Building Environment Science I (Lighting) focuses on architectural lighting design especially on three fundamental aspects of the illumination of the built environment. The first is the ergonomic aspect: the measure of how the function of that environment influences the lighting design and light will affect the health and comfort of the people living and/or working in that environment. Secondly is the energy efficiency issue to assure that light is not wasted by over-illumination. Thirdly is the aesthetic appeal of a building. Having successfully completed the module, students will be able to demonstrate knowledge and understanding of: i. Light properties (Photometric properties, quantities & definitions of light sources ii. Heat transfer, solar radiation, and their relationship to building performance  iii. Typical and potential applications of these light sources, which is integrated to architectural designs.
