Why be energy efficient?
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:
- Energy Efficient Lighting Technology Report 2014 (Opens in a new window)
This technology report outlines energy saving solutions to increase the efficiency of common types of lighting. Annual energy savings, capital costs and payback periods have been modelled and examples provided.
The report will help users understand the potential for energy efficient lighting at their site and provides guidance for making the most cost-effective energy efficient technology upgrades. Generic technical specifications are provided which will allow users to confidently approach lighting suppliers and contractors.
- Energy Efficient Lighting Technology Report - technical details 2014 (Opens in a new window)
- NSW Office of Environment & Heritage
- PDF 1.0 MB
This report is for suppliers, installers, plant operators, site engineers, and facilities seeking more detailed technical information about lighting upgrade options. The document contains detailed information for each lighting option including a technical specification, to allow for correct requests to lighting suppliers.
The technical specifications are designed to be used in conjunction with the main document – Energy Efficient Lighting Technology Report.
- Calculight - the energy efficient lighting upgrade calculator 2014
- NSW Office of Environment & Heritage
This tool can help to identify appropriate upgrade options and compare them by cost, energy savings and payback period. Once the most cost-effective solution is identified, generic technical specifications can be used to confidently approach lighting suppliers and contractors.
- Energy Saver Training: Lighting 2014
- NSW Department of Envrionment & Heritage
Lighting systems can be responsible for up to 50 per cent of a business’s energy use. The Energy Saver program’s training is designed to help understand current lighting technologies, investigate best-practice lighting solutions and apply them to reduce site’s energy use and cost.
