Why be energy efficient?

High-efficiency LED.

High-efficiency LED fitting (EEX).

Lighting can account for up to 40% of energy costs in commercial buildings and up to 7% of industrial energy use.1 There are many low-cost and no-cost measures that can be implemented to reduce these costs without adversely affecting working conditions.

Lighting energy savings of 75–90% can be achieved using daylighting and task lighting strategies and using the most efficient equipment.2 It is also a very visible way to demonstrate to staff that energy efficiency is a business priority and to encourage them to take an active role in reducing energy costs.


A good energy efficient lighting strategy relies on an integrated approach that includes the following elements:

  • Reduce demand for artificial lighting

    There are several highly effective strategies to maximise the amount of natural lighting, referred to as ‘daylighting’ a building. Techniques...
  • Optimise the use of existing lighting systems

    Many lighting efficiency opportunities can be easily implemented with little or no capital or the need to redesign a lighting...
  • Upgrade lighting systems

    There are excellent opportunities for energy saving whenever upgrades or refurbishments are planned.[1. Sustainability Victoria (2009) Energy Efficiency Best Practice...
