How does occupant perception on specific IEQ factors affect overall satisfaction

This study aims to develop a better understanding of the relationship between the perceived performance of specific IEQ factors and occupants overall satisfaction with their workspace, based on the hypothesis that the impact of an IEQ factor can differ depending on whether or not the occupants were satisfied with the IEQ factor in question. That is, a certain amount of increase or decrease in an IEQ factors perceived performance does not necessarily translate into commensurate increment or decrement in occupants overall satisfaction. Multiple regression analysis was conducted on the POE database from CBE (Center for the Built Environment) to estimate the impact of 15 different IEQ factors on overall satisfaction, depending on whether the performance on each IEQ factor was satisfactory or not. The results indicated that about half the IEQ factors had asymmetric effects on overall occupant satisfaction; these factors had a predominantly negative impact on overall satisfaction when occupants perceive that the building underperformed or was deficient in some way.
