Abstract: Sea water heat pump, which is an emerging ocean energy utilization technology with advantages of energy saving and environmental friendly, has great development potential in costal and islands areas. This article analyze the global development status, technologies and application prospects of sea water heat pump to give reference for its developments in costal and islands areas.

Abstract: the content focuses on the principle that electrical energy saving design should follow, which discusses the technical measures of architecture electrical energy saving and its reasonable applications in engineering design by various aspects and terms such as transformer selection, supply and distribution system and line design, system power factor improvement, lighting energy saving, motor energy saving, power saving type LV electronics selection, etc.

Abstract: In China, it covers a sea area of about 4.73 million square kilometers, with a mainland coastline of about 18 thousand kilometers. Seawater is ideal as a heat source or sink of heat pump for heating or cooling and seawater source heat pump (SWHP) technology is a promising way to utilize ocean thermal energy. At present, SWHP has been well used in China. The article presents the application of SWHP in some cities, such as Dalian, Tianjin and Qingdao etc. Summary of these successful practical experiences of SWHP aims at informing the design for other similar projects.

Abstract: According to transverse load test on two half-scale energy-saving wall panels with different space. It is analyzed these panels with failure processes, failure modes, ultimate bearing capacity, load-deflection curves, concrete load-strain curves and steel load-strain curves. The results show that failure modes, flexural stiffness and ultimate strength of panels are affected by ratio of steel.

Abstract: Light steel structure residence is an optimum selection for the realization of building energy-saving and meeting of green building evaluation standards. Two kinds of system of light steel structure are analyzed and construction method for lightweight combination wall and infilled outer walls of low-rise light steel are summed up. Analysis on exterior wall conformation in low-rise light steel structure is put forward. Results indicate that special construct of light steel structure is equivalent to set closed air space, and thermal performance of infilled external wall of light steel structure is superior to that of traditional structure. And thermal performance of using aerated concrete wall panels as filled outer wall of light steel structure is better than that of aerated concrete blocks and thermal stability of filled external wall of light steel structure is better than lightweight combination external wall. The conclusions provide a theoretical foundation for building energy-saving in light steel structure residence and optimal design of residential environment.

Abstract: The energy saving renovation of existing buildings on campus sunshade design are analyzed from the aspects of shading on campus.in view of existing residential buildings in the reality, puts forward the corresponding the possibility of shading design method, and the study of different building parts for sunshade measures, so as to achieve the effect of shading design and value.

Abstract: All of public buildings, commercial building is a special type of energy consumption larger, especially the energy consumption of air conditioning. This paper illustrates entrance space of commercial building in cold region of China as the research project, studying its energy-saving design. Aiming at the problems existing in the present designs, this paper puts forward some targeted solution measures: adopt reasonable entry form, increase thermal damping space, expand the entrance area and make full use of solar energy. These measures can reduce the heat loss of the entrance space, improve thermal comfortableness, and achieve the goal of energy saving.

Abstract: Energy-saving work has made great achievements in our country, the index of heat loss of building of per building area in new residential buildings fell sharply, but total energy consumption and the proportion of it in social total energy consumption is rising. A large number of coal, oil, gas and other fossil energy use, caused the climate warming and so on the adverse effects on the human survival environment, these phenomena, warns us to further strengthen the importance of building energy-saving work.

Abstract: This template explains about testing the thermodynamic defect of building’s energy efficiency through the thermal infrared imager intuitively and without loss in a large area. And it uses examples to analyze the forming reasons of the thermodynamic defect,to reduce the loss of resource and energy and achieve a sustainable development goal.

Abstract: Wind power industry development is one focus of clean energy. From the perspective of industrial agglomeration effect, this paper studied the development of Chinese wind power industry chain. The location quotient (LQ) was used to research the wind power industry agglomeration in North China, Northeast China, Northwest China and Jiangsu coastal areas, and it proves that wind power industry agglomeration is existented in the four regions. The concentration ratio (CR) was used to research the market concertration in these regions, and it proves that the different industial agglomeration degree may lead to different characteristics of wind power industry. The result is that we should connect wind power industry chains in China to promote national industrial development, like the power transmission from west to east.
