【摘要】：建筑節(jié)能是我國可持續(xù)發(fā)展戰(zhàn)略以及能源戰(zhàn)略的重要策略之一。積極貫徹實施建筑節(jié)能相關(guān)法規(guī)措施有利于我國社會和經(jīng)濟的可持續(xù)性發(fā)展。我國的嚴寒寒冷地區(qū)居住建筑已全面實行節(jié)能65%的標準，，夏熱冬冷地區(qū)部分城市已經(jīng)頒布以節(jié)能65%為目標的節(jié)能設(shè)計標準。夏熱冬暖地區(qū)雖尚未頒布相應的節(jié)能標準，但部分居住建筑節(jié)能率也已達到65%。目前居住建筑仍是廣州市房地產(chǎn)開發(fā)項目的重點，全面提高廣州市居住建筑的節(jié)能率至65%可產(chǎn)生重大的節(jié)能效益。結(jié)合廣州市建筑及氣候特點本文從主要從提高圍護結(jié)構(gòu)的熱工性能以及提高空調(diào)設(shè)備的能效比兩個方面研究居住建筑節(jié)能65%技術(shù)體系及實現(xiàn)節(jié)能65%的節(jié)能技術(shù)應用。本文的主要內(nèi)容如下： （1）對廣州市居住建筑信息進行了調(diào)研，抽取了2008年—2011年間廣州市居住建筑的節(jié)能備案資料201份作為有效調(diào)研樣本，統(tǒng)計分析得出廣州市居住建筑特征，得出建筑節(jié)能率的高低為節(jié)能技術(shù)集成的結(jié)果，同時反映出商業(yè)決策是決定建筑節(jié)能率大小的一個重要因素，并根據(jù)調(diào)研統(tǒng)計數(shù)據(jù)，采用多元回歸的方法得到了建筑節(jié)能率與建筑的圍護結(jié)構(gòu)熱工參數(shù)的關(guān)系式，外窗綜合遮陽系數(shù)、外墻傳熱系數(shù)、窗墻面積比對建筑節(jié)能率的影響顯著。 （2）采用正交試驗的方法分析得出了多因素共同作用下建筑能耗影響因素對建筑能耗的影響大小依次為：外窗綜合遮陽系數(shù)＞墻面積比＞外墻傳熱系數(shù)＞屋頂傳熱系數(shù)。通過能耗模擬量化研究建筑能耗各影響因素的節(jié)能率大小，得出外窗綜合遮陽系數(shù)對建筑的節(jié)能率最大，進而研究還發(fā)現(xiàn)在廣州地區(qū)，按照當?shù)氐娜藗兩盍晳T，外窗綜合遮陽系數(shù)對建筑能耗的影響要比全天空調(diào)開啟模式下計算結(jié)果大，窗墻面積比對建筑能耗的影響要比全天空調(diào)開啟模式下計算結(jié)果小。 （3）根據(jù)調(diào)研數(shù)據(jù)以及影響因素對建筑能耗的影響大小，通過大量模擬計算得出滿足節(jié)能65%的技術(shù)指標，該指標借鑒現(xiàn)行節(jié)能設(shè)計標準，并考慮了外窗傳熱系數(shù)對建筑能耗的影響，對外墻和屋頂?shù)膫鳠嵯禂?shù)進行了適當?shù)奶岣�，主要對建筑的綜合遮陽系數(shù)進行了調(diào)整。本文還研究了實現(xiàn)節(jié)能65%的相關(guān)的節(jié)能技術(shù)，并采用實際案例進行了驗證分析，從另一方面驗證了節(jié)能65%規(guī)定性指標的科學性及可行性，為制定廣州市居住建筑節(jié)能65%設(shè)計標準提供了一定的技術(shù)支持。
[Abstract]:Building energy saving is one of the important strategies of sustainable development strategy and energy strategy of our country. It is beneficial to the sustainable development of our society and economy to carry out the relevant laws and regulations of building energy saving actively. Residential buildings in the district have fully implemented the standard of energy saving 65%. Some cities in hot summer and cold winter area have issued energy-saving design standards aiming at energy saving 65%. Although the corresponding energy saving standards have not been promulgated in hot summer and warm winter areas. However, the energy saving rate of some residential buildings has also reached 65. At present, residential building is still the focus of Guangzhou real estate development project. Comprehensive improvement of energy saving rate of residential buildings in Guangzhou to 65% can bring about significant energy-saving benefits. Based on the characteristics of buildings and climate in Guangzhou, this paper mainly discusses how to improve the thermal performance of enclosure structure and improve the energy efficiency of air conditioning equipment. Compared with two aspects, this paper studies the energy saving 65% technology system of residential buildings and the energy saving technology application of realizing energy saving 65%. The main contents of this paper are as follows:. 1) based on the investigation of residential building information in Guangzhou, 201 energy saving records of residential buildings in Guangzhou from 2008 to 2011 were selected as effective survey samples. Statistical analysis of the characteristics of residential buildings in Guangzhou, it is concluded that the building energy saving rate is the result of energy saving technology integration, and reflects that commercial decision-making is an important factor to determine the building energy saving rate. According to the investigation and statistical data, the relationship between the building energy saving rate and the thermal parameters of the building envelope structure, the comprehensive sunshade coefficient of the outer window and the heat transfer coefficient of the exterior wall are obtained by using the method of multiple regression. The effect of the area ratio of window to wall on building energy saving rate is significant. 2). By using the method of orthogonal test, it is concluded that the influence of the factors of building energy consumption on building energy consumption under the action of multiple factors is as follows:. Comprehensive sunshade coefficient > wall area ratio > heat transfer coefficient of exterior wall > heat transfer coefficient of roof. The result shows that the comprehensive sunshade coefficient of the outer window can save the most energy of the building, and the study also found that in Guangzhou area, according to the local people's living habits. The influence of the comprehensive shading coefficient of outer window on building energy consumption is greater than that under all-day air conditioning open mode, and the effect of window area ratio on building energy consumption is less than that under all-day air conditioning open mode. According to the investigation data and the influence of influencing factors on building energy consumption, the technical index of energy saving 65% is obtained through a large number of simulation calculations, which draws lessons from the current energy saving design standards. The influence of outer window heat transfer coefficient on building energy consumption is considered, and the heat transfer coefficient of exterior wall and roof is improved appropriately. This paper mainly adjusts the comprehensive shading coefficient of the building. This paper also studies the energy saving technology related to the realization of energy saving 65%, and uses a practical case to verify the analysis. On the other hand, it verifies the scientificity and feasibility of the specification index of energy saving 65%, and provides certain technical support for formulating the design standard of energy saving 65% of residential buildings in Guangzhou.
