A Post-Occupancy Evaluation of the Impact of Indoor Environmental Quality on Health and Well-Being in Office Buildings

Abstract

Post-occupancy evaluations have been recognized for documenting occupant well-being and responses to indoor environmental quality (IEQ) factors. Sustainable Post-Occupancy evaluation survey (SPOES), a self-administered and internet-based questionnaire, provides a quantitative analysis of occupants’ satisfaction. Employees in Building A (N=75), B (N=69), and C (N=76) rated their satisfaction about 12 IEQ criteria and the impact of built environments on their health. Indoor air quality, furnishings, electric lighting, daylighting, and vibration/movement IEQs ranked highest on the impact on health. These results imply that 12 IEQs are highly related to employees’ perception of how the built environment impact their health. The IEQs offer an opportunity for improving occupants’ well-being and built environments.
