The Research Of The Building Skin Assessment In Cold Region

Building as an artificial environment, is to meet human material and spiritual needs of an important part. However, humans have long high consumption, high output, high-pollution development model, and the excessive pursuit of material comforts, so alienated from the modern architecture of man and nature coexist in harmony, to the global ecological environment of the heavy burden. To address the shortage of earth resources and energy, and harmonious coexistence of human and natural problems, mankind must follow the path of sustainable development, construction, strongly advocated to promote building energy efficiency.However, commonly used on our current evaluation of building energy efficiency indicators and methods of most stage building design or construction, building and construction equipment to energy-saving aspects of system still be substantial, the life of building energy consumption type of guidelines have not been more fully reflected, to some extent, this restricted the application of building energy conservation theory and technology's further development. A scientific evaluation methods and systems should be run through the entire life of the building process.Life cycle theory is known as "cradle to grave" theory. Based on full life-cycle perspective, in time, through the building planning and design, building single design, construction, operation and maintenance until the end of life at all stages of demolition, the contents include resources, energy, environment and economy in many ways, the establishment of the building energy efficiency evaluation index system and evaluation according to the level of detail will be divided into three. Then, in view of the structural characteristics of the indicator system, three-stage fuzzy comprehensive evaluation method right evaluation with a view to building energy efficiency evaluation of the qualitative analysis of changes in the quantitative You.Fuzzy comprehensive evaluation method of evaluation, the most important factor is the evaluation system to establish and determine the weight of each factor. This article accordance with the architectural features of the life cycle, the establishment of a multi-level factor system life cycle assessment, and evaluation factors were analyzed in detail so that the evaluation system can be close to the actual object through the evaluation results are more reasonable. In determining the criteria layer target layer of the evaluation factor weight was based upon a qualitative and quantitative analysis of the level of analysis method and analyzing the evaluation factors of evaluation results is the relative important degree, based on a 19 scaling, matrix to determine the weight of the evaluation factors, so that the weight assignment is more scientific, reasonable, and better reflect the impact of various factors on the results of the degree of importance.Finally, Heilongjiang project as an example of a building energy simulation evaluation. The results showed that the use of life cycle theory based on fuzzy comprehensive evaluation method for the whole building life cycle energy assessment is feasible.
