    Digital architecture and designing architecture space and ITS effect on future life strategy

    Get PDF
    Technological advancements have altered nearly every aspect of individuals’ existence and operation in society. When technologies develop, architecture evolves as well: the architectural techniques change, as does the architectural outcome. The digital revolution reflected on architecture, as did other scientific and life fields. Its impact on the work and architectural space was evident. The architectural production became not limited to designing in traditional ways and directing it as computer drawings. Still, it went beyond that, as the designs produced became the product of an intelligent design process directly influenced by the digital community in general. Architectural space has gone through many developments throughout history influenced by technology and building techniques on the one hand and by functional and environmental issues and human factors on the other hand. The architectural space appeared in the form of a living being that grows over time and is influenced by all the variables of the times and expresses the personality of its inhabitants. If the architect determines space and its composition according to human needs, it is also influenced by the imagination of architecture and its vision of freedom. Therefore, the problem of research was determined by "the lack of a clear vision of the development of architectural space and how it is affected by the digital revolution," where the research aims to identify indicators of the development of architectural space in light of digital development and how architectural thought deals with the changes brought about by information technology, and how it was expressed in the form of areas that meet the needs of users, which in turn changed in terms of sensory needs or physical needs. The research thus assumed "the existence of mechanisms, strategies, levels, and degrees of digital use within the process of designing architectural and urban space to generate digital space," and to achieve this will begin to learn about the evolution of space and what it is over time with a quick presentation of the most prominent developments in the architectural and urban space, especially in the recent years, to a final formulation of the characteristics of knowledge of digital areas

    Previous design efforts of a cost effective and reliable regenerative life support system (RLSS) provided the foundation for the characterization of organisms or 'biological processors' in engineering terms and a methodology was developed for their integration into an engineered ecological LSS in order to minimize the mass flow imbalances between consumers and producers. These techniques for the design and the evaluation of bioregenerative LSS have now been integrated into a lunar base reference mission, emphasizing the phased implementation of components of such a BLSS. In parallel, a designers handbook was compiled from knowledge and experience gained during past design projects to aid in the design and planning of future space missions requiring advanced RLSS technologies. The lunar base reference mission addresses in particular the phased implementation and integration of BLS parts and includes the resulting infrastructure burdens and needs such as mass, power, volume, and structural requirements of the LSS. Also, operational aspects such as manpower requirements and the possible need and application of 'robotics' were addressed

    Sustainable consumption: towards action and impact. : International scientific conference November 6th-8th 2011, Hamburg - European Green Capital 2011, Germany: abstract volume

    Get PDF
    This volume contains the abstracts of all oral and poster presentations of the international scientific conference „Sustainable Consumption – Towards Action and Impact“ held in Hamburg (Germany) on November 6th-8th 2011. This unique conference aims to promote a comprehensive academic discourse on issues concerning sustainable consumption and brings together scholars from a wide range of academic disciplines. In modern societies, private consumption is a multifaceted and ambivalent phenomenon: it is a ubiquitous social practice and an economic driving force, yet at the same time, its consequences are in conflict with important social and environmental sustainability goals. Finding paths towards “sustainable consumption” has therefore become a major political issue. In order to properly understand the challenge of “sustainable consumption”, identify unsustainable patterns of consumption and bring forward the necessary innovations, a collaborative effort of researchers from different disciplines is needed

    To achieve truly low cost system design with direct evolution for inorbit shuttle resupply, a modular building block approach has been adopted. The heart of the modular building block concept lies in the ability to use a common set of nonoptimized subsystems in such a way that a wide variety of missions can be flown with no detrimental impact on performance. By standardizing the mechanical configurations and electrical interfaces of the subsystem modules, and by designing each of them to be structurally and thermally independent entities, it is possible to cluster these building blocks or modules about an instrument system so as to adequately perform the mission without the need for subsystem redevelopments for each mission. This system concept offers the following capabilities: (1) the ability to launch and orbit the observatory by either the Delta, the Titan, or the space shuttle. (2) the ability to completely reconfigure the spacecraft subsystems for different launch vehicles, and (3) the ability to perform in-orbit resupply and/or emergency retrieval of the observatory

