Building performance evaluation v post-occupancy evaluation

Building Performance Evaluation (BPE) is a form of Post-Occupancy Evaluation (POE) which can be used at any point in a building's life to assess energy performance and occupant comfort and to make comparisons with design targets.

Post occupancy evaluation (POE) is the process of evaluating a completed development to determine:

  • How successful its delivery was.
  • How successful the completed development is.
  • Where there is potential for further improvement
  • What lessons can be learned for future projects.

BSRIA suggest that “Post-occupancy evaluation (POE) constitutes the activities of the BPE process once the building is occupied and in use, focussing on the operational performance and the occupants of the building. It is important to know to what extent the building maintains its occupants’ satisfaction and perceived comfort. To do this in a systematic and structured way, post-occupancy evaluation (POE) can be employed as a major part of BPE. This would involve collecting feedback (soft data) from the occupants through survey questionnaires, interviews and / or workshops, ideally at least one year after building occupation to cover at least on seasonal cycle.”
