Abstract: Our country is in a low carbon economy development period, this paper described the whole evaporative air cooler is based on energy conservation and environmental protection thinking of development, this paper described the development history of air cooler in energy conservation and environmental protection, the main body of the thinking of equipment design and each index assessment, in a large number of experimental data are put forward on the basis of the concept of "full evaporation", according to the requirements of the indicators and process requirements of equipment parts for detailed design of equipment, automatic control design, form the mechanical and electrical integration, energy conservation and environmental protection, automatic control, full evaporative air cooler and heat exchange equipment.

Abstract: Today in the context of contemporary rapid economic and social development many of the Chinese historic sites are being destroyed to make a way for new development, which is resulting in the abrupt disappearance of character and identity of the unique places. Nanxun historic water town is the most representative and unique water town in South of the Yangtze River. This paper analyzes the outstanding universal value of Nanxun historic water town, addresses the factors affecting the town such as development pressures, tourism pressures, and environmental pressures. It proposes the protective strategy for water towns in South of the Yangtze River, so that it can provide the useful experience for other historic sites in China.

Abstract: Surface water resources study has vital function for Lhasa and whole Tibet. TM images in 2000 and 2010, GIS and landscape ecological theory are applied to analyze the spatial distribution characteristics of Lhasas surface water resources. The results show: there are 6662 patches in 2000 and 6340 patches in 2010, which means there have disappeared 322 patches, while the area have increased 20.95km². The lakes class is the main surface water resources with 41.11% in 2000 and 41.03% in 2010. Tibetan Plateau is very sensitive to global cliamte change, espectially in water resouces. The areas of ice and glaciers, forested swamps, shrub swamps have no change. While other kinds of classs area shows increasing trend, especially rivers area, which increased 12.20 km².

Abstract: In 2006, Chinese government put forward the development of circular economy (CE) into the People's Republic of Chinas eleventh five-year plan outline on national economic and social development, thus developing CE officially became China's economic and social development strategic choice, which playing an important role in Chinas ecological civilization construction. The paper analyzed the development history and characteristics of Chinas Practice of CE, based on exploring some successful CE pilots, such as Binhai New Area, showing the huge Economic and environmental benefits, summarizing the Successful experience of Chinas developing CE.

Abstract: With the development of science and technology, rapid urbanization makes the survival of the human environment seriously polluted and destroyed. In the new century, with the issue that how to achieve the maximum saving ,to protect environment, to reduce pollution in the whole building life cycle and to make the harmonious between architecture and nature, Green building operating emerged. Vernacular architecture is an significant type of green building, this paper illustrates Seaweed House in Jiaodong of Shandong province and Oystershell Loculus in Quanzhou of Fujian province to perform a comparative study of cultural origins, building materials and ecological characteristics of the coastal green dwellings£¬in order to use the methods of vernacular architecture for reference to green building.

Abstract: As a starting point to the environmental adaptability theory, this paper elaborates the concept of adaptation and promotes the open, long-effective and combinable design method. Based on this, the experimental disaster environmental adaptable device has been invented. Also, by regarding the theory of building adjustment as a theoretical framework, the present study seeks to discover the applicability of environmentally adaptive model which can meet the need after the emergency or disasters, playing an essential part to the self-regeneration, and in addition to find other adaptative models which can run under changing environments.

Abstract: The development of economytraffic and industry have brought worse noise-pollution of city residences environment,the human residing acoustical environment quality is getting worse ,the development of green residential acoustical environment is extremely urgent .Dwelling houses sound insulation ability is one of important index of its quality. This text aim at the sound insulation problem because of light-weight wall being used at large, analyze the principle of sound insulation and optimize it ,briefly introduce the construction project of dwelling house sound insulation of light-weight wall by experiment contrast, expatiate on the technology measure of improving performance of light-weight wall.

Abstract: The Construction sector in Brazil has increased significantly, and the waste from these activities are becoming an increasing problem, thus receiving special attention, especially in recent decades, since a lot of them are deposited irregularly without proper disposal. Such waste, if not disposed properly, help environmental degradation, affecting not only the environment, but also, the quality of life. The objective of this research was to evaluate procedures that contribute to the development of sustainable management of construction waste, aiming to reduce, reuse and recycling of materials. Deploying a methodology for sorting waste more suitable for the work and for the monitoring and control suitable for final disposal, able to meet the legislation.

Abstract: Adopting prefabricated industrial manufacturing technology can save resources and materials, reduce the adverse impact of the construction waste and construction on the environment. To meet the national currently established building energy conservation and emissions reduction target, realize the whole life process of low carbon technology index, developing industrialization of prefabricated construction industry is an effective way. By analyzing the industrialized precast building lifecycle carbon emissions, all of them, and finally from the design point of low carbon control methods are put forward.

Abstract: To estimate the benefits of reuse building, this study selected 8 street-house cases from ¡§Old House, New Life reuse movement and calculated the average CO₂ emissions of rebuilding and refinishing in their life cycle. The results indicated that the average CO₂ emission is 103.14 kg-CO₂ /m2 before renovation, and 5.73 kg-CO₂ /m2 after renovation. The efficiency of CO2 emission reduction can be raised up to 60% and 70%. If the street houses extend their life span from 60 years to 90 years, the life cycle CO₂ emissions can be reduced from the original 1.89 kg-CO₂ /m²¡Eyr to 1.39 kg-CO₂ / m²¡Eyr. It's advantageous not only to make the best of old houses, but to decrease the environmental load.
