Lighting is a large and rapidly growing source of energy demand and greenhouse gas emissions. A considerable part of the population in the industrialized world spend their working hours in offices. Lighting is a substantial energy consumer and a major component of the service costs of offices. The primary function of office lighting is to enable workers to perform their tasks comfortably and safely. On the other hand, with the increase in the price of energy more attention is being given to energy- efficient lighting. Only a small percentage of the population in developing countries has access to electric lighting and the rest use fuel-based lighting for their basic lighting needs. The main goal of the international cooperation for more efficient use of lighting energy is to identify and to accelerate the widespread use of appropriate energy efficient high-quality lighting technologies and their integration with other building systems, making them the preferred choice for lighting designers, owners and users.
