Today, solutions to reduce the energy consumption of buildings are fundamental to protecting non-renewable energy sources. A sustainable solution to protect nonrenewable resources is the optimal use of renewable resources, such as bringing as much daylight into the building as possible. The use of daylight, in addition to reducing the consumption of electrical energy, minimizes the load on the cooling system of the building. The optimal dimensions of windows are one of the important elements of the building, which is very effective in saving electricity and heat consumption. This study aims to optimize the consumption of electrical energy using daylight sensors. In this regard, the effect of daylight in reducing lighting consumption and reducing energy consumption has been investigated. This study was conducted in Tehran city. Then simulation method uses Energy Plus software to simulate and analyze the data. The results showed that the use of daylight, in addition to reducing the consumption of electrical energy, minimizes the load on the building’s cooling system: The amount of total energy consumption by energy carriers in the first stage (without using the Delight Sensor) is 72165.06 kWh and in the second stage (using the Delight Sensor) it is 53413.22 kWh, which reduces their energy consumption by almost 26%. A decrease of 66% was observed using the daylight sensor in the southern zone, while in the northern zone, it reached 76%. According to the ASE distribution diagram, the amount of glare near the windows, in the southern zone, was more than 2000 lux. According to the parametric analysis, the optimal ratio of the opening window to the surface is 20% in the southern zone and 30% in the northern zone.
