This page lists the different methods used to calculate energy savings for eligible activities under the Energy Savings Scheme
The Energy Savings Scheme allows energy savings to be calculated using three methods. The methods also have 'sub-methods' designed for the particular activities. The method you use depends on the activity you will implement.
This method calculates energy savings across large groups of energy customers using statistical analysis.
This method is used to calculate energy savings from the installation of high efficiency commercial refrigeration and air conditioning systems and high efficiency motors.
This method is used to calculate energy savings from eligible commercial lighting upgrades, where lighting standards have been met.
This method is used to calculate energy savings from a range of common household and small business energy saving upgrades.
These methods are best suited to 'whole of site' energy savings. One of three calculation methods can be used, depending on the site.
This method uses NABERS ratings to calculate annual energy savings from office buildings, shopping centres and hotels.
This method calculates energy savings from the reduced electrical losses resulting from the installation of Power Factor Correction equipment.
This method calculates 'equipment level' energy savings where the overall reduction in electricity use is a small proportion of total site use. This method is closed to new applications for accreditation.
This method utilises internationally recognised measurement and verification principals to verify energy savings. It allows 'equipment level' energy savings to be deemed for up to ten years, using persistence and confidence factors to discount initial certificate creation.
This method can be used to calculate energy savings from eligible upgrades of lighting for roads and public spaces or traffic signals.
This method is used to calculate the energy savings resulting from removal of old, energy intensive appliances.
This method is used to calculate the energy savings resulting from bulk sales of energy efficient appliances and whitegoods.
Previous versions of the guidance documents for each method are available on this page.
