Compare Among Methods for Re-Habitation Damaged Concrete Beams-Ferrocement, Steel, FCRP and Nano-Materials Sections

The complicated and costly of concrete structures as well as the exposure to risk, owing to several factors such as ecological, design and construction, has resulted in a wide variety of methods for residential concrete structures, such as ferrocement sections technology, steel section technology, FCRP technology, and nano-material technologies. In this article the four approaches employed for rehabilitation of damaged concrete were compared. The questionnaire is given to 100 construction engineers and project management professionals to determine their preferred methods and advise them on their strength, effort, time and cost. To confirm the results, the researcher conducted an experiment to compare among these methods. research result, recommendations for future research, and conclusions were discussed in detail.

ENVIRONMENTAL TENDENCIES FOR THE ARCHITECTURE FORMATION OF MODERN EXHIBITION AND EDUCATIONAL STRUCTURES

The ecological tendencies of forming of architecture of modern exhibition and educational buildings for revealing of ways of creation of ecological design decisions of this type of structures and expedient use of leading principles of eco-design of interior spaces are highlighted. The analysis of architectural decisions of existing ecological exhibition and educational institutions is carried out. It is revealed that the main task in designing buildings of this type is to ensure speed, ease and accessibility of human perception of information to initiate the process of thinking, analyzing and invoking positive feelings, as well as ensuring the predicted impact of contemporary art on the subconscious, while creating eco-safety of visitors and environment. This is achieved through the rational design of the building's multifunctionality, the use of environmentally friendly materials for construction and decoration, energy conservation, the use of alternative sources of energy, energy-saving and advanced technologies, environmental waste management, efficient use of natural lighting, design and phyto design, the location of the building on the site, to create an unbroken connection between the interior and exterior space, etc.

A New Zealand Superblock: Smart Planned Development

<p>Wellington city’s forecast, for the period 2011-31, is that the urban population will increase by 20,000 residents, including 60% increased demand for rental properties. This research investigation focuses on sustainable means of increasing housing density in the face of ever-increasing urban sprawl. The research proposes that Wellington City Council’s Smart Capital (2010) initiatives for urban expansion infrastructure projects—with aims to attain progressive urban growth with desirable characteristics—are good on some levels, but remedies such as infill and intensification that encroach on urban green spaces are unsustainable. The encroachments caused by urban sprawl can damage both environmental design characteristics and, the well-being of inhabitants. The thesis proposes that smart planned development (SPD) principles, when sustainably maintained, can be an effective alternative urbanisation method to WCC’s Smart Capital propositions. This investigation proposes a theoretical formulation supporting the construction of superblocks within New Zealand, using SPD as a process. For example, Lincolnshire Farm in Wellington is a site exemplar whose proximity and size would permit the city to construct alternative spatial configurations, in the form of a modified superblock for the New Zealand context. The Modern Movement reflected on the viability of superblocks of urban housing for population growth. Historically, these superblocks when built were problematic due to the detrimental attributes of automobiles, densities, and metropolitan expansions. This thesis proposes ways to mitigate these difficulties by merging relevant components of three environmental approaches: ‘Ecological Design’ principles by Sim Van der Ryn; ‘Green Urbanism’ principles by Steffen Lehmann; and framework of ‘Green Transit Oriented Development’ proposed by Robert Cervero and Catherine Sullivan. Once relevant aspects of these principles are assimilated, the research examines them within the context of Kevin Lynch’s principles for a good city form (GCF), to help contribute to the development of new sustainable criteria for superblocks in New Zealand. As case studies, the comparative methodology of this investigation evaluates the achievements of Woodberry Down in London, Discovery Bay in Hong Kong, and Linked Hybrid in Beijing, and Hobsonville Point in Auckland.</p>

Ecological design ideas of large-scale public buildings: review of Russian Botanical Garden greenhouses ecological design

With the rapid development of cities around the world, the concept of ecological design of large-scale public buildings has gradually come to the attention of the public. One of the main problems is the possibility of maintaining a balance between urban development, nature and man, which creates conditions for improving the environment and improving the quality of life of the population. An ecologically comfortable environment is considered today as one of the main prerequisites for the development of a particular territory. This article first gives a brief overview of scientific sources on the design of public buildings in botanical gardens, then discusses the principles of environmental design of large-scale public buildings and, finally, review the ideas of environmental design of greenhouse buildings in Russian botanical gardens from two aspects of form and content. The relevance of the work is ensured by the fact that botanical gardens occupy an important place in any city and it is necessary to understand how to update the garden space, how to respond to the new requirements of society and by what means to attract more visitors. Based on the analysis of various examples, the author notes the existing problems of construction of large-scale public buildings of eco-friendly design in Russian botanical gardens, and also comes to the conclusion that the landscape architecture of Western Europe and the experience of Western engineers in eco-friendly construction has a great influence on the image of modern Russian botanical gardens.

Ecological Design Strategies and Theory for Urban Parks in Seoul, 1990s–Present

This study explores the characteristics of and changes in Korean landscape architects’ attitudes toward ecological design strategies and theories over the last three decades. Methodologically, this study includes a literature review and incorporates data from case studies and site visits. It discusses Seoul-specific contexts regarding environmental conditions, urban morphology, administrative agency, and design theory and practice. It redefines ecological parks, expanding their scope using physical and non-physical ecological processes. Considering this redefinition, this study categorizes the five main attitudes of contemporary Korean landscape architects towards ecological design: providing wildlife habitat, constructing aesthetic experiences, the phasing strategy, developing environmental learning programs, and designers’ metaphoric expression. Through these attitudes, this study chronologically explores gradual and constant changes in design strategies and the discourse on ecological design. Specifically, in the 1990s, landscape architects emphasized the representation of ecosystems by constructing wildlife habitats. In the early 2000s, ecological parks were artistically designed as urban parks by reusing post-industrial landscapes. Around the 2010s, landscape architects developed resilient and adaptive design strategies to flexibly respond to uncertain changes in natural and urban ecological circumstances. Since the 2010s, landscape architects have continually expanded the scope of ecology to cover physical, non-physical, urban, and social infrastructures, including public transportation, as well as political, social, and cultural structures and virtual and augmented landscapes. This study can contribute to the field literature while adding a valuable overview of the understudied Korean context.

Ecological Design and Construction Strategies through Life Cycle Assessment of Carbon Budget for Urban Parks in Korea

Although urban parks sequester carbon by vegetation growth, they emit carbon due to materials production, transport, construction, management, demolition, and disposal throughout their life cycle. This study estimated the carbon budget of urban parks over their life cycle according to land cover type and explored ecological design and construction strategies to maximize carbon reduction. After setting up the scope of the life cycle, the energy and material used for each stage were analyzed on the basis of field survey, design and construction details, and literature review of 30 study parks. The net carbon uptake per unit of park area averaged 8.51 kg/m2, with urban parks playing an important role as a source of carbon uptake to mitigate the climate change. This study suggested ecological design and construction strategies including the expansion of tree planting spaces through the minimization of grass and impervious areas, the minimization of changes to existing topography, and the utilization of local materials. As a result of applying these strategies to study parks, the net carbon uptake increased approximately 9.2 times. These study results are expected to be useful as information for the implementation of carbon-neutral policies and greenspace establishment projects.
