【摘要】:節(jié)能建筑是維持可持續(xù)發(fā)展的重要手段。而對節(jié)能建筑的優(yōu)選也正是達到最大效益的必要途徑。對于節(jié)能建筑的優(yōu)選無可避免地需要節(jié)能建筑的評價指標、指標權(quán)重確定、方案的優(yōu)選方法,即得出節(jié)能建筑優(yōu)選模型。目前國內(nèi)的節(jié)能建筑評價指標主要分為規(guī)定性指標、性能性指標,國外的節(jié)能建筑評價指標主要分為清單列表法、生命周期評價法、基于節(jié)能建筑計算和模擬的評價方法。而對于目前各研究學者所采用的節(jié)能建筑指標的確定方法,主要集中在德爾菲法、層次分析法、熵權(quán)決策法。 本文以某居住建筑為實際項目,對該居住建筑的設計方案進行優(yōu)選研究。本文通過文獻整理、專家訪談,整理得出該居住建筑的初步投資風險清單。并將該居住建筑投資風險初步分為外部風險和內(nèi)部風險兩大類,并且進一步將外部風險分解為政策風險、經(jīng)濟風險、社會風險、自然風險四類,將內(nèi)部風險分解為開發(fā)商自身風險、設計方相關(guān)風險、施工方相關(guān)風險、監(jiān)理方相關(guān)風險、供貨方相關(guān)風險五類。在此基礎(chǔ)之上,通過德爾菲法、主成分分析法進行進一步分析,得出該居住建筑投資風險的關(guān)鍵影響因素,將該居住建筑投資風險指標分解為2個一級風險指標,8個二級風險指標,15個三級風險指標。 在得出該居住建筑的投資風險清單的基礎(chǔ)上,通過文獻整理、專家訪談進一步得出該居住建筑的能耗性指標、經(jīng)濟性指標。并最終綜合風險類指標、能耗性指標、經(jīng)濟性指標,得出該居住建筑的綜合性評價指標。 在得出該居住建筑的綜合性評價指標體系之后,首先運用熵權(quán)法初步確定各指標的初步權(quán)重,其次運用模糊層次分析法(FAHP)對各指標的初步權(quán)重進行修訂。在得出各評價指標的權(quán)重之后,運用理想點法在該居住建筑的16個設計備選方案中篩選出最優(yōu)方案。最終從該居住建筑方案優(yōu)選工作。
[Abstract]:Energy-efficient building is an important means to maintain sustainable development.The optimal selection of energy-efficient buildings is also the necessary way to achieve maximum benefit.The evaluation index of energy-saving building is inevitably needed for the optimal selection of energy-saving building, the index weight is determined and the optimal selection method of the scheme is obtained, that is, the optimal selection model of energy-saving building is obtained.At present, the evaluation index of energy-saving building in China is mainly divided into prescriptive index and performance index. The evaluation index of foreign energy-saving building is mainly divided into list method, life cycle evaluation method, evaluation method based on calculation and simulation of energy-saving building.However, the methods used by scholars to determine the energy saving building index are mainly focused on Delphi method, Analytic hierarchy process (AHP) and entropy weight decision method.In this paper, a residential building as a practical project, the design of the residential building for optimal selection.In this paper, the preliminary investment risk list of the residential building is obtained by literature review and expert interview.The investment risk of residential construction is divided into two categories: external risk and internal risk, and the external risk is further divided into four categories: policy risk, economic risk, social risk and natural risk.The internal risk is divided into five categories: the developer's own risk, the designer's related risk, the construction party's related risk, the supervision's related risk, and the supplier's related risk.On the basis of this, through Delphi method and principal component analysis, the key factors influencing the investment risk of residential construction are obtained.The investment risk index of residential construction is divided into two first-grade risk indicators, eight second-level risk indicators and 15 third-level risk indicators.On the basis of the investment risk list of the residential building, the energy consumption index and the economic index of the residential building are further obtained through literature review and expert interviews.Finally, the comprehensive evaluation index of the residential building is obtained by synthesizing the risk index, the energy consumption index and the economic index.After the comprehensive evaluation index system of the residential building is obtained, the initial weight of each index is determined by entropy weight method, and the initial weight of each index is revised by using fuzzy analytic hierarchy process (FAHP).After the weight of each evaluation index is obtained, the optimal scheme is selected out of the 16 design options of the residential building by using the ideal point method.Finally, from the residential construction scheme to select the best job.
