【摘要】：建筑节能是我国可持续发展战略以及能源战略的重要策略之一。积极贯彻实施建筑节能相关法规措施有利于我国社会和经济的可持续性发展。我国的严寒寒冷地区居住建筑已全面实行节能65%的标准，，夏热冬冷地区部分城市已经颁布以节能65%为目标的节能设计标准。夏热冬暖地区虽尚未颁布相应的节能标准，但部分居住建筑节能率也已达到65%。目前居住建筑仍是广州市房地产开发项目的重点，全面提高广州市居住建筑的节能率至65%可产生重大的节能效益。结合广州市建筑及气候特点本文从主要从提高围护结构的热工性能以及提高空调设备的能效比两个方面研究居住建筑节能65%技术体系及实现节能65%的节能技术应用。本文的主要内容如下：（1）对广州市居住建筑信息进行了调研，抽取了2008年—2011年间广州市居住建筑的节能备案资料201份作为有效调研样本，统计分析得出广州市居住建筑特征，得出建筑节能率的高低为节能技术集成的结果，同时反映出商业决策是决定建筑节能率大小的一个重要因素，并根据调研统计数据，采用多元回归的方法得到了建筑节能率与建筑的围护结构热工参数的关系式，外窗综合遮阳系数、外墙传热系数、窗墙面积比对建筑节能率的影响显著。（2）采用正交试验的方法分析得出了多因素共同作用下建筑能耗影响因素对建筑能耗的影响大小依次为：外窗综合遮阳系数＞墙面积比＞外墙传热系数＞屋顶传热系数。通过能耗模拟量化研究建筑能耗各影响因素的节能率大小，得出外窗综合遮阳系数对建筑的节能率最大，进而研究还发现在广州地区，按照当地的人们生活习惯，外窗综合遮阳系数对建筑能耗的影响要比全天空调开启模式下计算结果大，窗墙面积比对建筑能耗的影响要比全天空调开启模式下计算结果小。（3）根据调研数据以及影响因素对建筑能耗的影响大小，通过大量模拟计算得出满足节能65%的技术指标，该指标借鉴现行节能设计标准，并考虑了外窗传热系数对建筑能耗的影响，对外墙和屋顶的传热系数进行了适当的提高，主要对建筑的综合遮阳系数进行了调整。本文还研究了实现节能65%的相关的节能技术，并采用实际案例进行了验证分析，从另一方面验证了节能65%规定性指标的科学性及可行性，为制定广州市居住建筑节能65%设计标准提供了一定的技术支持。
[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.
