ABSTRACT
This chapter shows that individual needs for people at work, because these are the conditions that will both reduce input costs and lead to increased output value. It deals with integrated recommendations for lighting that will support organisational productivity. The chapter suggests that lead up to this integration provide the necessary background understanding of the internal processes through which these needs might be met: sensation, perception, cognition, emotion. It reflects on the developments in both technology and knowledge, but also retains its grounding in the fundamentals expressed in the model of integrated lighting quality. Good lighting is achieved by simultaneously considering the effects of the lighting on the people using the space–bearing in mind that these may include a variety of individual needs and characteristics at one time –together with contextual factors relating to the architectural setting. The advent of light-emitting diodes has brought the potential for temporal luminous modulation back to workplaces.
