Skylights or light wells are an integral part of the design of low- and high-depth buildings. The design of these skylights in different areas is based on specific criteria. According to Hamedan's criteria, only the dimensions of these skylights and the ratio of skylight area to height of the skylight are enough to design skylights. The purpose of this study was to evaluate the accuracy of skylights designed according to the existing regulations in Hamadan city and to estimate the optimum skylight dimensions to achieve the required space illumination and thus reduce the electrical energy consumption for illumination. To achieve this goal, studies were first conducted on daylight, solar energy, climate characteristics of the area, and standards on lighting. Then three buildings were selected as samples and in four seasons of the year, the illumination received in the spaces overlooking the skylight was harvested by a lux meter. Based on the studies, the amount of illumination was analyzed. Next, using simulator software, the dimming dimensions, modeled to achieve standard illumination, were modified. Finally, by changing the height parameter, the optimum dimensions of the skylight for one- to nine-story buildings were determined by the software. The results of this study showed that the existing criteria in Hamadan were not efficient and the light received by this system was not sufficiently implemented and new dimensions were introduced in this study.
