Practice Energy Efficient Techniques

Layering

Many environments including homes now use layering; low LUX levels over wide areas for general access and higher LUX levels in precise areas for work activities, safety and highlighting of features, artworks, etc.
The use of layering with several switched and dimmable circuits in a room can achieve a high degree of energy efficiency along with greater comfort and ambience.

Daylighting

Optimise the use of natural light within a building, north facing windows provide light throughout the day. Efficiency can be improved by planning banks of lighting, so that only dark areas are artificially lit at certain times of the day.

Task Lighting and Spot Lighting

The recommended LUX levels in AS/NZS1680 often only apply to precise areas. Use of task lighting such as desk and floor lamps as well as spot lighting will be most efficient for these work areas.

Automatic Controls

Areas infrequently used can have sensors or timers installed to switch lights on and off.
