Daylighting and visual performance: evaluation of classroom design issues in the UAE

摘要

The study focuses on analysis of visual performance and quality issues in classrooms located in the United Arab Emirates (UAE). The methodology depended on data collection and analysis of design information obtained from architectural drawings of standard schools, design compliance documents set by the relevant governmental bodies, and site visits and photography. It analyzed several important design issues that have significant impact on visual quality, including space size and depth to height ratio, windows orientation, lighting direction and desk position. It used simulation to investigate potential visual problems during critical times and view angles. Several problems concerning contrasting luminance levels in the field of view were identified and described. Mitigation of the problems using recommended daylighting systems was discussed based on the UAE climate.
