【摘要】：近年來高校校園能耗水平升高，校園能耗主要來源于校園內大量存在的對節(jié)能設計考慮不足的既有建筑，對校園既有建筑進行節(jié)能改造，降低建筑能耗，是解決高校校園能耗問題的關鍵。 本文將夏熱冬暖地區(qū)高校既有建筑與建筑節(jié)能技術結合，研究分析當前夏熱冬暖地區(qū)高校既有建筑能耗特征及適宜的節(jié)能改造技術。 以廣州大學為例，分析夏熱冬暖地區(qū)高校既有建筑的用能水平、能耗變化規(guī)律及建筑能耗強度，確定教學建筑、學生宿舍及圖書館的能耗占校園能耗比重較大且能耗強度較高，是校園建筑節(jié)能改造的重點。 以廣州大學教學建筑作為研究對象，采用數值模擬方法，研究建筑圍護結構熱工性能對教學建筑能耗的影響。通過15個節(jié)能改造方案對比分析發(fā)現，外窗遮陽系數對夏熱冬暖地區(qū)建筑夏季能耗影響最大，節(jié)能率為53.17%，外窗和屋面的傳熱系數次之，節(jié)能率分別為50.15%、50.06%，外墻傳熱系數節(jié)能率為49.65%，對夏熱冬暖地區(qū)建筑節(jié)能不利；同時改善外窗遮陽系數以及屋面?zhèn)鳠嵯禂档母脑旆桨腹?jié)能率為53.28%，節(jié)能效果最好。, 分析廣州大學南向及西南向外窗遮陽構件遮陽效果，提出外遮陽構件的改進建議；通過實地調研及問卷調查的形式，對校園供冷期內房間舒適性以及校園能源浪費現象進行調查，，對空調系統(tǒng)與自然通風的結合形式、房間自然通風效果的改善以及行為節(jié)能工作的開展給出了建議。
[Abstract]:In recent years, the level of energy consumption in colleges and universities has increased. The energy consumption on campus mainly comes from the existing buildings with insufficient consideration for energy-saving design in campus. The existing buildings on campus are reformed to reduce the building energy consumption. It is the key to solve the problem of energy consumption on campus. In this paper, the energy consumption characteristics of existing buildings in hot summer and warm winter areas and the appropriate energy saving retrofit technology are studied and analyzed by combining the existing buildings in hot summer and warm winter with the energy saving technology of buildings. Taking Guangzhou University as an example, this paper analyzes the energy use level, energy consumption change law and building energy intensity of existing buildings in hot summer and warm winter area, and determines the teaching building, the energy consumption of student dormitory and library occupies a large proportion of the campus energy consumption and the energy consumption intensity is high. Is the campus building energy-saving transformation of the focus. Taking the teaching building of Guangzhou University as the research object, the influence of the thermal performance of the building enclosure structure on the energy consumption of the teaching building was studied by numerical simulation method. Through the comparative analysis of 15 energy saving renovation schemes, it is found that the sunshade coefficient of outer window has the greatest influence on building energy consumption in summer and summer in hot summer and warm winter area, and the energy saving rate is 53.17, and the heat transfer coefficient of outer window and roof is the second. The energy saving rates are 50.15 and 50.06, respectively, and the energy saving rate of external wall heat transfer coefficient is 49.65, which is unfavorable to building energy saving in hot summer and warm winter area. At the same time, the energy saving rate is 53.28 and the energy saving efficiency is the best for improving the shading coefficient of the outer window and the heat transfer coefficient of the roof. The paper analyzes the sunshade effect of the south and southwest windows of Guangzhou University, and puts forward some suggestions for the improvement of the external sunshade component. Through the form of field investigation and questionnaire survey, this paper investigates the comfort of the room and the waste of energy in the campus during the cooling period, and the combination of air conditioning system and natural ventilation. The improvement of room natural ventilation effect and the development of behavior energy saving work are suggested.
