<p>The Baghdad Pearl gas station, which is located in a strategic location on a major highway connecting Baghdad and the northern and southern provinces on the one hand, serves as a vital rest stop for travelers and a filling station. Due to the lack of electricity on the external roads, it was proposed to design a solar system to operate an absorptive cooling system to provide a comfortable atmosphere in the rest building and prayer room at this station. This study investigates the dynamics of heat transfer in the building and the implementation of an advanced solar cooling system to enhance comfort and energy efficiency. The analysis reveals that the highest heat transfer occurs through the window glass (25312 W), followed by the ceiling (6660 W), walls (2712 W). The electronic control system integrated with the solar water heating system quickly heats the water, which greatly improves the efficiency of the system. The absorption cooling system works better because the control system makes sure that the hot water temperature is above 107 ^o C. Effective insulation reduces heat loss and heat exchange with the external surroundings, especially the foam laid under the roof tiles. Since the solar heating system does not require electricity, it is energy-saving and environmentally benign. Even in the hottest months of July and August, this system effectively cools the premises and maintains a comfortable atmosphere.</p>
