This position paper provides an overview of the lighting technologies market for non-residential buildings, outlining its importance, potential, and development. It addresses issues for policy- and decision-makers and other stakeholders aiming to support the implementation of energy-efficient, sustainable, and integrated and integrative lighting solutions. It concludes by highlighting existing challenges and the actions needed to best exploit energy efficiency and decarbonization opportunities.

Daylight plays a key role in providing a good visual, biologically effective and energy efficient lighting of indoor spaces. Generally, daylight is the light source preferred by humans. Daylight is the major source of regenerative energy for reducing lighting energy consumption. Electric lighting accounts for approximately 15% of the total electrical power consumption and 5% of greenhouse gas worldwide. In nonresidential construction, daylighting – based on distinct evaluation procedures and integrated into diverse energy saving ordinances – has meanwhile become an energy-quantifiable and plannable light source that can be directly offset against the energy requirements for electrical lighting.
 

The overall objective of the Task is to foster the integration of daylight and electric lighting solutions to the benefits of higher user satisfaction and at the same time energy savings. The Brochure gives an overview on the Task activities.
