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.

Practitioners are using a wide variety of different workflows, methods and tools in the planning of integrated solutions for daylighting, electric lighting and lighting controls. Lighting design projects cover a huge variety of applications with different requirements as well as project types and sizes. Within the Subtask C “Design Support for Practitioners – Tools, Standards, Guidelines” of the IEA SHC Task 61 / EBC Annex 77 “Integrated Solutions for Daylighting and Electric Lighting: From Component to User Centered System Efficiency” currently applied workflows in practical applications have been reviewed.

Lighting accounts for approximately 15% of the global electric energy consumption and 5% of greenhouse gas. Projections by the IEA show that if governments only rely on current policies, global electricity use for lighting will grow from around 2,900 TWh to around 4,250 TWh by 2030. Due to the world’s growing population and the increasing demand for electrically driven services in emerging economies, the increase will occur despite constant improvements in the energy efficiency of lighting systems.
