Abstract: Sustainable development is the indispensable composition of urban building.From the viewpoints of history,practice,as well as philosophy,actual facts ,deep analysis and discuss are carried out in this paper.Finally we come to an important conclusion that the basic gist of sustainable development in constructing urban building consists of law and rules,technology and resources.The research and analysis also tell us that the three factors above integrated together closely and developing by relying on each other are the necessary trend and the essential content.

Abstract: In terms of the poor conditions of China’s Loess Plateau region, the feasibility limited by budget and conventional resources for construction is the main challenge faced by ecologically design for local buildings. Aiming to explore a way towards an ecological architecture suited for this region, a primary school project is studied as a prototype. The methodology combining condition analyses, computer simulation experiments with TAS and field construction is involved with thermal design as the focus. Based on locally available materials and vernacular technology, a series of alternative techniques and feasible thermal design strategies for this region are carried out and further alternatively validated in construction, aiming to reach the most effectively ecological approach. By comparing with local conventional buildings, it is found that with similar construction cost the classrooms can contribute a far better ecological performance in indoor thermal comfort, energy consumption and environmental impact. It illustrates to the locals a feasible way for current local conditions, in which by selectively employing their familiar techniques and materials they can easily build themselves their most affordable and most effective ecological approaches.

Abstract: Ecological niche, biological community and the quantitative modeling problem are the focus that ecosystem concerned. But synergy, which is produced by orderly competition and effective cooperation hasn’t been fully understood and used. In order to keep sustainable development, the enterprise has to compete and cooperate with different organizations and enterprises. The article aims to optimize the relationship between real estate enterprises and try to find the best position between them. This article was started with overlap value relations, using the principle of ecological niche to discuss the competition between the real estate enterprises.

Abstract: Contemporary high-tech buildings pursue ecological design. Through the use of new technologies, new materials and advanced scientific means to solve ecological problems. By improving energy efficiency, reducing consumption of non-renewable resources, making full use of clean energy, architects create an ideal living environment.

Abstract: According to the ecological pattern of population spatial inhabitation (EPPSI), the planning of population spatial distribution shall include capacity and spatial distribution. The core connotation is that the population capacity is based on the carrying capacity of “natural-economic-social” complex system and the spatial distribution is based on “sustainable-efficient-equal” value orientation.

Abstract: This paper proceeds from the basic conceptions of systematology and cybernetics and researches ecological architecture from one new angle. The paper divides the building control system into the open-loop control system and closed-loop control system, and further researches their principles.

Abstract: Climate crisis has become the main concern of International community. China is undergoing the quick growing period of urbanization. The fast urbanization inevitably encountered a lot of problems and defects. Our carbon emission occupy more and more percentage of the whole world. To change the traditional way of constructing activity and work towards low-carbon city development mode is the most important task of China city development. From the causes of low carbon cities construction and its significance, this essay focuses on the space structure, traffic mode, land use and landscape architecture framework of constructing a low-carbon city. Low carbon urban construction planning is also presented.

Abstract: To overcome the traditional cave dwelling lacks, we have designed a green cave dwelling area with a safe structure, improved infrastructure, fluent ventilation, good light in northern Shaanxi, which inherited simple ecology in design for traditional cave, integrated modern residential building design style, and increased necessary sanitation. By compared a traditional cave, the results show that the indoor temperature 9°C between the peaks and valleys of Northern Green cave dwelling when the outside temperature difference is 24°C within the test time, and seasonal temperature wave delay time is about 12d. The thermal comfort same as the traditional cave dwellings’.

Abstract: Taking Hangzhou as an example, this paper analyzes the present situation and problems of low-rent housing exit, and developed countries and regions’ practice and experience as well. It proposes the countermeasures to optimize low-rent housing exit mechanism, including the building of information sharing mechanism, the legal system perfection and the establishment of gravity mechanism, etc.

Abstract: Practical risk purchasing management method of engineering materials is put forward by using Monte Carlo Simulation. First, the calculation method of economic order quantity is put forward based on rising price. Second, appropriate insurance inventory is calculated when material requirements is variable.
