The Exploring of the Importance of Indoor Environmental Factors in University Educational Spaces Based on Participants' Psychology

The comfort feeling of human body to indoor environment is a comprehensive reflection of multi-factor interaction. The research on human comfort is developing from single factor to multi-factor interaction. At present, the research on indoor environmental quality (IEQ) is limited to the single IEQ domain of heat, sound, light and air quality or the interaction of environmental factors between two IEQ domains, while the research on the relationship between comfort and psychological emotion is relatively scarce. Based on this, this paper takes the education space related to the art museum and college student activity center of Shandong Jianzhu University as the research site, uses PGWB-S questionnaire to determine the recent psychological and emotional status of college students, selects 16 common environmental factors, and uses Likert scale and principal component analysis to score the indoor environmental quality expectation of college students under different psychological and emotional conditions. The results show that the people with low expectation of indoor environmental quality are often the people with poor psychological and emotional status, and vice versa. Further research shows that most of the people who have high expectations for the comfort of indoor space-related factors are the people with poor mental and emotional status, while the group with good mental and emotional status is more inclined to good indoor heat, sound, light and air quality. Based on the psychological status of participants, this paper obtains the expected IEQ of different groups, which provides certain data support for the study of the relationship between indoor environment personalized design and psychological and emotional status and comfort level.
