【摘要】：2015年我國公共建筑能耗占建筑總能耗的33%左右,其中高層辦公建筑能耗約占公共建筑能耗的30%,因此降低高層辦公建筑能耗可有效降低我國城鎮(zhèn)建筑能耗。本文以長沙市某新建高層辦公建筑為對象,分析了各項建筑節(jié)能技術(shù)對該建筑能耗的影響水平,并提出了適合于該建筑的建筑節(jié)能技術(shù)優(yōu)化組合方案。根據(jù)該高層辦公建筑的基本信息,建立物理模型,以1980年代公共建筑的圍護結(jié)構(gòu)做法作為參照建筑,進行實際建筑和參照建筑的能耗分析,結(jié)果顯示實際建筑比參照建筑節(jié)能60.53%。在此基礎(chǔ)上,將該辦公建筑能耗分類為照明系統(tǒng)能耗、圍護結(jié)構(gòu)能耗和空調(diào)系統(tǒng)能耗,分析現(xiàn)有節(jié)能技術(shù)不同參數(shù)值對以上三種能耗的影響,并得出了降低該建筑能耗的節(jié)能技術(shù)組合:照明系統(tǒng)采用低照明功率密度值和優(yōu)化照明控制技術(shù),圍護結(jié)構(gòu)采用外墻保溫技術(shù)、屋頂保溫技術(shù)和節(jié)能保溫外窗,空調(diào)系統(tǒng)采用高COP直燃機組、變頻水泵系統(tǒng)、高效率水泵、雙速冷卻塔風(fēng)機、新風(fēng)熱回收等技術(shù)。分析了以上各因素對建筑節(jié)能率的影響,并選出對建筑能耗影響較大的8種節(jié)能技術(shù)為試驗因素:水泵效率、外窗遮陽系數(shù)、變頻水泵系統(tǒng)、照明功率密度、照明控制方式、直燃機能效比、外窗傳熱系數(shù)、外墻保溫等,利用均勻設(shè)計法和多元線性回歸分析方法,對該高層辦公建筑進行整體性的能耗分析,研究各項節(jié)能技術(shù)對建筑能耗的影響水平,結(jié)果顯示各項技術(shù)對該建筑能耗影響水平的顯著性大小順序為:照明功率密度照明控制方式水泵類型外窗遮陽系數(shù)水泵效率直燃機能效比(外窗傳熱系數(shù)和外墻保溫對建筑能耗影響不顯著);對該建筑空調(diào)能耗影響水平的顯著性大小順序為:水泵類型外窗遮陽系數(shù)水泵效率直燃機能效比照明功率密度外窗傳熱系數(shù)外墻保溫(照明控制方式對空調(diào)能耗影響不顯著)。在此基礎(chǔ)上得到了適合該建筑的建筑節(jié)能優(yōu)化組合方案,計算結(jié)果顯示該方案的建筑節(jié)能率為68.5%,比實際建筑能耗降低13.78%。
[Abstract]:In 2015, the energy consumption of public buildings in China accounted for about 33% of the total energy consumption of buildings, and the energy consumption of high-rise office buildings accounted for about 30% of the energy consumption of public buildings. Taking a newly built high-rise office building in Changsha City as an object, this paper analyzes the influence level of various energy-saving technologies on the energy consumption of the building, and puts forward an optimized combination scheme of building energy-saving technology suitable for the building. Based on the basic information of the high-rise office building, the physical model is established and the energy consumption analysis of the actual building and the reference building is carried out based on the enclosing structure practice of the public buildings in the 1980s as a reference building. The results show that the actual building is more energy efficient than the reference building 60.53%. On this basis, the energy consumption of the office building is classified as the energy consumption of the lighting system, the energy consumption of the enclosure structure and the energy consumption of the air-conditioning system, and the influence of the different parameters of the existing energy-saving technologies on the above three energy consumption is analyzed. The energy saving technology combination of reducing the energy consumption of the building is obtained: low lighting power density value and optimized lighting control technology are adopted in lighting system, exterior wall insulation technology, roof insulation technology and energy saving heat preservation window are adopted for exterior wall insulation structure, roof insulation technology and energy saving heat preservation window, respectively. The air conditioning system adopts high COP direct combustion unit, variable frequency pump system, high efficiency pump, double speed cooling tower fan, fresh air heat recovery and so on. This paper analyzes the influence of the above factors on building energy saving rate, and selects 8 energy saving technologies which have great influence on building energy consumption as experimental factors: pump efficiency, sunshade coefficient of outer window, variable frequency pump system, lighting power density, lighting control mode, etc. The energy efficiency ratio of direct combustion turbine, heat transfer coefficient of outer window and exterior wall heat preservation, etc., are analyzed by uniform design method and multiple linear regression analysis method, and the influence level of energy saving technology on building energy consumption is studied, and the energy consumption of the high-rise office building is analyzed by means of uniform design method and multiple linear regression analysis method. The results show that the significant order of the influence of various technologies on the energy consumption of the building is as follows: lighting power density lighting control mode water pump window shade coefficient pump efficiency direct gas turbine energy efficiency ratio (external window heat transfer coefficient and exterior wall) The influence of heat preservation on building energy consumption is not significant); The significant order of the influence level of air conditioning energy consumption in this building is as follows: water pump type outer window sunshade coefficient pump efficiency direct gas turbine energy efficiency ratio lighting power density exterior window heat transfer coefficient external wall insulation (lighting control mode has no significant effect on air conditioning energy consumption). On this basis, the optimum combination scheme for building energy efficiency is obtained. The calculation results show that the energy saving rate of the building is 68.5%, which is 13.78% lower than the actual building energy consumption.
