【摘要】：面對人均可采能源儲(chǔ)量不豐,建筑用能巨大,大氣污染嚴(yán)重的嚴(yán)峻形勢下,建筑節(jié)能的迫切性是毋庸置疑的。本文首先通過文獻(xiàn)閱讀對于國內(nèi)外建筑節(jié)能的發(fā)展情況進(jìn)行了比較與分析,得到以下三點(diǎn)發(fā)現(xiàn):一是對于建筑節(jié)能領(lǐng)域的研究主要集中在節(jié)能保溫材料的開發(fā)與建筑節(jié)能技術(shù)的研究;二是外墻外保溫系統(tǒng)是目前建筑圍護(hù)結(jié)構(gòu)主要采用的模式,是影響建筑節(jié)能效果的重要因素;三是對于目前現(xiàn)行的各類建筑節(jié)能系統(tǒng),尤其是外墻外保溫系統(tǒng)的保溫隔熱效果的綜合評價(jià)的研究是很少的。因此,希望可以通過本文的研究與分析建立一套節(jié)能外墻外保溫系統(tǒng)的評價(jià)體系,為之后的外墻外保溫系統(tǒng)類型、材料的選擇提供一個(gè)優(yōu)選的機(jī)制,達(dá)到既能節(jié)約成本又能最大程度節(jié)能保溫的效果。本文研究的范圍為行政區(qū)劃的蘇南地區(qū),包括南京、鎮(zhèn)江、蘇州、無錫、常州五市。該地區(qū)是典型的長江流域氣候,屬于夏熱冬冷地區(qū)。該地區(qū)建筑節(jié)能有兩大要求:一,改善夏季高溫時(shí)建筑熱環(huán)境;二,提高冬季低溫時(shí)隔熱保溫效率。根據(jù)《建筑節(jié)能工程施工質(zhì)量驗(yàn)收規(guī)范》(GB50411-2007)在蘇南地區(qū),節(jié)能分部工程驗(yàn)收前都對圍護(hù)結(jié)構(gòu)進(jìn)行現(xiàn)場熱工性能檢測,根據(jù)實(shí)測所得傳熱系數(shù)值來判定外墻節(jié)能工程質(zhì)量和節(jié)能效果做出評判,因此,本文在熱工性能檢測報(bào)告的基礎(chǔ)上建立評價(jià)體系。通過參與由江蘇省建筑節(jié)能技術(shù)中心、江蘇省住建廳科技發(fā)展中心、江蘇省建設(shè)工程質(zhì)量監(jiān)督總站對我省主要外墻外保溫系統(tǒng)(材料)及主要外墻外保溫工程質(zhì)量的調(diào)查活動(dòng),通過適宜性分析確定了蘇南地區(qū)的五類主要外墻外保溫系統(tǒng)。根據(jù)調(diào)查問卷的結(jié)果,基于SPSS軟件進(jìn)行指標(biāo)篩選出技術(shù)指標(biāo)、經(jīng)濟(jì)指標(biāo)、施工指標(biāo)、環(huán)境指標(biāo)4個(gè)一級指標(biāo)和16個(gè)二級指標(biāo)。針對這五大類外墻外保溫系統(tǒng)的50組熱工性能檢測報(bào)告進(jìn)行數(shù)據(jù)歸一化處理,利用支持向量機(jī)理論建立評價(jià)模型,使用Matlab2013編寫程序運(yùn)行實(shí)例驗(yàn)證評價(jià)模型的可行性和可靠性。本文最終完成了一套針對蘇南地區(qū)五大類主要外墻外保溫系統(tǒng)的評價(jià)體系,得到了高精度的建筑節(jié)能效果評價(jià)模型。雖然該評價(jià)體系具有一定的局限性,但是希望能過為日后建筑節(jié)能設(shè)計(jì)、選材、施工等方面提供技術(shù)參考,為貫徹國家可持續(xù)發(fā)展戰(zhàn)略貢獻(xiàn)一份綿薄之力。
[Abstract]:Faced with the severe situation that the per capita recoverable energy reserves are not abundant, the building energy consumption is huge, and the air pollution is serious, the urgency of building energy saving is beyond doubt. First of all, this paper compares and analyzes the development of building energy conservation at home and abroad through literature reading. The main findings are as follows: first, the research in the field of building energy conservation is mainly focused on the development of energy-saving and thermal insulation materials and the research of building energy conservation technology; second, the external insulation system of external wall is the main mode used in building envelope structure at present. It is an important factor that affects the effect of building energy conservation. Thirdly, there is little research on the comprehensive evaluation of the thermal insulation effect of all kinds of building energy saving systems, especially the external wall insulation system. Therefore, it is hoped that through the research and analysis of this paper, a set of evaluation system of energy saving external wall thermal insulation system can be established, which can provide an optimal selection mechanism for the type of external wall thermal insulation system and the selection of materials. It can not only save cost but also save energy and heat preservation to the greatest extent. The scope of this study is the administrative division of southern Jiangsu, including Nanjing, Zhenjiang, Suzhou, Wuxi, Changzhou five cities. This area is a typical Yangtze River basin climate, belong to hot summer and cold winter area. There are two requirements for building energy conservation in this area: one is to improve the thermal environment of buildings during high temperature in summer, the other is to improve the efficiency of heat insulation in winter. According to the Code for acceptance of Construction quality of Building Energy-saving Engineering (GB50411-2007) in southern Jiangsu, the thermal performance of envelop structure is tested before acceptance of energy saving partial project. According to the measured heat transfer coefficient value to judge the external wall energy saving engineering quality and the energy saving effect to make the judgment, therefore, this article establishes the appraisal system based on the thermal performance inspection report. By participating in the investigation activities of the Jiangsu Provincial Building Energy Saving Technology Center, the Jiangsu Provincial living and Construction Office Science and Technology Development Center, the Jiangsu Provincial Construction Project quality Supervision General Station, the main external wall thermal insulation system (materials) and the main external wall external insulation project quality of our province, Through suitability analysis, five kinds of main exterior wall external insulation systems in southern Jiangsu are determined. According to the results of the questionnaire, the technical index, economic index, construction index, environmental index, four first class index and 16 second grade index were selected based on SPSS software. In view of the 50 groups of thermal performance test reports of these five types of exterior wall thermal insulation systems, the data are normalized, the evaluation model is established by using support vector machine theory, and the feasibility and reliability of the evaluation model are verified by a program running example written in Matlab 2013. In this paper, a set of evaluation system for five main types of exterior wall thermal insulation system in southern Jiangsu is completed, and a high-precision evaluation model of building energy saving effect is obtained. Although the evaluation system has some limitations, it is hoped that it can provide technical reference for building energy-saving design, material selection and construction in the future, and contribute a modest contribution to the implementation of the national sustainable development strategy.
