The Impact of Measurable Findings from Pre- and Post-Occupancy Evaluations of Indoor Environmental Quality in the Primary Workspace

Abstract

This study examined the influence of quantitative and qualitative findings from both a pre-design occupancy evaluation (PDOE) and a post-occupancy evaluation (POE) on the expanded design team’s (designers, client, and researchers) approach to updating the interior work environment. The design team’s implementation of mid-course design solution modifications to the primary workspaces of an engineering group’s environment both after the PDOE and the POE yielded many significant outcomes. The POE was conducted using the same instrument as the PDOE one year after the employees had moved back into their renovated space on a corporate campus. The study’s results were used as a diagnostic tool to improve indoor environmental quality (IEQ) conditions for employees and provided benchmarks for the remaining (85%) campus workplace improvements. The influence and importance of IEQ criteria on employee satisfaction, work performance, and health were demonstrated and contribute to the body of knowledge regarding the influence of the built environment on building occupants. A paired inquiry (PDOE plus POE) helps ensure that human, financial, and environmental resources are appropriated with a higher likelihood of success over POE data alone in terms of meeting current and future employees’ needs and corporate goals.
