摘　　要：实验室的采光条件直接影响实验的顺利进行以及实验结果的准确性。该文从采光的形式出发,整理了窗户尺寸、窗地比、玻璃透光率以及遮阳形式等4个室内光环境影响因素,基于Ecotect软件对不同影响因素进行室内光环境模拟分析,通过计算采光系数和采光均匀度定量分析各因素对室内光环境的影响程度,为实验室类建筑改造提供科学依据。[Objective]Daylighting plays a vital role in research laboratories to meet the needs of daily research.Through in-depth investigation and detailed analysis of the Digital Habitat Laboratory of Hefei University of Technology,insufficient light intensity was observed inside the laboratory,especially in the areas away from windows.Additionally,severe glare occurred near windows at noon.To achieve a better understanding of the factors influencing indoor daylighting conditions,we combed the relevant literature and identified four key factors:window size,window-to-ground ratio,glass transmittance,and sunshade measures.Additionally,to explore the specific impact of each of these factors on daylighting,more in-depth research must be conducted to obtain accurate and scientific references for constructing and renovating relevant research laboratories.[Methods]We used the Ecotect program to simulate and analyze several influencing factors.First,the original size of the laboratory side window was used as a benchmark to establish standard reference data.Next,daylighting data were collected when(a)the window width was adjusted,(b)the number of windows was increased,(c)glass was replaced with various materials,and(d)various sunshades were used.Finally,an in-depth quantitative analysis of daylighting data was conducted at three distinct indoor positions near the windows.[Results]Quantitative analysis of the data revealed that when the width of the side window was controlled at 1,100 mm,the indoor daylighting coefficient performed well,and a moderate increase in the window size had less impact on indoor light uniformity.However,after the size exceeded 1,200 mm,it excessively illuminated the area near the windows,which is not conducive to the working environment needs of the laboratory.Moreover,the window-to-ground ratio has a proportional relationship with the indoor lighting coefficient and the illuminance value.As the window-to-ground ratio increased,the indoor lighting area accordingly expanded,improving the indoor illuminatio
