This paper reports a post-occupancy evaluation study of a LEED Platinum building on a university campus. A multiple-tool POE approach with GIS-based spatial mapping method was used to analyze and visualize the survey results of building occupant satisfaction and the measured indoor environment quality. The occupants were overall satisfied with the indoor environment in their workspaces in the building of study, though thermal comfort was comparatively low with high percentage of occupants reporting their workspaces too cold. Air movement was found to be lower than preferred by the occupants, especially in interior offices where CO2 level was also predominantly higher. Light levels in the building were found higher than preferred. Electric lighting power density installed did not reflect the fact that daylight is available for most of the lab and office spaces. Satisfaction with speech privacy was found lower in individual offices related to the construction detail of the connection between curtain wall and interior walls. Linking performance outcomes with spatial information improves POE data management. Spatial mapping allows reasons that cause occupant discomfort and dissatisfactory measured performance to be identified more intuitively and makes it potentially easier to communicate POE results with architects, engineers and facility management professionals, in order to engage them in the collaborative effort of continuous building performance improvement.
