Evaluation of buildings and their environments has an effective role in the building process in order to assess the efficiency of designed environments. Both at the academic and professional level, the most practical, systematic and effective feedback tool available for building evaluation is post occupancy evaluation This thesis aims at assessing this systematic technique from the point of view of building values, pointing out deficient aspects, and developing an alternative model. Rather than changing the nature of POE, the objective is to bring a new approach in order to make the context of POE more comprehensive and useful. The criteria used in POEs conducted so far is gathered by the use of some typical case studies. A brief analysis of current studies showed that all the aspects evaluated by POE are somewhat technical in terms of building performance, user satisfaction, and overall effectiveness of the building. A comprehensive POE should go one step beyond building performance, and add new aspects into its context in order to meet the need for useful design guidelines of wider perspective. Thus, building values and defined criteria are integrated into POE, regarding its deficient parts in specific cases, and programmatic needs. An alternative POE model is proposed, and the applicability of this model is tested by the use of a pilot study. As a result of this study, it is concluded that the new model is quite effective in evaluating buildings according to social, cultural, contextual, and perceptual criteria. POE can be more comprehensive by integrating alternative criteria into this system. Further studies would broaden the perspective of POEs by focusing on new trends and new values in the highly accelerating building industry.
