【摘要】：傳統(tǒng)的建筑設(shè)計產(chǎn)物不單是在施工階段需要消耗數(shù)量巨大的不可再生能源,而且在建成之后同樣需要消耗大量的能源,并且嚴重的污染和破壞環(huán)境。通過建筑熱工性能優(yōu)化可以最大限度的降低能源消耗和提高建筑物整體性能,并且滿足人們對室內(nèi)舒適性的要求。熱工性能優(yōu)化伴隨著初投資以及運行費用的變化,如何客觀地分析優(yōu)化方案的經(jīng)濟性在能源緊缺的今天尤為重要。本文構(gòu)建了基于全生命周期成本控制的BIM協(xié)同設(shè)計平臺,以費用年值法和動態(tài)追加投資回收期作為經(jīng)濟性評價指標(biāo)分析基于所構(gòu)建的BIM協(xié)同設(shè)計平臺完成建筑熱工性能優(yōu)化方案的經(jīng)濟性。本文通過文獻查閱、理論分析、和工程案例研究重點分析下問題： 首先,針對現(xiàn)有的建筑早期設(shè)計過程中熱工設(shè)計優(yōu)化缺乏全面客觀的經(jīng)濟性分析、過分注重初投資等問題,對建筑全生命周期成本、初投資和運行費用三者之間的關(guān)系進行了闡述分析,并研究了建筑熱工性能優(yōu)化方案的經(jīng)濟性分析方法。確定了以全生命周期費用年值和動態(tài)追加投資回收期作為評價指標(biāo)的經(jīng)濟性分析方法。 其次,構(gòu)建基于全生命周期成本控制的BIM協(xié)同設(shè)計平臺,組建以建筑師、暖通工程師、造價師等多專業(yè)協(xié)同工作的建筑熱工優(yōu)化設(shè)計平臺。建筑師通過BIM協(xié)同設(shè)計平臺完成方案的建筑信息模型構(gòu)建,暖通工程師和造價工程師分別對建筑師完成的建筑設(shè)計方案的信息模型進行性能分析和成本分析,再把相關(guān)的分析結(jié)果及建議通過協(xié)同設(shè)計平臺反饋給建筑師來協(xié)助建筑師完成方案的優(yōu)化。 再次,通過呼和浩特市某五層住宅案例基于全生命周期成本的建筑熱工性能優(yōu)化決策流程的分析,從全生生命周期成本最低的角度,確定外墻熱阻提高89.2%、外窗熱阻提高46.5%的熱工性能優(yōu)化方案可以在滿足節(jié)能65%的原方案基礎(chǔ)上再節(jié)能28.72%,追加投資為58.01元/m2,年度節(jié)能收益為14.34元/m2,二氧化碳年排放減少20.66kg/m2,即使考慮到資金的時間價值也只需要不到5年的時間就可以收回追加投資。 最后,本研究在前文提出的基于全生命周期成本控制的BIM協(xié)同設(shè)計平臺中完成了兩個實際工程案例的建筑熱工性能優(yōu)化經(jīng)濟性分析決策方法的應(yīng)用。通過案例分析發(fā)現(xiàn)在滿足當(dāng)前節(jié)能65%的標(biāo)準(北京市居住建筑節(jié)能75%標(biāo)準)的設(shè)計方案中,對方案進行建筑熱工性能優(yōu)化,然后運用全生命周期總成本和追加投資回收期等經(jīng)濟性分析手段確定優(yōu)化方案,可以實現(xiàn)在原節(jié)能設(shè)計標(biāo)準的基礎(chǔ)上再節(jié)能10%-30%,并且追加的初投資可以在很短的時間通過節(jié)能收益來收回。
[Abstract]:Traditional architectural design products not only consume a large amount of non-renewable energy in the construction phase, but also consume a large amount of energy after completion. And serious pollution and damage to the environment. Through building thermal performance optimization can minimize energy consumption and improve the overall performance of the building, The optimization of thermal performance is accompanied by the change of initial investment and operation cost. How to objectively analyze the economy of optimization scheme is particularly important in today's energy shortage. In this paper, a BIM collaborative design platform based on life-cycle cost control is constructed. Based on the annual cost method and the dynamic additional investment payback period as the economic evaluation index, this paper analyzes the economy of the thermal performance optimization scheme of building based on the BIM collaborative design platform. And engineering case studies focus on the following issues:. First of all, in view of the lack of comprehensive and objective economic analysis of thermal design optimization in the early design process of existing buildings, excessive attention is paid to the initial investment and so on. The relationship between initial investment and operation cost is analyzed. The economic analysis method of the optimization scheme of building thermal performance is studied, and the economic analysis method based on the annual value of the whole life cycle cost and the dynamic additional investment payback period is determined. Secondly, the BIM collaborative design platform based on the whole life cycle cost control is constructed, which is composed of architects, HVAC engineers, The building thermal optimization design platform with multi-professional and collaborative work, such as cost engineer, is used by the architect to complete the building information model construction of the project through the BIM collaborative design platform. HVAC engineers and cost engineers analyze the performance and cost of information models of architectural design schemes completed by architects, respectively. Then the related analysis results and suggestions are fed back to the architect through the collaborative design platform to assist the architect to complete the optimization of the project. Thirdly, through the analysis of the decision-making process of building thermal performance optimization based on the whole life cycle cost of a five-story residence in Hohhot City, from the perspective of the lowest cost of the whole life cycle, It is determined that the thermal performance optimization scheme of increasing the thermal resistance of external wall by 89.2and the thermal resistance of outer window by 46.5% can save 28.72 energy on the basis of the original scheme of energy saving 65%, the additional investment is 58.01 yuan / m2, the annual energy saving income is 14.34 yuan / m ~ 2, and the annual carbon dioxide emission is reduced. Less than 20.66 kg / m2, even considering the time value of the capital, takes less than five years to recoup additional investment. Finally, In the BIM collaborative design platform based on the whole life cycle cost control proposed earlier, the application of the economic analysis and decision method of building thermal performance optimization in two practical engineering cases has been completed in this study. The case study shows that the method can be applied to the economic analysis of thermal performance optimization of buildings. In the design scheme of meeting the current energy saving 65% standard (Beijing residential building energy saving 75% standard), The thermal performance of the project is optimized, and the optimization scheme is determined by the economic analysis means such as the total cost of the whole life cycle and the payback period of the additional investment. Energy saving can be realized on the basis of the original energy saving design standard 10-30 and the additional initial investment can be recovered in a very short time through the energy saving income.
