Post Occupancy Evaluation
Post Occupancy Evaluation (POE) is a structured review of the functional, operational and strategic performance of the building during occupation.
Post Occupancy Evaluation is the regular collection and review of:
- occupier satisfaction
- space utilization
- resource consumption
for the ‘normal use' of completed constructed facility during occupation to identify key occupier and/or building performance issues.
POE is used to assess how the built asset performs against defined ‘business' needs of the organization using that asset. This ‘in-use' intelligence is critical to drive better procurement, design, delivery and operation of the current facility and indeed others required within or outside the same organization.
A structured systematic POE process can answer several significant questions including: is the constructed facility and its occupiers operating as planned? If not, what corrective measures are necessary? And, how can buildings be better constructed in the future?
Key measurement tools/techniques include:
- Occupant survey questionnaires
- User Interviews and surveys
- Walk-though observations
- Metering & sub-metering
- Infra-red thermography
- Air permeability tests
- U-value testing
- Co-heating test
- Project completion reviews - often more ‘construction process' than ‘in-use operation'
What does POE cost?
Whilst not undertaking POE delivers ‘visible' short term savings, the ‘invisible' cost of not monitoring can be huge. Failure to collect and use POE data largely prevents an organization from making fully informed procurement decisions, risking inappropriate investment in a new facility when improving an existing one would deliver better results, or investing in complex technologies that do not deliver operational performance as expected/required.
Moreover, the cost of POE is almost insignificant when compared to the overall occupier's business operations costs - occupier's salaries etc. are typically 200 times the capital investment spread over 25 years - so it is critical the facilities maximize staff performance as well as minimize resource consumption. POE consistently costs considerably less than the savings and productivity gains it helps to deliver.
It is almost always the client organization that commissions and pays for occupancy evaluations, as they have the primary and ongoing commercial interest in optomised occupier & building (energy/technical) performance. However, a growing number of enlightened designers/constructors/suppliers see commercial value in independent in-use evaluations - as they can use lessons learnt to accelerate their internal continuous improvement programmes, and use evidence of high predictability of ‘in-use' performance to differentiate themselves in competitive markets.
