Increased use of natural light saves energy


In an effort to reduce its electricity consumption, ASSA ABLOY Australia has replaced some of the roof at its Melbourne facility with translucent panels and installed daylight sensors so that the lights can be turned off automatically when there is sufficient natural light.

As the buildings at the Melbourne site are now quite old, most of the translucent panels had become dirty and were not allowing a great deal of sunlight through. As a result, it was decided to repair, clean or replace these existing panels as required, in addition to installing additional translucent panels elsewhere throughout the facility.

To maximize energy savings, sensors were also installed to ensure that the artificial lights only turn on when there is not enough natural light.

This and other projects have reduced electricity consumption at the Melbourne facility by approximately 5 percent, while maintaining safe light levels, for an annual saving of around AUD 35,000 (about 27,400 EUR).

ASSA ABLOY Australia has also tested the use of motion sensors for lights in some parts of the Melbourne factory, which will one day ensure that – even when there is insufficient natural light – the artificial lights will only turn on if there is someone in the area.
