Commercial Lighting

This page provides information about the Commercial Lighting Energy Savings Formula
(Commercial Lighting)

About this method

The Commercial Lighting Energy Savings Formula (Commercial Lighting) is used to calculate energy savings from upgrades of existing lighting, including:

  • general purpose building lighting
  • lighting for roads and public spaces, or
  • traffic signals.

It requires that lighting upgrades meet the requirements of lighting standards, and that lighting upgrades are performed by people with appropriate training.

Using the Commercial Lighting method

Method Guide

The requirements for using this method are presented in the Method Guide below.

Method Guide: Commercial Lighting1.25MB PDF FileV3.2 April 2016
The Method Guide provides the information required to conduct activities using this method of the ESS Rule. This version was published following amendments to the ESS Rule in April 2016.

Template Nomination Form

The Energy Savings Scheme Rule of 2009 allows an original energy saver to nominate an Accredited Certificate Provider as the energy saver in relation to the implementation of a recognised energy saving activity at a particular site. Such a nomination must be in the form and manner approved by the Scheme Administrator. Templates for nomination forms can be found on the Templates page.

Fact Sheet

The ESS Commercial Lighting Fact Sheet must be provided to the Purchaser at the start of the lighting upgrade. The purpose of the Fact Sheet is to provide the Purchaser with:

  • an overview of the ESS
  • key details about commercial lighting activities
  • contact details for relevant authorities

The ESS Commercial Lighting Fact Sheet provides the purchaser with information about the ESS and the Commercial Lighting method. This document replaces the Building Lighting Information Sheet.

Post Implementation Declaration

The ESS Commercial Lighting Post Implementation Declaration must be completed upon completion of the lighting upgrade. It confirms that the upgrade meets lighting quality requirements and that the purchaser is satisfied with the upgrade. The Post Implementation Declaration must be completed for each implementation and a copy of the completed form must be kept as a record for each implementation.

Evidence Manual

To make it easier to collect and retain the right information to support energy savings, we have developed the Evidence Manual. It includes information about:

  • the evidence required to support each parameter of a lighting upgrade, and 
  • how to complete the evidence pack.

Evidence Manual: Commercial Lighting1.57MB PDF FileV2.2 April 2016.
The Evidence Manual details the information required to support ESC creation. This version was published following amendments to the ESS Rule in April 2016.

Evidence Pack

The Evidence Pack is the core record to evidence energy savings from commercial lighting activities. On each occasion a lighting upgrade is performed (at every site) a record of the activity must be made using the associated Evidence Pack.

Evidence Pack: Commercial Lighting170.02KB Excel SpreadsheetV2.2 April 2016. The Evidence Pack is used to record information about each activity. This version was published following amendments to the ESS Rule in April 2016.

Please note:

  • Accredited Certificate Providers are required to use this evidence pack for all upgrades implemented on or after 1 July 2014.
  • Accredited Certificate Providers are able to adjust the format of the evidence pack to suit their own business processes.
  • The 'Multiple Implementation Cover Sheet' has been replaced by the ESC Registration Form.

Alternative Evidence:

Proposals to collect evidence not currently included in the Evidence Manual will be considered on a quarterly basis. If you wish to propose alternative evidence, please email the ESS Compliance Mailbox.

If accepted, the evidence will be published in the next regular update to the guide, at which point you can consider the evidence approved for use.

Calculating Energy Savings

A ready-to-use calculation tool is provided (below). This Excel calculation tool helps you to use the Commercial Lighting Formula. This tool can be used for building lighting upgrades and lighting for roads and public spaces.

Current ESS Rule

Commercial Lighting Calculation Tool v6.1547.64KB Excel SpreadsheetVersion 6.1 April 2016
This version of the Tool can be used to calculate energy savings using the current ESS Rule, which commenced on 15 April 2016.

The Commercial Lighting Calculation Tool is provided to assist with calculations of energy savings. It is not compatible with all systems and is provided on an unsupported basis. As such, IPART will not be able to assist with queries or issues encountered when using the tool.

Please note: As a result of a December 2014 Microsoft Office security update, some users may experience errors that prevent them from using the controls on the Commercial Lighting Calculation Tool (CLCT).  If you are receiving errors please follow the instructions below to install two updates necessary for the CLCT to function.

1. Install the relevant security update for your version of Microsoft Office from the link below.

  1. Go to File-->Options-->Trust Center-->Trust Center Settings-->Click on ActiveX Settings on the left, then select ‘Disable all controls without notification.’
  2. Click ok.
  3. Save and Rename the calculation tool..
  4. Go to File-->Options-->Trust Center-->Trust Center Settings-->Click on ActiveX Settings on the left, then select ‘Prompt me before enabling all controls with minimal restrictions’
  5. Click ok.
  6. Load the renamed calculation tool.

We recommend you consult your IT support provider before installing these updates.

Commercial Lighting Calculation Tool - DA Version

We no longer provide a version of the Commercial Lighting Calculation Tool in relation to equation 8 of the ESS Rule.  Please contact us if you intend to use equation 8 to calculate the Baseline Energy Consumption (eg, some projects involving development approval).

Additional Guidance

Emerging Lighting Technologies

More information is available on the lighting technology page

Equipment that is classified in the ESS Rule as an emerging lighting technology needs to be accepted for use in the scheme.
