Scope

The potential for energy savings in lighting is very large and can be further increased by integrating electric lighting, daylighting and HVAC systems. The character of lighting used in buildings is changing dramatically in parallel with these efficiency-related changes. The implementation of new light sources, integrated and ‘smart' controls and innovative luminaires provides the opportunity for much greater variation in the spatial distribution, spectral content and temporal control of various light sources. These flexible and responsive systems are seen as having critical value to the next generation of lighting solutions in buildings.

As lighting moves into this more dynamic regime, it is critical that the impact on performance of the system components, the end user, and associated integrated building systems are well understood, documented and predicted.

The components that affect the total lighting energy use are and, thus, the scope of Annex 45 is:

  • The lighting equipment used (lamps, ballasts, luminaires, sensors, etc)
  • The lighting performance targets and design of lighting
  • The control and integration of lighting.
