2016 Residential Lighting Survey and Audit
A recent E3 lighting survey and audit of households has revealed lighting energy consumption has reduced 40% from 2010 to 2016. However, a wide range in overall household lighting efficacy indicates scope for further improvement.
The 2016 residential lighting survey and audit of 180 households in Queensland, New South Wales and Victoria was conducted to better understand installed lighting stock and trends, attitudes to efficient lighting and user behaviour. E3 conducted a similar project in late 2010 and early 2011. As the first survey occurred over a year after the 2009 phase-out of incandescent lamps, it’s likely that the full extent of change from efforts to improve household lighting efficiency may be even greater than 40%.
Data was collected through a lighting audit (counting the number of light bulbs, type and wattage), and a self-completion survey.
Key results include:
- A 40% reduction in energy consumption from 2010 to 2016;
- A reduction in the use of low efficacy technologies (incandescent and halogen), which now represent 45% of the stock of installed lamps;
- A significant proportion (60%) of residential lighting energy consumption estimated to come from these incandescent and halogen lamps;
- A considerable improvement in task and directional lighting efficacy due to a reduction in halogen downlights and an increase in LED share; and
- A significant variation in the overall household lighting efficacy ranging from 10 to 65 lumens per Watt, suggesting that the transition to efficient lighting is not uniform.
