【摘要】：我國是世界上能源需求增長速度最快的國家之一,已經(jīng)成為僅次于美國的第二能源消費大國,節(jié)約能源具有重大意義。天然光利用一直是建筑可持續(xù)發(fā)展的重要方面,不僅可以有效降低照明用電能耗,節(jié)能潛力巨大,還對于營造舒適、健康的環(huán)境也起著重要作用。辦公建筑是我國公共建筑的主體,考慮到城市土地資源的逐漸稀缺、以及大進深辦公建筑的逐步流行,大進深大空間的采光正越來越得到重視。綜上所述,本文將研究課題定位于大進深辦公室的天然采光與人工照明節(jié)能關(guān)系的研究。 本課題主要從五個方面展開研究： 第一,側(cè)面采光影響因素分析。首先,探討本課題的研究對象辦公建筑所具有的分類；其次,敘述辦公建筑的采光形式；然后,分析在不同采光口形式下的采光性能； 第二,軟件分析部分。針對不同軟件進行對比分析,確定Daysim作為動態(tài)采光模擬和Diva for Rhino作為采光系數(shù)的模擬計算工具。 第三,辦公建筑采光節(jié)能的分析方法,分析不同影響因素對全年采光水平的影響,如室內(nèi)表面反射比、窗的總透射比、朝向、窗戶形狀、窗臺高、進深等。 第四,參照《建筑采光設(shè)計標(biāo)準(zhǔn)》GB50034-2013版的研究方法,列舉出共計231個房間組成的辦公空間集合,研究231個房間的采光節(jié)能潛力系數(shù)k,采光節(jié)能潛力系數(shù)k主要依據(jù)DA450,描述房間全年所具有的采光節(jié)能潛力。 最后,分析部分利用采光區(qū)域的范圍。 本文的采光分析是基于房間或建筑全年采光水平,將全年采光水平與節(jié)能分析相結(jié)合本文的研究思路。根據(jù)以上四個方面的研究,本文結(jié)論主要包括： 第一,大進深房間的采光及采光節(jié)能問題應(yīng)該得到重視。 第二,比較計算結(jié)果后發(fā)現(xiàn),窗口形狀及位置、建筑層高、房間朝向?qū)Υ筮M深房間的全年采光水平影響最大。 第三,房間窗地比、窗的總透射比與DA450平均值之間存在線性關(guān)系。采光節(jié)能潛力系數(shù)k會隨窗寬比和窗高比的增大而增大,隨著進深的增大而減小,且進深越大,采光節(jié)能潛力系數(shù)k值的下降趨勢會減小。
[Abstract]:China is one of the fastest growing energy demand countries in the world, which has become the second largest energy consumption country after the United States, so it is of great significance to save energy. The utilization of natural light has always been an important aspect of the sustainable development of buildings. It not only can effectively reduce the energy consumption of lighting, but also plays an important role in creating a comfortable and healthy environment. Office building is the main body of public buildings in our country. Considering the scarcity of urban land resources and the popularity of office buildings, the daylighting of large depth and large space is being paid more and more attention. In conclusion, this paper focuses on the relationship between natural lighting and artificial lighting. This topic mainly carries out the research from five aspects: First, the influence factor analysis of side lighting. Firstly, the classification of office buildings is discussed. Secondly, the daylighting forms of office buildings are described. Second, the software analysis part. According to the comparison and analysis of different software, Daysim is chosen as the simulation tool of dynamic lighting and Diva for Rhino as the simulation calculation tool of lighting coefficient. Third, the analysis method of office building daylighting energy saving, analyzes the influence of different factors on the annual lighting level, such as indoor surface reflectance, window total transmittance, orientation, window shape, window height, depth and so on. Fourth, referring to the research method of the GB50034-2013 edition of Building Lighting Design Standard, the collection of office space consisting of 231 rooms is listed. The energy saving potential coefficient k of 231 rooms is studied, and the energy saving potential coefficient k is mainly based on DA450, which describes the energy saving potential of the room in the whole year. Finally, the range of daylighting area is analyzed. The daylighting analysis of this paper is based on the annual daylighting level of the room or building, combining the annual daylighting level with the energy saving analysis. According to the above four aspects of the research, the conclusions of this paper mainly include: First, the lighting and lighting energy-saving problems should be paid attention to. Secondly, it is found that the shape and position of window, the height of building floor and the orientation of the room have the greatest influence on the annual lighting level of the deep room. Thirdly, there is a linear relationship between the window / floor ratio, the total transmittance of the window and the DA450 mean value. The energy saving potential coefficient k will increase with the increase of window width ratio and window height ratio, and decrease with the increase of depth, and the decreasing trend of the coefficient k will decrease with the increase of depth.