    Space Station Freedom automation and robotics: An assessment of the potential for increased productivity

    This report presents the results of a study performed in support of the Space Station Freedom Advanced Development Program, under the sponsorship of the Space Station Engineering (Code MT), Office of Space Flight. The study consisted of the collection, compilation, and analysis of lessons learned, crew time requirements, and other factors influencing the application of advanced automation and robotics, with emphasis on potential improvements in productivity. The lessons learned data collected were based primarily on Skylab, Spacelab, and other Space Shuttle experiences, consisting principally of interviews with current and former crew members and other NASA personnel with relevant experience. The objectives of this report are to present a summary of this data and its analysis, and to present conclusions regarding promising areas for the application of advanced automation and robotics technology to the Space Station Freedom and the potential benefits in terms of increased productivity. In this study, primary emphasis was placed on advanced automation technology because of its fairly extensive utilization within private industry including the aerospace sector. In contrast, other than the Remote Manipulator System (RMS), there has been relatively limited experience with advanced robotics technology applicable to the Space Station. This report should be used as a guide and is not intended to be used as a substitute for official Astronaut Office crew positions on specific issues

    Thesis (Master)--İzmir Institute of Technology, Architecture, İzmir, 2003Includes bibliographical references (leaves: 169-171)Text in English; Abstract: Turkish and Englishxiii, 174 leavesIn the line with the increasing energy demand, there have been many investigations related with the conservation of energy used in buildings. The systems and materials used in buildings have an important role in consumption of energy. Transparent materials and the systems occupies transparent materials contributes this consumption in positive and negative way due to their design and properties. Nevertheless, the transparent materials used in buildings as glazing have importance in order to increase comfort, decrease cost and environmental harm.This study aims to investigate a contemporary construction system; ETFE foil pillow system, which is also known as, Inflatable Pillow System made of ETFE Foil. In the scope of the study, pneumatic pillow system investigated in detail and its performance evaluated due to environmental control criteria, which can be compared with other conventional glass glazing products. The study also involves cost analysis and brief knowledge about contemporary cases that have been completely or partially constructed with this system. The increase in the amount of transparent surfaces in contemporary buildings, pointed out that the conventional glazing system are no more appropriate. Therefore, in specific cases, usage of conventional glass glazing systems results as a cost increase and loss of comfort. The alternatives of the conventional glazing systems don.t have appropriate performance or don.t meet the need of the consumer. Inflatable ETFE foil pillows have better optical properties than glass glazing systems. Generally, thermal properties of this system equal to the advanced double-glazing. Light and heat transmission values vary by changing the foil type and number of layer. Low sound reduction index can be an obstacle or a chance for designers that should be given attention in design phase. The pillow system that relatively provides fire and earthquake protection is also lightweight and flexible. Thus, includes many criteria that are expected in contemporary constructions. The inflatable pillow system made of ETFE foil can be considered as a safe construction method due to mechanical properties of the system and the membrane material that is used as pillows. System reduces operational and maintenance cost for the building. Considerable amount of expenses for lighting and heating can also be reduced by the usage of the pillow system. The lightweight nature of the pillow system affects the construction of the whole building, which also results as a cost reduction.Pillow system is commonly used for greenhouses and botanical gardens and also used for sports and leisure halls as well as institutions ands museums. Addition to its usage as a skylight or façade cover, pillow system can be used as a total envelope that covers the whole construction underneath.As a result, this study investigates ETFE foil pillows and their environmental control properties against conventional glass glazing systems. The results are evaluated in the line with the information gained. The advantages and disadvantages of the system as a glazing are given in detail. Although it.s not expected that ETFE pillow system totally be replaced with the conventional glass glazing system, it constitutes an alternative glazing system in specific cases.Keywords: pillow system, pneumatic membrane, glazing, ETFE foil, glass, fluoropolymer, environmental control criteria
