آلية تقييم تأثير حركة الشمس الظاهرية في مستوى الإضاءة ضمن الفضاء الداخلي باستخدام برنامج (Ecotectv5)‎ : دراسة تطبيقية على نماذج من أبنية رياض الأطفال في مدينة المحاويل

الملخص EN

The research reviewed the use of the outputs of (Ecotectv5) program by integrating maps of equal natural light lines within the internal and external space of models of kindergarten buildings in the city of Al-Mahaweel-with the aim of evaluating the effectiveness of the effect of the apparent movement of the sun on the one hand and the design and planning factors on the other hand in the level of illumination within the internal spaces in terms of-the comparison in the amounts of angles between the path of direct and virtual solar radiation in the direction of the lowest level of illumination within the interior space within the seasonal observations (winter and vernal equinox) and for three hours (830, 1030, and 1230), and the research reached a set of results that can be summarized as follows : custom building designs with the effectiveness of the factors that explain the level of variation in lighting for the spring observation-as the factor of the specific angles of the location of the sun disk within the path of its apparent movement, with a percentage of buildings that amounted to (66.7%), while the effectiveness of the design and planning factors of the level of illumination decreased in terms of the percentage of buildings, which amounted to (33.3%) for the observation hour 830, while the effectiveness ratio of the observation hour 1030 changed to reach (50%) for each of the planning and design factors, and the factor of specific angles for the location of the sun disk, while the third monitoring hour 1230, (50%) of the buildings participate in it of the design and planning factors, the factor of specific angles of the sun disk and (33.3%) of the buildings in which the effect of the design and planning factors is unique only.

the competent authorities should develop designs for the buildings to show the effectiveness of the effect of the factors that explain the level of variation of the natural lighting of winter observations within the interior space of models of kindergarten buildings in terms of the angles between the virtual solar radiation, and the path of the direction of the solar radiation towards a center of less light within the interior space of the buildings-as the factor of the sun disk site within the path of its apparent movement topped the percentage of buildings that amounted to (83.3%), while the percentage of the effectiveness of the design and planning factors decreased in terms of the percentage of buildings that did not exceed (16.7%) for the two monitoring hours 830 and 1230.
