Post-occupancy evaluations (POEs) assess how effectively a space meets goals and supports activities through various data collection methods, including surveys and interviews. They help in measuring success, fostering evidence-based design, and ensuring continuous improvement by comparing pre- and post-occupancy data. Best practices include aligning assessments with project goals, incorporating both qualitative and quantitative data, and engaging neutral parties for analysis.

combine different assessment methods and use them to validate each
other and uncover further questions and insights.

tips for getting started
Here are some tips for getting started with post-occupancy
evaluations:
1. Whenever possible, get baseline
data from before the change
2. Work with experts on your campus,
such as your Office of Institutional
Assessment / Research
3. Have a neutral party conduct the
analysis so you get honest
feedback from users and un-biased
analysis
4. Report back to occupants to review,
validate, and act on findings, either
for that space or to inform
subsequent projects
