Lighting design varies significantly for space to space. Each lighting design problem could be addressed in varies ways to suit the lighting objectives. Thus, awareness on energy efficient lighting design concepts is recommended over fixing set rules for energy efficiency lighting design. The three major objectives of a good lighting design are:
- Health and safety requirements: The design objective should target a well-lit space to work in safety. The design should prevent eye strain, glare, and any harmful radiations.
- Lighting output and energy use: Based on nature of use, functional requirement, age of user, colour discrimination etc., the lighting conditions are set for the design and associated energy use is maximized.
- Appearance and comfort: The lighting design is governed by the overall desired appearance of the object or space within it. The objective is expressed based on certain physical parameters like desired mood, atmosphere, safety factor, visual task etc.
