Abstract: Good quality of lighting is believed to be closely related to the improvement of the students' performance and health. However, there are few researchers in this area of scholarship. The objective of this dissertation is to have better understanding of the relationships between the quantity and quality of lighting, and to develop a lighting quality index to evaluate lighting quality in Hong Kong classrooms. The hypothesis of the research is that interrelationships exist between qualitative measures related to student satisfaction and quantitative measures of lighting in classroom lit environment. A questionnaire survey and field measurement were conducted. The survey involved a sample of 485 local students from 15 classrooms in four schools in Hong Kong. The study revealed that not all selected schools satisfied the requirements in the CIBSE Code and Lighting Guide 5. The main problem of the existing school is the glare. This may directly influence the students' satisfaction. Meeting all the requirements in the codes and regulations does not guarantee the satisfaction level of the space, as the requirements are only the guidelines for the lighting designer. Factors affecting the satisfaction level are more the requirements stated in the codes and regulations. Veiling reflection may be the one of the factors. Colour temperature is one of the concerns of the students. Illuminance on the working plane is one of the major concerns in the codes and regulations. However, for the students, once the illuminance reached a certain point, no matter how much the illuminance increased, the satisfaction level is maintained at certain range. This is probably because of the human eye adaptation. In addition, in this study, a lighting quality index is established for the evaluation of the lighting quality in the classroom. The index can reflect the students' satisfaction with the lit environment.
