This case study describes how an ACP provided a lighting and control system upgrade package for a Ladies’ College in Sydney. All incumbent lighting equipment was upgraded to state-of-the-art LED technology and several buildings were also upgraded with smart lighting automation to minimise energy wastage.
Energy Savings Scheme (ESS) role and site type
An ACP engaged with a Ladies' College (the original energy saver) to identify and realise energy savings through a lighting upgrade. The ACP then used the energy savings to create Energy Savings Certificates (ESCs) through their accreditation, using the Commercial Lighting Energy Savings Formula method, under the NSW Energy Savings Scheme.
Significant energy and cost savings were identified by the ACP, who provided an electricity efficiency upgrade package, identifying all existing T8 fluorescent fixtures and halogen lamps as a major opportunity for an upgrade to LED fixtures.
A small trial of the LED fixtures at the school was conducted. Overwhelmingly positive results were achieved in this trial and a much larger roll out of the LED technology was completed.
Over 1500 T8 fluorescent tubes and over 500 halogens were replaced with LEDs over two separate roll out phases during 2011 with additional upgrades being completed in 2012.
The ACP used the Commercial Lighting Energy Savings Formula to calculate the energy savings from this project. The determination of actual energy and cost savings followed current best practice, as defined by the International Performance Measurement & Verification Protocol (IPMVP) framework. This calculation takes into account logged hours of use of each of the different areas upgraded, seasonal variations in temperature and output as well as the effects of time of use electricity tariffs and all other electricity network and peak demand charges.
Energy savings from this project resulted in the creation of 2,679 certificates during 2011.
