Abstract

Illuminance or lighting level is an important factor in ensuring conducive environment for studying in Malaysian public school. The design lighting level is based on the existing Public Work Department standard design which will help to evaluate on the daylight distribution in public school. However, despite the present of the existence PWD standard design, research still had to be carried out to determine, review, and identify the level of deficiency and improvement needed to be taken upon the PWD standard design to evaluate on the daylight distribution levels. This is because based on the current research related to illuminance value showed that there were some poorly lit spots within the classroom which are uneven that will affect the students’ performance. Based on this research study, analysis is carried out based on physical data and IES simulation software which enable to test the classroom under different sky conditions, orientations and time frame which allows the classroom to receive optimum daylight value.
