Two ARTD evaluations of energy efficiency programs have been published by the NSW Office of Environment and Heritage (OEH). The first is an overall evaluation of the NSW Energy Efficiency programs to June 2012. ARTD worked in partnership with OEH to assess the effectiveness of the programs under the former Energy Efficiency Strategy, with a focus on the efforts made to produce reliable measures of energy savings.
The second is an interim evaluation of Home Power Savings Program (HPSP), one of the programs established under the former Energy Efficiency Strategy. The HPSP had the aim of helping 200,000 low-income households reduce their power usage and save on energy bills between July 2010 and June 2014, by providing participants with a home assessment, an action plan and a kit of energy efficient items. Our interim evaluation, which included an analysis of participant data, a detailed local case study and a cost-effectiveness assessment, informed further development of the program. We are currently working with OEH on an evaluation of the behaviour change component of program, introduced in June 2013 to test behaviour change intervention methods that could support better outcomes for participants.
