description	A great understanding of the factors that influence thermal responses to human comfort and the low energy consumption is very important. It has been confirmed that factors not related to the thermal environment can affect the thermal responses of occupants. However, these factors have not been investigated and studied in more detail especially under different environment conditions due to a lack of knowledge of indoor environment factor interactions. Therefor, accurate and high-quality data of light intensity is highly important to focus on. Accordingly, the current project focuses on the influences of light intensity on the temperature, air velocity and humidity of the indoor environment were studied and investigated under natural and controlled environment conditions. The main objectives are to investigate and evaluate the various affections of light intensity parameters on indoor room temperature and humidity and to develop a simulation model of the indoor environmental condition. Hence to achieve the over mentioned objectives, there are three main stages of our study, (Stage 1) a comprehensive review of the previous studies have been conducted to specify the gap for light intensity effect on the indoor environment. Then, in (Stage 2) a complete design and simulation performed using the ANSYS platform, wherein this stage we measured the most important parameters such as indoor temperature, air velocity, and humidity. In (Stage 3), the experimental work was implemented by designing a room environment prototype with dimensions of (Im x1m x1m) and bifurcated, then the simulation analysis was performed to obtain the results. The experimental work was introduced by changing the type of lamps and light intensity. It followed with a significant questionnaire on the effect of the light intensity on visual comfort. Based on the results obtained from simulation analysis and experimental work, the halogen lamps have more effect on the indoor environment parameters than the LED lamps, but it has less visual comfort. In conclusion, the light intensity is directly proportional to.the indoor temperature and air velocity while the humidity is inversely proportional. Moreover, the high light intensity affected negatively the visual comfort and psychological comfort of occupants. Finally, the project outcome can be considered as a reinforcement step in emphasizing the actual effect of lighting intensity and the required lighting must be in accordance with the daily duty.
