Abstract: Analyzed the status of Liaoning Province Existing Building Energy Saving, and elaborate the role of economic incentives in the Existing Building Energy Saving. Proposed the establish principles and design ideas of Existing Building Energy Saving economic incentive policies in Liao Ning Province on the basis of learning from the developed countries economic incentives successful experience. Developed economic incentives on taxation, loans, and subsidies and so on.

Abstract: Summarized all kinds of existing public buildings energy consumption status and characteristics in Shenyang, analysis the problems and current situation of the existing public buildings energy-saving in Shenyang city during the period of "eleven five" ,put forward the countermeasures and suggestions to speed up the development of the energy-saving of existing public buildings in Shenyang from the aspects of energy-saving evaluation and examination, energy conservation supervision, management mechanism, energy saving system etc.

Abstract: According to the mass and energy conservation principle of simulation program TOUGH2 used for non-isothermal multi-phase fluid and heat flow in porous and fractured media, the heat transport mathematical model of low-temperature shallow geothermal system is set up in homogeneous porous medium. The fundamental scientific issues on heat transfer characteristics and distribution of transient temperature field of heat exchange wells in summer is discussed in this paper. In addition, the significance and correlation between the changes of hydrogeology parameters and temperature field of the soil is analyzed. So as to the practical application of geothermal energy development can be guided by the achievements of the research.

Abstract: This article studies the possibilities of using lightweight porous concrete, which is intended for insulation of thermally intensive equipment and the effect of its use under specific circumstances on the change of the building envelope thermal resistance. The material should combine benefits of the porous and foamed concretes produced so far (low bulk density, high thermal resistance, low production costs) with higher thermal resistance. The benefit of the new material is its ability to also perform at higher temperatures due to the selection of suitable raw materials.

Abstract: in the context of China accelerates the new rural construction and promotes residential energy-saving, through a combination of Gansu climate, resources and rural house features, analyzed the material selection, forms and practices of rural house envelope, found the fundamental cause of leading the energy consumption and poor insulation in local rural house, and made some concrete improvements. Meanwhile, studied the application of passive solar houses, solar water heaters, as well as "four in one" type of biogas energy utilization system model in a local rural house, to improve energy efficiency and provide a reference to the new rural development.

Abstract: The construction of envelope insulation building is an important part of building energy-saving engineering. For the strict control of the external structure, is to promote the most effective mean of building energy efficiency. EPS thermal insulation system and exterior window insulation system as external structure of the master project, the construction should be integrated control system strengthening.

Abstract: The improving the economic content of ecological and energy-saving residence design is stressed, under the conditions of meeting the applicable and safety, the cost is reduced, society resources are fully used, and on this basis the safeguard measures to realize the ecological energy-saving residential design are put forward. At the same time, the technical and economic analysis should be accompanied by the whole process of architectural design is emphasized, from the design preparation, and extending beyond the evaluation stage for the construction in use .

Abstract: Taking a residential project as an example, the design of technical and economic evaluation of ecological residential energy conservation is analyzed, in order to realize the healthy development of energy-saving residential building ecological.

Abstract: Using the energy consumption simulation software to research the HVAC in fall air conditioning mode, different building orientation and window-wall ratio of the office building energy consumption. The study found that the heating energy consumption, air-conditioning energy consumption and total energy consumption is gradually increased with the increase of the window-wall ratio under the same orientation. The result provides some reference for public buildings in setting of building orientation and window-wall ratio.

Abstract: The urban heat island phenomenon is one of the important problems faced by the metropolitan environment in hot-summer and cold-winter areas. In order to conduct truthful and in-depth analysis on this phenomenon, this study covers temperature data acquisition and a series of data collation and analysis conducted with the mobile testing method, more actually reflects the heat island spatial-temporal changes from the central area of Wuhan in Winter to the urban fringe, analyzes the urban morphology, urban underlying surface characteristics, and impacts of human factors and microclimate, and explores the feasible quantification basis for urban design and planning.
