Green Architecture for Dense Home Area Networks Based on Radio-over-Fiber with Data Aggregation Approach

The high-density population leads to crowded cities. The future city is envisaged to encompass a large-scale network with diverse applications and a massive number of interconnected heterogeneous wireless-enabled devices. Hence, green technology elements are crucial to design sustainable and future-proof network architectures. They are the solutions for spectrum scarcity, high latency, interference, energy efficiency, and scalability that occur in dense and heterogeneous wireless networks especially in the home area network （HAN）. Radio-over-fiber （ROF） is a technology candidate to provide a global view of HAN＇s activities that can be leveraged to allocate orthogonal channel communications for enabling wireless-enabled HAN devices transmission, with considering the clustered-frequency-reuse approach. Our proposed network architecture design is mainly focused on enhancing the network throughput and reducing the average network communications latency by proposing a data aggregation unit （DAU）. The performance shows that with the DAU, the average network communications latency reduces significantly while the network throughput is enhanced, compared with the existing ROF architecture without the DAU.

Environmental Strategies for Design of Sustainable Buildings in Technique of Green Eco-Architecture

Architecture is defined as a symbiosis of function, aesthetics, technology and economics. This paper introduces the concept of development of technology in architecture for a sustainable society. The concept is based on a systemic link building-climate-energy. The scientific analysis of this link allows us to define three technical levels of modern architecture. The lowest level is represented by low energy architecture that gives priority to the element of energy. Climate is defined only by physical parameters here. It is characterized by the production of emissions that deplete the Biocapacity of the Earth. Higher level of architecture is represented by green architecture which gives equal priority to both energy and ecology. Climate is defined by physical and chemical parameters here. It is characterized by the tendency of reduction of emissions production and move towards environmentally clean energy, material and water sources. Sustainable architecture represents the target program of development of human settlements in the interaction of society-energy-ecology. It is characterized by the balance of categories nature-man-technology and by minimizing the emissions production to the extent of their coverage by the Earth＇s ecosystems. This paper introduces design strategy for green building. The basic structure of the strategy defines, and internal structure of the strategy emphasizes, principles and concepts of green buildings. In this strategy, the vital role is played by renewable energy sources as a production technology of the capital provided to man by nature.

Is Greening the Building Envelope a Sustainable Design Practice？

Nowadays, the number of products and also of architectural projects, qualified as ＂sustainable＂, is ever more growing. Following this trend, architectural design may exploit the use of （eco） materials and components to promote a project as sustainable even without considering its impact on the environment; This can be defined as architectural greenwash. This paper considers the case of green envelopes with the aim to evaluate if these can be defined as sustainable design practice. Green envelopes provide environmental advantages together with the suggestion to a green aesthetics par excellence. In fact, the integration of vegetation in urban fabric plays an important role in improving ecological and environmental conditions of （and in） cities, although systems can have a high environmental burden. This paper aims to answer the question： Is greening the building envelope a sustainable design practice？ To do so, the paper provides a literature review which includes the main research developed regarding environmental burden, benefits and LCA （life cycle assessment） calculations of green envelopes.

THE WISTER EDUCATION CENTER AND GREENHOUSE Uniting Program and Process,History and Mission,Architecture,and Sustainability on the Swarthmore College

Swarthmore College honors its Quaker principles by educating students to be responsible world citizens and through good stewardship of its land and building resources.Today this tradition of citizenship and stewardship is reflected in the College’s purchasing of sustainable power and construction choices.The new 5,200 square foot Wister Education Center and Greenhouse for The Scott Arboretum of Swarthmore College is the most recent and far-reaching green building on campus and serves as a model for integrating sustainable design with the function,mission,and architec­ture of the institution.

Reflection on Full Life Cycle Green Architectural Design of Passive Priority——Taking the Award Design of China Merchants Property 2013 Green Architectural Design Competition as an Example

In the China merchants property 2013 green architectural design competition,feature of this awardwinning program is the design method based on the principles of passive priority and comprehensive utilization of full life cycle. The passive priority can be achieved by building form derived from the simulation and analysis of wind environment,improvement of the building envelope insulation and the dehumidification of fresh air,the use of solar energy. The full life cycle utilization can be accomplished by the combination of exhibition and residents' leisure activities, and the integration with local cultural tradition, thereby improving energy efficiency and the utilization of the building.

Vertical axis wind turbine with omni-directional-guide-vane for urban high-rise buildings

A novel shrouded wind-solar hybrid renewable energy and rain water harvester with an omni-directional-guide-vane(ODGV) for urban high-rise application is introduced.The ODGV surrounds the vertical axis wind turbine(VAWT) and enhances the VAWT performance by increasing the on-coming wind speed and guiding it to an optimum flow angle before it interacts with the rotor blades.An ODGV scaled model was built and tested in the laboratory.The experimental results show that the rotational speed of the VAWT increases by about 2 times.Simulations show that the installation of the ODGV increases the torque output of a single-bladed VAWT by 206% for tip speed ratio of 0.4.The result also reveals that higher positive torque can be achieved when the blade tangential force at all radial positions is optimized.In conclusion,the ODGV improves the power output of a VAWT and this integrated design promotes the installation of wind energy systems in urban areas.

Study on the Residential Planning and Design in Subu Town of Anhui Province

The scientific research theory of Chinese contemporary art residential environment were carried out from the aspects of the people-centered and ecological environment. This study absorbed the essence of Chinese local ecological of the residential environment, for the use of contemprorary design. Through the practice of residential planning in Subu Town of Anhui Province, based on the protection of rural environment, the research completed according to local conditions and strategies for sustainable development.

Evaluation of Large-Scale Housing Projects in Terms of Their Compatibility to Criteria of Environmental Design

The design and execution of large-scale housing projects always have negative environmental impacts in terms of excessive consumption of non-renewable energy resources and environmental pollution. These negative impacts are multiplied in the case of large-scale housing projects where a large number of standardized units are implemented in a repeated manner. This proposed paper will study and evaluate the environmental impacts of large-scale housing projects according to criteria of environmental design. The case study project is Haram City that is a housing project for small low-income families. The project consists of 50,000 housing units and is located in 6th of October City, which has a hot dry desert climate that necessitates special design considerations and applications of environmental design concepts. The project will be analyzed and evaluated in terms of site layout, design of buildings, orientation, materials used, construction techniques, thermal behavior, landscaping, etc.
