[Method]The GM (1, 1) forecasting model was set up according to statistics of public green area per capita in Xi’an City during 1996 and 2005, on this basis, the development trend of green area per capita in Xi’an City until 2015 were analyzed in case of no any changing factors or conditions. [Result]Grey forecasting model was established as, (t = 0, 1, …, n); model parameters as a = - 0.031 71, u = 4.139 17. After residual error test and posterior-variance-test, the precision of this model is proved fairly good. [Conclusions]According to this model, public green area per capita in Xi’an City will achieve 7.66 m2 by 2015, which is still far away from the livable city index (16 m2 per capita) and should be paid more attention by the local government, the construction of urban green areas should be further enhanced, more vegetations should be cultivated so as to improve the urban green coverage ratio.展开更多

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.展开更多

Researcher has developed a number of assumptions that helps to resolve the research problems, which includes the application of the indoor environmental quality and will highlight the required design standards of it to provide a healthy environment to the houses and chosen AREE （Aqaba residence energy efficiency） as a case study. The theoretical part goes through a brief study to definition of the required design standards which includes eight kinds of issues： indoor environmental quality intents, control of environmental tobacco smoke, control of chemicals contaminants, design well ventilated buildings, provide daylight/view, energy efficient lighting, thermal comfort, consider acoustics and its uses in all the elements of internal spaces. Than we going through the uses of these requirements by using descriptive analytical approach, we chose one case study （AREE）. To analyze the uses of their requirements of the indoor environmental quality and we also collect the information about this house from the owner of the AREE, then draw conclusions and list of references.展开更多

This involves social, cultural,political, and regulatory dynamics. Critically using transition theory conceptualization of a world of dynamics, the paper reviews institutional theory and actor network approaches in an attempt to better account for contemporary developments in Europe, encompassing EU reforms as well as multiple competing concepts. The emergence of ＂passive houses＂ in Denmark is used as a case of transition dynamics. The concept was developed in Germany and imported into Denmark. It is a technological niche, encompassing technologies, players, improvisation, and early customers. Passive houses have entered into fierce competition with other future institutions such as LEED （Leadership in Energy and Environmental Design）, DGNB （German Sustainable Building Council）/green building council, and active houses. Passive houses were at the outset a well-developed upcoming institution with design principles, software, certification and numerous reference buildings, strong enough to be a challenger institution. They are promoted by a characteristic alliance of architects, consulting engineers, a few clients, and an architect school, whereas the other concepts exhibit their specific actor alliances. Yet passive houses experience barriers such as the reputation of being expensive and non-user friendly, and are currently surpassed by the other concepts.展开更多
