The University of Mosul has recently witnessed a construction of several departments, administrative buildings and lecture halls which may suffer after occupation some environmental or functional problems that require deep studies and researches to diagnose those problems, Hence comes the importance of post occupancy evaluation studies of those buildings as an integral part of the planning , design and construction processes to explore what is positive and negative in the design process , and get benefit from such researches to adopt the positives to enrich the design process and stand on the negatives and their causes to find an appropriate solutions and avoid repeating them in the design of future buildings.
The problems stemming from the indoor environmental quality in the lecture halls comes at the front of these negatives and in particular the daylight and the use of it to enriches the indoor environment and it is supportive impact on students and lecturers performance and psychological health on one hand and the rational consumption of energy expended on artificial lighting on the other.
This study focuses on the post occupancy evaluation of daylighting in the lecture halls at the new buildings of the University of Mosul, and the college of Electronic Engineering has been chosen as a case study because the adoption of one typical design to all of its four departments and replicated in other locations. The study reveals a deficiency of utilization of daylight as a design factor to provide visual comfort for the occupants of these buildings through the cognitive and realistic measurements adopted for this study.
