The Deemed Energy Savings Method provides robust and easy to use equations and factors to calculate energy savings from the installation of common equipment. It uses the following methods from the Energy Savings Scheme Rule:
- Commercial Lighting Energy Savings Formula
- Default Savings Factors
- High Efficiency Motor Energy Savings Formula
- Power Factor Correction Energy Savings Formula
The Deemed Energy Savings Method is used for the installation of common end-user equipment, such as refrigerators, lighting and certain types of high efficiency electric motors. A program of installing multiple end-user equipment of the same type is considered a single energy savings project (or Recognised Energy Savings Activity as defined in the legislation).
The Deemed Energy Savings Method measures the lifetime or deemed savings of an energy savings project upfront, before the actual savings occurs. Energy savings certificates can be claimed at the time of installation for the deemed lifetime of the energy savings project.
This allows lifetime benefits of the energy savings project to be capitalised at the time of implementation and may reduce the financial burden of implementing the energy savings measures.
Commercial Lighting Energy Savings Formula
This formula can be used for commercial lighting upgrade projects that achieve energy savings.
It cannot be used in conjunction with the Project Impact Assessment Method or the Metered Baseline Method, where this would involve double counting of the energy saving.

Default Savings Factors
The Default Savings Factors Method can be used for:
- replacement of halogen downlights with energy efficient alternatives (but not the installation of compact fluorescent light globes)
- the sale or purchase of energy efficient clothes washers, dishwashers, fridges or freezers
- the retirement of old spare fridges and freezers.

High Efficiency Motor Energy Savings Formula
This formula is used for projects that involve energy savings attributable to the sale or installation of one or more high-efficiency motors.

Power Factor Correction Energy Savings Formula
This formula is used for projects that deliver energy savings attributable to the reduced losses from the installation of Power Factor Correction equipment.
