PurposePost-occupancy evaluation (POE) of office buildings, accommodating large number of users, is significantly demanded, to ascertain the provision and upkeep of users' requirements. This paper presents the findings of a POE of an office building located in Saudi Arabia, as a case study.Design/methodology/approachA mixed approach of qualitative and quantitative research activities were conducted to achieve the objective of this study. Previous studies were analyzed to identify 28 performance indicators, grouped under seven technical and functional performance elements in office buildings. A walkthrough served to gain familiarity with the building, and identify the obvious performance defects. Interviews were conducted to solicit the users' perceptions about the performance elements, and initiate discussions based on the findings of the walkthrough. A user satisfaction survey was then deployed to quantify the user's feedback on the performance of the building.FindingsUsers of the case study office building were generally satisfied with all the technical performance elements, except visual comfort. They were also dissatisfied with two functional performance elements, namely office layout and building equipment.Practical implicationsRecommendations were developed to improve the performance of the case study building. The approach followed and the defined indicators can be of practical value to design professionals, administrators and facilities managers, responsible for the design and operation of office buildings.Originality/valueOffice buildings are valuable business capital for their corporate organizations. This study contributes to the facilities management literature, through providing a systematic approach for the quality and performance appraisal of the performance elements of office buildings.
