Communities and Local Government has yet to install any voltage optimisers in its main buildings. A number of feasibility studies have been undertaken but installation has been delayed until our buildings are at maximum occupancy. Only then will we have a full understanding of the appropriateness and return on investment of this type of technology relative to our specific buildings.

The Department is strongly committed to reducing its energy demand and related carbon emissions, and is installing a range of energy efficient technologies in its buildings including:

Free cooling circulation for kitchen air supply

Lower energy lighting with high frequency ballasts, and LEDs

Boiler optimisers

High efficiency chillers with heat recovery.

In 2009, the Department reported a 33 per cent. reduction in carbon emissions from its central offices and achieved the Carbon Trust Standard, demonstrating a sustained commitment to carbon management, and a proven track record of year-on-year energy reduction.
