Abstract
Providing indoor environmental quality (IEQ) that satisfies building occupants is an essential component for sustainable and healthy buildings. Existing studies mainly analyse the importance of environmental factors on occupant satisfaction, but often overlook the influence of personal factors. Here, we aim to explore the influence of personal factors like life satisfaction, job satisfaction, the Big Five personality traits, sex, and age on occupant IEQ satisfaction. We conducted a cross-sectional assessment in nine air-conditioned commercial buildings in Singapore and surveyed 1162 individuals on their satisfaction with 18 IEQ parameters. Using proportional odds ordinal logistic regression we found that occupants with higher job and life satisfactions were, respectively, 1.3 – 2.3 and 1.3 – 2 times more likely satisfied with the 18 IEQ parameters. The odds ratios (OR) for overall environment satisfaction and job and life satisfaction were 2.1 (95% CI: 1.8 – 2.6) and 1.9 (95% CI: 1.6 – 2.3). We speculate that occupants’ satisfaction with their job and the overall environment are entwined, meaning that better workspace could improve job satisfaction and vice versa. We observed some associations between the Big Five personality traits and some IEQ parameters, but the corresponding effects were small. Due to the substantial relationship between job and overall workspace satisfaction observed in this study, we recommend including job satisfaction questions in future post occupancy evaluations (POEs).
Introduction
A building’s success is often determined by how well indoor environmental quality (IEQ) supports the occupants within it. This type of success typically is measured by assessing how satisfied occupants are with distinct elements of their environment or the overall space [1,2]. For example, perceptions of thermal comfort, lighting, air quality and acoustics are known to influence overall environmental satisfaction [3–7]. And these perceptions can be tied to measurable physical parameters (e.g., temperature, illuminance, carbon dioxide concentration and sound pressure levels). For instance, architectural parameters such as office type, spatial layout, desk location (distance from window), window view, amount of available space, comfort of one’s furnishings, space cleanliness, façade design, window to wall ratio and building orientation also show a strong relationship in predicting environmental satisfaction [8–12].
