Technical And Economic Analysis Of Insulating Layer In Building Maintenance

China is the world's second largest energy consuming country, which accounted for 30% of the total energy of the building with the use of energy in the nation first in all kinds of energy, so energy-efficient building energy efficiency as an important part of the country. In general civil construction, the roof about the whole building heat loss around 20% of heat loss, thus building the importance of rational use of thermal insulation materials. On the one hand, the use of thermal insulation materials can improve the insulation effect, reduce the heating, air-conditioning energy consumption, efficient energy conservation; on the other hand, choosing the right insulation thickness can save building materials, reduce construction costs, effectively increase economic efficiency. However, blindly increasing the thickness of insulation layer and the use of the best insulation material is neither economic nor necessary, it is necessary to meet the comfort, under the premise of selecting the most appropriate thickness.Building energy-saving insulation layer to maintain the structure into a wall or failure is often the reason because we have to maintain the structure of the building insulation lack of comprehensive knowledge. At the same time, because we recognize that too much emphasis on the utilitarian nature of a unilateral make us the choice of extreme thermal insulation material. China is still lack of a unified set of pairs of building insulation to maintain the structure of the system to recognize this article as much as possible to address these issues from construction to maintain the structure of the various levels, such as technical analysis of insulation materials, building maintenance of the structure of technical analysis, economic analysis of insulation materials, etc. to conduct a comprehensive study of its understanding.Specifically, the contents of this article include:1 On the Building Maintenance properties of structural materials. An analysis of its comprehensive performance indicators, including environmental indicators, thermal conductivity coefficient, bulk density, maximum operating temperature, moisture content, flexural strength, compressive strength and so on. According to the actual situation, determine the specific basis for selection, select a suitable insulation material.2 On the technical analysis, the first is to maintain the structure of the building described in the definition, and then analyze the insulating layer of concrete existence of two parts, one is the exterior walls, a roof construction. Both were described insulating layer of construction problems, as well as their own could be the solution.3 Pairs of thermal insulation materials, economic analysis. As in the study, we can use different methods to conduct economic analysis on the insulation layer, whether these different approaches influence the final outcome we do not know, for example, this article in full life-cycle analysis methods, the smallest annual average cost of heating method, Lagrange multiplier method and so on.This paper attempts to find a way through the study of the above to select the most suitable building to maintain the structure.
