Benefit Evaluation And Policy Support Of Passive Building

With the fast developing economy and speeding up of urbanization in China, thecity construction, the demand of residents to improve the indoor environment areincreased continually, building energy consumption is also increasing. Therefore, toimprove the traditional construction mode and promote construction of energy savingis imperative and urgent. With the use of passive technology as the key, the passiveenergy-saving building reconstructs the relationship between people, building andclimate. It aimed at transform the traditional construction mode concept and do moreefforts to achieve low energy consumption, low pollution in the whole life cycle, whichis an important way to realize the sustainable development of construction industry.However, the promotion of passive building is still difficult in China: lack of marketrecognition, evaluation system and method is not completed as well as the shortage ofincentive policy and so on. Thus, it is significance to study the basis of passiveconstruction.This paper begin with the background of energy saving building, first of all, by alarge number of literature review and on the basis of current passive building of Chinaand foreign country, comparing the concept of sustainable construction and deepen theunderstanding of passive construction. According to the economic externality theory,energy-environment-economic integration theory, sustainable development theory andsystem evaluation theory, the paper analyze the comprehensive benefit of passivebuilding–economic benefit, social benefit, ecological benefit and technical benefit.And then put forward the basic principle of evaluation system and constructingevaluation index system of comprehensive benefits and use AHP to determine the indicators at each level. In order to verify the efficiency and effectiveness of theevaluation index system of the actual maneuverability, this paper carry on theempirical analysis of S hotel in Xi’an, using comprehensive Fuzzy SyntheticEvaluation method to analyze its comprehensive benefit condition and then determinethe value of social practice. Finally, analyzing the obstacles of development of passivebuilding and put forward the policy.The innovation of this paper is to establish the passive energy saving building’seconomic benefit, social benefit, ecological benefit and technical benefit by researchthe results from domestic and foreign countries. By carry out the empirical analysis,this paper could identify the scientific nature and operability of the case study, and alsocould enrich the content of theoretical research thus promoting the development ofpassive construction.
