Multi-objective optimization of visual and thermal comfort in classrooms as a function of room dimensions and proportions (case study : secondary high schools in Tabriz city)

The complexity of the design and the abundance of aspects that must be considered simultaneously by designers make it necessary to pay attention to different variables, which leads to the optimization of different functions. Other results of studies in this area are the identification of different variables. This study aims to investigate the effects of the dimensional variables and the ratio of area to volume of the classroom on the visual and thermal comfort of the users. For this purpose, the performance of the model in terms of the variables of and thermal comfort was investigated based on the weather data of Tabriz city using the simulator plugins Honeybee and Ladybug and the optimization plugin Octopus based on the evolutionary algorithm. The results of the survey show that the area-to-volume ratio of desired classrooms ranges from 1.16 to 1.69. The outcomes deemed optimal for the objectives of glare probability and daylight autonomy suggest that the most favorable solutions lie within the lower range of the surface area-to-volume ratio. Conversely, concerning comparative thermal comfort, the optimal solutions are found within the upper portion of the aforementioned range.
