Abstract

The construction industry as industries that consume a lot of energy and resources, and the weight of the country's total energy consumption, about 30 to 40%. Published by Tsinghua University Building Energy Research Center \In accordance with the relevant statistics, the wall structure of the building envelope heat loss heat transfer heat loss of about 60% to 70%, it is generally by improving the heat transfer coefficient of the building envelope, exterior insulation systems for building walls to increase to reach The purpose of building energy efficiency. The building will also produce a lot of energy at the same time \In the application of exterior insulation system in the building, is not only an important building energy efficiency measures, but also to improve the environment one of the means to achieve sustainable development. Thus, excellent exterior insulation system must not only consider the energy-saving, but also consider its environmental. Exterior insulation system security is also very important, and only to ensure the safety of our lives and property, and other advantages of the thermal insulation system of meaningful. But for developers as well as the construction side, the construction cost seems to choose the use of high-quality thermal insulation system of barriers. In essence, the exterior insulation system of environmental quality in the long-term use of the process of saving the energy value and the resulting environmental benefits and safety benefits, social benefits far beyond its upfront costs. The current evaluation system to stay more on the qualitative analysis, there is no clear and intuitive evaluation results. We only see the results of the evaluation is good, in the end was good, much better, there is no specific data convincing. In view of this situation, this paper presents the external insulation system based on the economic analysis of the cost-effectiveness through the thermal insulation system of energy-saving performance, environmental performance and safety performance results translate into monetary value, then the same cost compared to evaluate. Although not yet found a way to analyze and evaluate the system of the natural environment and the human social and economic systems common metrics, not of true environmental load of the building and building economic, social output unified comparison. The sustainable development of the theory of the research carried out two decades and continue to in-depth, and have accumulated enough data, and also have the scientific means and mechanisms of energy consumption, changes in environmental quality changes and safety risk approximate measured in monetary terms. This paper discusses the thermal insulation system of energy efficiency, the impact on the environment as well as security risks impact into monetary amount, then using the cost-effective method of its evaluation methods and means, this method Jincheng Community Hao Carpenter City The village reconstruction exterior insulation system applications in the residential building # 10 and another wider application of exterior insulation system analysis, comparison and evaluation.
