Post-Occupancy Evaluation
Also known as: POE, building performance evaluation, occupant satisfaction assessment
Post-Occupancy Evaluation (POE) is a systematic method for assessing how well a completed building meets the needs and expectations of its occupants, comparing planned performance to actual performance. Formalized by Wolfgang Preiser in the 1980s, POE has become essential for learning what design strategies work, identifying problems for remediation, and improving future projects.
Key highlights
- Bridges the gap between design simulation and actual building performance; reveals where predictions were inaccurate
- Captures occupant perspective: whether people are satisfied, how they actually use spaces, what problems they experience
- Identifies quick wins: low-cost operational changes that improve performance without capital investment
- Provides data for design feedback: architects and engineers learn what strategies work, enabling better future projects
- Supports institutional learning: consistent POE methodology creates comparable data across multiple buildings

When to use it
Conduct POE on significant buildings (especially public or institutional) to document outcomes, diagnose problems, and guide strategic improvements. It is particularly valuable after implementing energy-saving measures or for buildings with poor perceived performance. Institutions increasingly require POE as part of building accountability and continuous improvement.
Strengths & limitations
- Bridges the gap between design simulation and actual building performance; reveals where predictions were inaccurate
- Captures occupant perspective: whether people are satisfied, how they actually use spaces, what problems they experience
- Identifies quick wins: low-cost operational changes that improve performance without capital investment
- Provides data for design feedback: architects and engineers learn what strategies work, enabling better future projects
- Supports institutional learning: consistent POE methodology creates comparable data across multiple buildings
- Time and cost: comprehensive POE is expensive; limited scope may miss important problems
- Occupant bias: satisfaction is subjective; some respondents are more vocal than others, skewing results
- Causation is hard to establish: if energy consumption is high, is it due to building design, operation, occupant behavior, or external climate?
- Timing: conditions change over time (building ages, occupancy evolves, systems degrade); evaluation at one time point may not be representative

Frequently asked
Why does my building use more energy than predicted, even though the HVAC system performs as designed?
Design predictions often assume standardized occupancy and control. POE reveals actual patterns: longer operating hours, higher setpoints for comfort, unpredictable equipment use (plug loads), or occupant behavior (opening windows in winter). Operational changes often close the gap more cost-effectively than physical retrofits.
How can I encourage occupants to participate in a POE survey?
Timing, incentives, and communication matter. Survey during work hours when participation is feasible; offer small incentives (entry into gift drawing, coffee vouchers); clearly communicate how results will be used. Digital surveys have higher completion rates than paper. Response rates of 40-60% are typical and generally representative.
Should I measure occupant satisfaction with a standardized tool or design my own questionnaire?
Use existing validated instruments where possible (Building Use Studies comfort questionnaire, BUS Scale) to enable comparison across buildings and projects. Supplement with site-specific questions addressing particular design decisions. Combining standardized and custom questions gives both comparability and relevance.
How do I distinguish between design problems and operational problems?
POE combines physical measurements, occupant feedback, and operational data. A cold space might be caused by poor insulation (design), wrong thermostat settings (operation), or occupant behavior (opening windows). Measurements of temperature, heating energy, and window opening behavior help isolate the root cause.
