The most fundamental aspect of designing with light, and lighting controls, is how we perceive the interaction of light and surface in the built environment. When intentionally designed, we can use these interactions to direct attention, create mood, regulate the awareness of brightness, and improve occupant satisfaction all while minimizing energy use.
Current research shows us that learning about visual perception is not enough. Light also has specific physiological impacts that must be considered in most projects. How does light affect alertness? What kind of light do we need for our sleep wake cycles? How does light affect our endocrine systems? Are LED light sources really hazardous? How may lighting controls help us with these issues?
