Does papercrete fulfil the increased needs of a faรงade cladding technology? Papercrete is an experimental material which replaces an amount of cement with paper in the normal concrete mix. The total weight, the cost and the CO2 emissions during production are reduced. The research was material based, and aimed to define the limiting properties and set the main design principles. Results showed that papercrete meet most of the faรงade cladding systems requirements. It is a lightweight material (7 times lighter than concrete) with good heat and acoustic insulation properties and big variety on shapes, colours and textures. Papercrete is a properties limited material. These properties will define whether if can be used as a faรงade cladding material or not. Adding reinforcement (fibres or metal mesh in the mesh) to improve the mechanical properties, changing the manufacture process (use less water-ovens) to minimize the drying period and increase the strength and prefabricating the panels in a controlled environment and moving them in situ when needed are the first steps towards standardizing the process and improving the quality. Papercrete is a property limited, material. There are significant challenges going into business with papercrete but also opportunities. Deep knowledge in material properties and long term liability, advance in processing and building aspects, in combination with future material technology, will bring papercrete closer to standardization. Getting a building permit will become easier, will attract more investments, and eventually papercrete will be commercially accepted. The project was divided in material research and design

Summary: A multipurpose tram shelter. A 4m long stripe (where all the uses are hidden) creates a rectangular space. During day time the stripe acts auxiliary to the tram stop uses. The outer skin is closed creating an enclosed space. After the last tram route, the skin opens and the space converts to an open public area.

Summary: Design of a technically innovative facade scenario for an office room. This room was manufactured and built down the Bt lab at Civil engineering It was worked out from the conceptual phase all the way through to the definitive design. Several computer programs were used to model/test aspects of the design, structural tension and building physics, as well as of the characteristics of materials and production techniques.

thesis football stadium - public urban area 5th year 2008

supervisor: c.panigiris, m. vrontissi

m.kokkinos poRtfolio

Accessible roof

Summary: The thesis is a research in the coexistence of a football ground in an urban area. The site is on Alexandras avenue where the present day Panathinaikos stadium is located. The stadium has not been used because the massive gathering of people at specific intervals creates problems in the accessibility of the city center. The size (equivalent to four big street blocks) and the periodic use (4 hours every two weeks) The austere exterior facade hinders the continuity of the urban web, impeding access and crossing, it is a visual obstruction. The aim is to solve the contradiction between a closed ground which blocks access to and the view of the Lycabetus hill and the construction of a stadium/public area/gateway to the hill. The aim is to keep the football field in the city centre and that becomes feasible if the following steps are taken: 1 Strong, end- to- end access points are constructed on ground level. 2 The interior structure is available for use by the city for sports and recreation. 3 The ground is connected directly to the metro station. 4 The bleachers on the Lycabetus hill side are gapped according to the topography which reaches the level of the football field. 5 Along Alexandras avenue, at the height of 35m, public use areas are constructed (library, restaurant, cafeterias,) and also VIP areas with a panoramic view of the city. 6 The section of the bleachers is designed in such a way as to allow immediate access to them and optimum visual penetration.

research project: paperban 5th year 2008

Summary: The lecture is about the Japanese architect Shigeru Ban and his works made of paper. The paper architecture has its roots in the Japanese tradition. After the second half of the 20th century, paper has been used in a wide range of applications (insulation, furniture, doors).The paper buildings, however, were very few. After the exhibition for Aalto in 1986, where Shigeru Ban used paper tubes as separating elements and a roof for the first time, realized that a new world, free for innovative ideas and experimentation, was opened ahead. The paper tubes are made of recycled paper wound in layers around a metal bar which is then removed creating a hollow space. The number of layers i.e the width of the tube and the hole inside affect the resistance in pressure. Shigeru Ban maximizing the advantages and the technical characteristics of the paper, started his work in 1989 –Paper House, Nagoya Japan, and is permitted to use it as body structure in 1995 for a house he built for himself-Paper House Yamanashi in Japan. Through experimentation, he constantly develops his material devising new ways to seal , fire proof and reinforce the joints. By the end of 2006 he had completed 22 paper constructions which vary in terms of cost, conditions location and use making the task of classifying them very difficult. He designs both temporary and permanent constructions without changing the way he uses the tubes. I chose to classify his works on the basis of their structure and form. Then, I analyse three evidential of his work in details regarding the design, the method of construction and the occasional limitations. The structure, the final designs, the materials used and the knots biding the tubes are also analysed.

Team [K]-onstruction is a working group investigating the material and structural characteristics of the architectural artifact. Workshops are organized towards the customdesign and full-scale construction of small-scale architectural structures, focusing on the continuum and the complexities of the design process. Experimentation in applied research is nurtured through the merging of professional practice within an academic perspective, in practice-based modules fostering teamwork and multi-disciplinarity. 1.Construction-Assembly 2.Joinery detail 3.Final mockup 4.Cutting wood

Tensegrity describes a closed structural system composed of a set of three or more elongate compression struts within a network of tension tendons, the combined parts mutually supportive in such a way that the struts do not touch one another, but press outwardly against nodal points in the tension network to form a firm, triangulated, prestressed, tension and compression unit. During the workshop 7 structures were complete.
