The indoor environmental factors considered in higher educational building must be determined in order to meet the user's requirement. Disruption of indoor environment may constitute to reduce occupants' efficiencies and their learning process and activities. But the question is, how to ensure that the provision of indoor environmental aspects achieves high satisfaction to the building user. Therefore, POE (post occupancy evaluation) is a prominent tool that indicates satisfaction and comfort level needs by the building occupants as lessons learned to identify problems in the indoor environment. The information of the building's condition is gained by reviewing what the occupants' feelings are and how they response to their needs by using and occupying the building. With relation to the title, the main aim of this study is to determine the occupants' satisfaction levels and the probability of learning process, which can be affected due to poor environmental conditions, based on analytical study on concept and process of POE. A survey on occupants' satisfaction of 100 students in University Technology of MARA, Perak, Malaysia, has revealed that there is significance of providing good quality of indoor environmental conditions, that will affect the learning process of the students. It is concluded that POE is effective to be used in evaluating performance of environmental conditions in a building, especially to apply the relative impact of aspects towards the design of future buildings. By introducing POE in evaluating environmental conditions in higher educational buildings, it is hoped that it helps to move the industry towards sustainable, healthy and comfortable learning areas.
