Performance indicators of Indoor Environmental Quality (IEQ) assessment in hospital buildings: a Confirmatory Factor Analysis (CFA) approach

Abstract

The study identified and validated the key indicators of IEQ parameters of measurement in hospital buildings. Four-factor parameters of IEQ were assessed; such as thermal quality, acoustic quality, visual quality, and indoor air quality (IAQ). Three public hospitals in Nigeria were taken as the case study areas for the IEQ assessment. The results indicated that IEQ parameters are represented significantly by the indicator variables in the hypothesised constructs. Thermal quality has three (3) main indicator variables, while acoustic comfort has two (2). Visual quality also has two (2) main indicator variables with IAQ having only a single indicator variable. The validation of these IEQ parameter indicators can be the basis for periodic assessment of IEQ performance in hospital buildings.
