Indoor Environmental Quality Determinants in the Buildings

Abstract

Abstract The presented aim of this study is to establish or reject the correlation (relationship) between the individual indoor environmental quality indicators and the total satisfaction with the indoor environment. The subjective satisfactory survey has been performed in 10 standardized university classrooms (Czechia) to evaluate the indoor environmental quality (IEQ). The IBSM SPPS Software Statistics ver. 25.0 was used to assess the Kendall non-parametric correlation analysis. Seven individual different indoor environmental quality indicators evaluating by subjective perceptions of the users were reviewed: air acceptability, thermal comfort, humidity comfort, odor comfort, acoustic comfort, visual comfort, and color comfort. The user’s subjective perceptions of the indoor environment were collected by questionnaires. Minimizing the ability to adapt and acclimatize was desirable. The statistically significant correlation (P < 0.01) were observed between the air acceptability (τb= 0.249), the odor comfort (τb= 0.260), the acoustic (τb= -0.244), the visual comfort (τb= 0.203), and the colour comfort (τb= 0.192) and total satisfaction with the indoor environment. The thermal comfort and the humidity comfort are not statistically correlated with the total satisfaction of the indoor environment (P > 0.01).
