This paper investigates indoor environmental parameters and their interaction with building occupants in green-rated high-rise office buildings. Although the focus of Post-Occupancy Evaluation (POE) in green buildings has been shifted from building energy and environmental performance towards building occupants who are the primary users of buildings to identify a potential for increased produc-tivity in green buildings, the link between green design strategies – consequently indoor environmental parameters, and building occu-pants has not been fully identified yet. The methodology involves a systematic POE of four green-rated buildings in Seoul, Korea. By ana-lysing both physical measurement and occupant evaluation data col-lected from Korean office workers, this paper demonstrates the com-monalities and differences between objective physical conditions and subjective occupant evaluations. While the green-rated buildings have green features including solar panels, rainwater and grey water sys-tems, the most considerable features of green building such as natural ventilation and operable windows are not actively used. While the oc-cupant perceptions of the indoor environment seem to be correlated to each indoor environmental parameter of the buildings, some subjec-tive evaluations tend to show stronger correlations with other envi-ronmental parameters. Health symptoms such as fatigue, headache and dry throat tend to increase with ‘underfloor’ ventilation systems.
