Investigation of the Effects of Using Water-Wall on Glazing in the Western Facade of the Buildings with a Moderate and Humid Climate

Nowadays, due to the fact that people spend a significant percentage of the day hours in closed environments, providing quality natural light in these spaces will be essential. On the other hand, one of the important challenges of direct light entering space is the issue of glare, which requires fundamental considerations. The current research is trying to use the western front for natural light by providing solutions to create visual comfort. The basic question is: To what extent is the water wall in the west wall effective in improving visual comfort conditions from the perspective of glare? To what extent is the fluid color between the wall and the dimensions of the water wall effective in reducing glare? Following the steps of the research, by simulating the basic model in "Rhino" software, specifying the values of variables and entering data in "Grasshopper" software, and using "Ladybug" and "Honey Bee" plugins, the results are obtained. It has been compared in a comparative way. On the other hand, there is a direct relationship between the reduction of glare despite the fluid pigment and the reduction of the dimensions of the water wall. The results indicate that the water wall with 0.36 units, the water wall with blue color with 0.32 units, and the water wall with the same area of the window with 0.3 units have had a significant decrease.
