The Research On Risk Management Of Energy-saving Building In The Construction Process

In China’s energy consumption structure, the building energy consumption accounted formore than30%of the total energy consumption, therefore, accelerate the building energyefficiency work is one of the effective means to resolve the contradiction between supply anddemand of energy, energy-efficient buildings as an important way of building energyconservation, is the basis to carry out the building energy conservation. For now, our countryhas been enforced building energy efficiency standard of65%in newly renovated andexpanded buildings, however, at this stage there are many risk factors in the construction ofenergy efficient buildings, and the research on energy efficient building construction risks isbasically a blank, if these risks in the process of construction are not controlled in time, thereis no doubt that it will affect the application of energy-saving building.Combining the characteristics of energy-efficient buildings, apply the basic principle ofproject risk management, in the foundation of in-depth analysis of the implementation issuesfor the promotion of the energy-efficient building and the status of risk management，thispaper conducts the research on the energy-saving building’s infrastructure risks from severalaspects：First, by analyzing the development status and existing problems of the energy-savingbuilding risk management at home and abroad, in the light of the characteristics of energysaving buildings this paper raised the risk characteristics of energy-efficient buildings, andunder the unified project management objectives, builded the risk identification dimensionalmodel of energy-saving building from two angles of the whole process of project constructionand the parties.Secondly, through referring data about risk management at home and abroad, and adaptcombination of empiricalanalysis、practical research and expert survey, this article identified the risks inthe process of construction of energy-saving building, then put these factorsaccording to the hierarchical relationships form a class hierarchy, established a constructionrisk index system of the Energy-saving building.Moreover, it introduced the engineering project risk assessment methods, based on theanalysis of the advantages and disadvantages of various evaluation methods and the scope ofapplication, this paper put forward the risk evaluation model of energy saving building basedon fuzzy analytic hierarchy process (FAHP) model. Through on-the-spot investigation andresearch about the risks of certain energy-efficient buildings in Xi’an, by using the evaluationmodel calculate the risk level of the project, verified the applicability of the evaluation modelin energy-efficient buildings risk assessment.Finally, to reduce the risk loss of energy efficient buildings, raise the level ofenergy-saving building risk management, this article discussed how to control and preventionthe constructure risk combined with practical engineering, proposed strategies for reference inview of the specific risk factors, and on this basis established a construction risk managementsystem of energy-saving building based on the workflow.
