< P> to improve the structure of the need for energy behavior. From the necessity of the original, in order to reduce the heating, ventilation and air conditioning, ing's energy consumption. Energy consumption in building sector constitute the main part of the ( 40% of the annual European final energy use) ( The European commission, 2001). 。 In this the most important part of the energy is consumed, and the demand for space heating cooling, but still relatively small, showed a sharp rise in the trend. In the past three years has been remarkable progress in this respect, as a result of the buildings' bioclimatic design and enhance the application of the principles of thermal protection for decades. The development of the legal framework for typical in Germany, in 1975 as a result, 5 cm to a thermal insulation layer thickness increases to the evolution of the current effective minimum of 20 cm. As a result, the average annual consumption dropped by specific from 1 to 50 300 kWh/m2 1970 kWh/m2 at present. ( 1] 。 In view of the direction of the building and its architectural features, has been highly populated urban environment, also hope and restric building restrictions, heat preservation is still how to establish the important behavior optimization tools [ 2] 。 However, in addition to the purpose of saving energy, for building energy demand behavior optimization has been carried out to focus on the urban environment quality of science and public debate. More energy efficiency of buildings to reduce the consumption of fossil fuels, thereby reducing especially in micro and mesoscale amount of carbon dioxide and sulfur dioxide emissions into the atmosphere. The directive 2002 / for the direction of improving the overall energy efficiency of buildings for energy performance of buildings, 91 / EC change. It shows that the structure of the design and the fact that the primary energy required for operation is low, they will take further measures, to improve the existing energy performance of buildings, should be built in action. It also introduces the building energy performance certificate. 2. In order to minimize the building, the avenue of stars energy consumption because of its shell thermal protection method and grey, electricity was absolutely low conductivity value material, phenolic less than 0. 04 W/mK, has been formulated. The most widely used type of the insulating material is inorganic overseas ¨ ABU Ruth ( Glass and stone wool) And the organic foam ( Extruded polystyrene and expand, and extended to a smaller, pu) And all other materials to pay the remaining 10% of the market ( Mainly wood, wool) 。 More exotic materials, such as transparent and insulation materials on the basis of agricultural raw materials found in the market with limited penetration, mainly because of their high cost. The most widely used in the European market of insulation materials, mineral wool, polystyrene, in stone wool and mineral wool and the main form of extrusion polystyrene. Another point, as in the past ten years is important in insulation materials and building construction and production and operation of environmental and health arising. It has become apparent, considering the fact, insulation materials, until its service life, this is a typical large construction beyond the final from the side effects of their production. 2. Decision-making process can support different types of environmental assessment process. On the point of view of a chain of these tools and methods, focusing on the execution of the decision support some of the basic steps of information all the time. All problems in decision making, first of all need to be defined, standard setting, data and option generation, the final evaluation method, decision feedback, the final choice and implementation. In the process of decision-making problem is a multi-objective problem, namely a lot of tools and methods of combination can be done. Select in decision-making tool is the ultimate goal and the basic standard of data quality requirements. In order to realize the sustainable development and environmental assessment process or products have several kinds of methods and tools to choose from. It depends upon the existing data, the time it takes to provide the supporting technology of elements and the analysis of the depth of the requirements. The decision-making process is an interactive process, from one of these types of analysis used in another way. According to the analysis from the chain of rees's environmental decision support, such as the provision of data. Is the concept of ' ' ' 'to define the concept of how to realize the sustainable development, such as the concept of' ' ' 'life cycle thought, design for the environment, on the other hand tools such as operation method to support the concept of' ' ' '. Analysis tools, to provide a choice of the consequences of programs and tools, the key guide information as a way to decide. All types of tools support technology elements, such as the type, quality evaluation and software. Elements can be separately as a tool of support for the basic concept of ' ' ' '. Figure. 1 describes the contribution to the environment of the tools and concepts of the decision making process. Technical support data. In the modeling analysis tool is a quantitative - Tive or qualitative as to provide more reliable decision information, aimed at the problem of method [ 5] 。 Calculation algorithm is the focus of the analysis tools, need a lot of antibiotics and focus, data. Qualitative analysis tool can be used at the same time, such as qualitative and quantitative data on the list, the problem such as analysis tool may support the decision-making process with or without other analysis tools of synergy. More than a standard is a kind of analysis tools, support for different types of different types of combination of tools and results. In this case, the study and application of tools, in order to realize the cooperation environment evaluation method, feedback, the indicators' two production technology of heat preservation material Settings. More specific, from 'analysis tools'' ' 'and' life cycle analysis' environmental protection input and output analysis' 'implementation of stone wool and extrusion polystyrene ( XPS) The production process. < / P> < P> < / P> < P> < / P>
