Lighting electricity consumption accounts for about twenty percent of all electricity in Taiwan. Time of the electricity usually used in schools is during the peak demand hours of electricity power system. So, it will help on energy-savings by improving classroom lighting. In addition to energy-savings, classroom lighting quality affect students' eyesight very huge; therefore, how to choose classroom lampswith both high energy efficiency and good lighting quality is important. In this thesis, eleven lamps with different luminous intensity distribution curve are layouted for lighting simulation by DIALux lighting software. A testing simulation classroom was selected to be lighted by eleven test luminaires and simulated by DIALux with a average luminance of 550±50Lux be a design goal. Lighting attribute values obtained by DIALux are further more analyzed by a multidimensional scaling method (MDPREF) to get the choice ranking of classroom luminaires.The result shows that lamps’ ranking affected by the altitude change is not obvious, and the semi-direct lighting lamps, semi-indirect lighting lamps, and commonly used Yamagata LED lamps have the better performanceinlighting quality and energy efficiency.We recommend semi-direct lighting is worth promoting.
