    Completing the missing link in building design process: Enhancing post-occupancy evaluation method for effective feedback for building performance
    (Pergamon-Elsevier Science Ltd, 2015) Gocer, Ozgur; Hua, Ying; Gocer, Kenan
    This paper provides a review of the improvements in the evaluation of building performance and introduces a new method for post-occupancy evaluation (POE) to complete the missing link in the building design process. Existing studies were reviewed to understand the possible reasons for the missing link of building performance feedback. The intention of this paper is to set out a new vision for how future post-occupancy evaluation can close the building performance feedback loop to better inform building design. The spatial mapping method adopted extends the use of building information modeling (BIM), which has shown great potential for the future of the Architecture, Engineering and Construction (AEC) industry, and uses geographical information systems (GIS). which is a powerful tool for analyzing and visualizing relationships between geographical units and their data. This study explores how to establish a communication platform for different stakeholders in order to engage them in the collaborative effort of continuous building performance improvement by using the results of POE embedded into BIM. In this paper, the experiences of a POE study of a LEED Platinum building and a historical building on a university campus are reported as examples to illustrate the proposed new method.

    Spatial mapping of occupant satisfaction and indoor environment quality in a LEED platinum campus building
    (Pergamon-Elsevier Science Ltd, 2014) Hua, Ying; Gocer, Ozgar; Gocer, Kenan
    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.
