPLAY has brought to it

KOS - kinetic origami surface

In an increasingly technological, informed and demanding society Architecture should be able to answer to its space require-ments using materials and technological resources that today has at its service. Kinetic systems have been used by architects as an approach that embeds computation intelligence to create flexible and adaptable architectural spaces according to users’ changing needs and desires. This paper describes one possible way of exploring kinetic systems to develop a foldable surface with geometric patterns based on the rules of rigid origami. This surface aims to take advantage of the elastic ca-pacities given to a planar material by its folding. After folding the sur-face can assume different forms in order to create a range of spatial configurations ordered by a user through a remote control.info:eu-repo/semantics/publishedVersio

Interactive design for everyone: from folding to programing

In our society today technology is already part of the normal day life, but it is something still not available to everyone. There are some that cannot reach it the same way as others do, either because of less resources or because learning can be quite a challenge. After the development of several works with a partnership between VFabLab and EPIS that involved basic level schools, the workshop that will be explained, describes how students in special learning programs get in touch with subjects like digital fabrication; interactive architecture, design, and programing

Origami tesselations: folding algorithms from local to global

Rigid Origami folding surfaces have very interesting qualities for Architecture and Engi-neering for their geometric, structural and elastic qualities. The ability to turn a flat element, isotropic, without any structural capacity, into a self-supporting element through folds in the material opens the door to a multitude of uses. Besides that the intrinsic geometry of the crease pattern may allow the surface to assume doubly curved forms while the flat element, before the folding, could never do it without the deformation of the material. (Schenk, 2011) (Demaine, 2011). The main objective of this PhD research is to reach a workflow from the definition of the geometry of the flat foldable surfaces to their implementation on a construction site. This paper will address mainly the steps taken to the parameterization of the Rigid Origami ge-ometries. We intend to establish a method to simulate the folding of regular crease pat-terns (tessellations) by understanding the geometric operations on the smallest set of faces (local) that can be reproduced to simulate the whole group (global).info:eu-repo/semantics/publishedVersio

Mosquito surveillance for prevention and control of emerging mosquito-borne diseases in Portugal - 2008-2014

Mosquito surveillance in Europe is essential for early detection of invasive species with public health importance and prevention and control of emerging pathogens. In Portugal, a vector surveillance national program-REVIVE (REde de VIgilância de VEctores)-has been operating since 2008 under the custody of Portuguese Ministry of Health. The REVIVE is responsible for the nationwide surveillance of hematophagous arthropods. Surveillance for West Nile virus (WNV) and other flaviviruses in adult mosquitoes is continuously performed. Adult mosquitoes-collected mainly with Centre for Disease Control light traps baited with CO2-and larvae were systematically collected from a wide range of habitats in 20 subregions (NUTS III). Around 500,000 mosquitoes were trapped in more than 3,000 trap nights and 3,500 positive larvae surveys, in which 24 species were recorded. The viral activity detected in mosquito populations in these years has been limited to insect specific flaviviruses (ISFs) non-pathogenic to humans. Rather than emergency response, REVIVE allows timely detection of changes in abundance and species diversity providing valuable knowledge to health authorities, which may take control measures of vector populations reducing its impact on public health. This work aims to present the REVIVE operation and to expose data regarding mosquito species composition and detected ISFs.This work was partially supported by the Fundação para a Ciência e Tecnologia (FCT) under the project “New arboviruses isolated in Portugal. Risk assessment and public health application” (PTDC/SAU-SAP/119199/2010)
