Abstract: Water-recovery is very useful for ease water shortages in our country cities. But this engineering’s investment is huge and capital pay back is very long. This type of environmental engineering depends on the government investment primarily, but now financial only from the government already cannot satisfy needs. In order to reduce the government's financial burden, we should expand more financial channels. Therefore, this kind of project financing decision is becoming more and more important. This paper puts forward a method considering policymakers experience combine with objective date. This Information entropy theory model can order according to approach degree in order to select the best scheme, which can provide a kind of subjective and objective for project financing decision combined with decision making method, making the decision more reasonable.

Abstract: With the development of China's power industry, many cities had renovated, expanded electricity power network ,110、220 kV and above the high voltage overhead transmission lines all around the urban areas and residential areas. As the electromagnetic radiation of high-voltage transmission lines inevitability pollute on urban environment, according to the Investigation, monitoring and analysis of high voltage, based on national standard of electromagnetic radiation, this paper proposed the controlling measures and recommendations of electromagnetic radiation. Therefore, the research that the electromagnetic radiation impact on the environmental has a very high value and academic significance.

Abstract: Both firms and government characterized dual and simultaneous behaviors about sustainable buildings energy-saving. This study will formulate 2*2 matrixes to construct four different interactive types about firms and government behaviors such as reaction, leadership, acceptance, and transparadox. In addition, we also analyze that how different types impact sustainable buildings energy-saving. This study not only makes important theoretical contributions on analyzing and exploring firms’ and governmental behavior portfolios for sustainable buildings energy-saving, but also makes significant managerial implication on transferring other three portfolios into transparadox type in order to growing sustainable buildings energy-saving.

Abstract: Series of experimental tests on the forming technique, sintering technique, performance and effectiveness of a new fired brick by mixing municipal sewage sludge and shale are carried out. Test results show that adding sludge properly in the process of manufacture shale fired common brick is feasible. Along with increase of sludge content, the compacting of uniformity of unburned brick decreased and its porosity increased. When shale-sludge mixtures were calcined, the heavy metal solidified, the ignition lost and organic substance volatilized that reduced the unconfined compressive strength (UCS) of the brick and improve its thermal insulation ability. The phase composition and leaching toxicity of sewage sludge-shale baked brick can be up to national standard. Good quality brick can be produced by blending mixture with the optimum moisture content (OMC) 18.0%-20.0%, drying at 105°C and sintering at 960°C. With all being considered in manufacturing brick, the content of sewage sludge shall be controlled within 9.0% that can make UCS of the new brick reach MU10 criterion and it has a superior heat preservation effect to normal brick from clay or shale alone.

Abstract: During a time when environmental issues are one of the biggest problems in the world, the development and growth of developing cities can no longer be discounted. As a typical developing city, the building energy consumption of Lhasa had a large scale increase with the living standard enhancement of people. Through the local measurements, the information as indoor air temperature, the evaluation of the thermal environment and so on was collected. The result shows the existed residential buildings used the direct gain system and the attached solar space system spontaneously. However, the indoor thermal environment still needs to be improved. Considered that Lhasa was classified into central heating area, it will face the problem of huge increasing of the heating energy. The basic models of direct solar gain system were established for studying the affecting rules of passive design elements. The last result gives suggestion for the local residential building design.

Abstract: It has already beocme a common understanding that renewable energy should be fully untilized under the background of the new countryside construction. Due to its merits and special features, superficial thermal energy has attracted great concern from the society. Its utilization is also supported by the governement. In our study, we choose a community in Xixiang county as our resrearch subject. In this community, ground source heat pump technology is adopted to utilize superficial thermal energy.Hopefully, our study will play an active role in exploring new measures for saving energy and reducing emission in the countryside.

Abstract: The paper mainly advances the analyze model on the basis of the relation between the shape coefficient of multi-layer building and building energy saving, the synthetically analysis is finished about effects of the different type models for the results of energy saving through using the TH-BECS2010 software, the analysis includes the facing deriction of the building, shape coefficient , and the parameter of the length, and the width, and the heith of the building etc. for effecting the shape coefficient. The the relative results are subjected that effects about the facing deriction and the shape of multi-layer building for results of energy saving building, it can become the theory basis of energy saving building design.

Abstract: Within the UK bridge engineering sector, fibre-reinforced polymer (FRP) decks have been increasingly used in deck replacement applications. However, study on its environmental performance is limited. This paper examines the environmental credentials of this relatively new decking system by way of a case study comparing its life cycle environmental performance – in carbon terms – with that of conventional concrete decks. In order for the findings to be more general and informative, the bridge is assumed to carry an ‘average’ volume of traffic across the highway network where it is most likely to be present. Based on the results, areas for improvement are identified in order for this decking system to be more environmentally competitive. Uncertainties and limitations of the results are also discussed.

Abstract: Renewable energy use in buildings is a worldwide problem, especially in China; it is under developed and begins very late, so research on BRE suitability for technological theory in buildings is a pressed problem. In this paper, a new understanding for building suitable technology with BEE is put forward and the character of suitability is emphasized with BRE consumption process. In order to improve the energy efficiency suitable technology theory, to produce more suitable environment of human settlements as well, suitability technology theory should be established by regional architecture view. The key to establish firmly building suitable technology theory of energy efficiency is how to exploit the local natural conditions and stick to the requirements for the harmony of human being with environment; this paper sets up the preliminary system frame taking solar energy as an example.
