Oxin project is defined as an industrial plant with metal works activity in Ahvaz city. The project land includes two major activities within it: Production industrial sector Administrative sector The idea of the project is to create a large shade on the administrative part of the project. A canopy that reduces the heat of the sun by creating a shadow under it and also causes a temperature difference in the space under it to increase the air flow in different spaces of the complex. In the geographical climate of Ahvaz, creating shadows along with creating small lighting in front of the sun and creating temperature differences in semi-open spaces are among the common methods of this region. Due to their geometry, the roofs have been able to create natural light in the entire shed without creating too much heat inside the sheds. The type of openings in the roof of the shed also helps in creating air flow inside the shed. The roof formed in the office section also has small openings on it that are meshed with wooden openings that direct the air flow from inside and also control the sunlight through the wooden openings. The physical idea of the plan is to create gaps in the mass of the whole project so that exposure to different spaces is formed through these gaps to be a method for exposure in spaces where the sun's radiation causes heat. Therefore, three-meter light concrete panels with a one-centimeter layer of hard concrete were designed in this project, which will be used in the entire project.
