ANALYZING THE RELATIONSHIP BETWEEN THE INDOOR AIR ENVIRONMENT AND SUBJECTIVE ASSESSMENT OF IAQ BY GREY SYSTEM

摘要

The essential objective of a building should be to provide a safe, healthy and comfortable environment for occupants. Sometimes, however, the consistency of indoor air contamination appears to be higher than that of outdoor air because of poor ventilation. The influence the indoor air contamination exerting on us is characterized, as complexity, long-term effect and the low concentration will influence human body simultaneously. In this article, Grey system incidence theory is used to analyze the relationship between parameters of indoor air environment and subjective assessment. In this analysis the concentration of contaminations determined objectively is connected with people's (subjective) feeling, thus, the prominent contamination which influences people most will be found out.
