A lighting audit will assess what the tenancy currently has in place. It will require a map of the area, showing the type and location of each light in the room. A calibrated light meter should be used to measure and record illumination levels at key points in each room. The audit will likely document lighting area dimensions, fixture quantities, locations and mounting heights, lamp types, quantities and wattage.

Whether lighting audits are done in-house or lighting specialists are used to assess your needs, energy managers will need to speak to staff about how the areas are used before making final recommendations.
The audit results will help identify solutions including reducing light levels (de-lamping) and upgrade opportunities. A lighting or energy efficiency professional can make recommendations on an appropriate lighting system design, including sensors for less frequently used areas and more advanced control options. They should be able to estimate financial and greenhouse gas savings and make recommendations for financing options.
The NSW Office of Environment and Heritage’s Lighting Technology Report is intended to help organisations confidently approach lighting suppliers and contractors and help to build a business case by modelling annual energy savings, capital costs and payback periods and providing examples.
The calculite tool accompanying the Lighting Technology Report is an online calculator that suggests upgrades, compares options, and provides generic technical specifications to take to suppliers.
