Post Occupancy Evaluation (POE) is a process to investigate and analyze the operational performance of a green building in its occupancy phase, which compared the performance with predefined benchmarks such as predicted design goal, typical standard, and performance of similar buildings, etc. The process enable stakeholders of the building to learn design lessons, to identify concerns that need to be addressed, and provide feedback and knowledge to the green building industry. There are two components associated with Post Occupancy Evaluation - the building performance and building occupants. POE involves both qualitative methods such as occupant feedback and quantitative methods such as measuring energy use, indoor environment quality factors etc. to assess a building. Currently, there are several indicators and methodologies used to assess the two components of POE such as SB tool developed by iiSBE , CBE’s occupant IEQ survey ASHRAE building assessment guidelines, ISO Standards, SpEAR developed by Arup, BOMA BEST etc. The research team has set out to explore a number of different post occupancy evaluation schemes with the objective of identifying the right tool to be applied to CIRS. This report involves identifying the different assessment tools for the different building phases and types. It then moves on to identify the best standards to be used for post occupancy evaluation. Analysis is done on the best standards to identify strengths and weaknesses for each. Finally, a suitable set of indicators to assess the performance of a building is recommended.
