This series of tutorials takes a unique approach to interior lighting design in that it tackles the essential information used directly in lighting design calculations; the first tutorial tackled the Zonal Cavity Method of lighting calculations while this course addresses how to determine or calculate the light loss factors (LLF) that act to diminish the amount of light available to the tasks and activities taking place in the lit area. Understanding and knowing how to determine the LLFs that affect a lighting system is necessary to ensure adequate levels of illumination are maintained over the lifetime of that lighting system. This course covers three main LLFs but will briefly address other LLFs that exist. The author knows from experience that there is a lot of knowledge that goes into a good, quality lighting system that meets the objectives of providing appropriate light levels for the tasks to be lit. In this course the attendee learns how to calculate the three primary LLFs known as the lamp lumen depreciation (LLD), the luminaire dirt depreciation (LDD), and the room surface dirt depreciation (RSDD) which can then be used in the lighting calculations of that first tutorial. Subsequent courses will cover topics such as selecting the light sources, the fixtures and the ballasts to be used and other topics such accounting for circumstances that affect the qualitative aspects of a lighting design.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
