Investigating the design of educational space with the approach of reducing stress using biophilic design

Today, learning various sciences has become one of the basic needs of humans, and there are many obstacles that reduce the speed of learning; among these obstacles, we can mention stress. Stress is a kind of response to emotional or physical changes created in the environment and living conditions of students, which can appear in different ways according to their age, life situation, and personality. If the learning space is designed properly, it can eliminate a lot of stress in students. Reducing stress in students can lead to discovering their hidden talents, increasing self-confidence and making the most of their potential, which will increase learning. Also, various studies have been conducted in western and other countries about the effect of architecture on reducing the stress of users, a limited number of which have been conducted on the effect of the architecture of the educational space on reducing stress with different research methods and approaches, each of which has research problems and flaws in two areas. They are thematic and methodological knowledge. The research showed that various studies have been conducted in the three fields of environmental psychology, psychology and architecture of educational spaces, but no sufficient and accurate studies were found about the interrelationship of these three topics. With quantitative and qualitative approaches, this research aims to deal with the subject in the two scientific fields of psychology (stress, stress theories) and architecture (psychology of the environment of educational spaces, architecture of educational spaces, health and architecture, etc.). The purpose of the present research is to identify the physical factors that are effective in reducing the stress of students in the educational spaces of the school, which is a factor for the scientific progress and improvement of the country and is associated with increasing the productivity of schools. This research aims to evaluate the effect of physical and non-physical dimensions of stress reduction on stress reduction in combined research (description of the survey type and logical reasoning).

With the help of the Delphi method, the experts in the field of architecture were asked to categorize the practical physical factors of stress reduction. Then, the test analysis was done with the help of hierarchical analysis (AHP).

After the complete hierarchical analysis, at first, the main criteria were ranked according to the goal, and then the sub-criteria were ranked in details, and the percentage of importance of each was determined. Among the main criteria, the combination of nature and environment gained the most weight, with a weight of 0.534, so it was the most important among the main criteria. The criteria for modeling nature and the spatial characteristics of the environment were also in the following ranks. A pairwise comparison of the sub-criteria of the integration of nature and the environment and their order of importance was discussed, and it could be seen that the sub-criteria of light with a weight of 0.541 took the first place, and the sub-criteria of plants and natural landscapes and ecosystems were in the following ranks.

In designing a conservatory with the approach of reducing stress through biophilic architecture, light is the most critical design factor, and then the plants inside and outside the environment, natural landscapes, and ecosystems should be observed in the design.
