Our Work: Low income energy efficiency "Our Green Home"

About "Our Green Home"

Typically, 10-20% of energy in any household is wasted.

Low-income households spend on average $1,500 on electricity each year. They are more likely to have lower electricity bills than average and higher income households, but not significantly so. That means electricity bills for low income households represent a much higher proportion of total income.

SBA led a Project Team of SBA Members (Object Consulting, Connection Research, KPMG, McCullough Robertson), and partnered with the community organization Apex Australia to seek Australian Government Low Income Energy Efficiency Program (LIEEP) funding.

Role and expected outcomes

The main objective of this Federal Government co-funded Project is to collect extensive data for analysis of energy consumption in low-income households, overcoming the barrier of information asymmetry. Our Green Home bypasses the perceived limitations of the NEM and provides a unique online monitoring platform capturing consumption data every 5 seconds. The program is due to report in December 2015.

Our Green Home has invited householders from across metropolitan, regional and rural communities to take part in the project. More than 600 households are currently in the program and have either had energy monitors installed in their homes or been asked to take part in surveys. Participants are reporting that access to the energy information has helped them to take charge of their electricity bills by being more aware of what appliances are using electricity and when. One participant reported he had saved $1,000 for his two person household by taking part in Our Green Home. (Northern District Times, 18 March 2015)

Householders with energy monitors installed gain online access to their real-time energy consumption, associated costs and comparison with other households, with immediate visibility of the effects of turning on and off appliances. The platform enables householders to track their real time energy consumption and calculate cost savings.

Final Milestone Report

    The data collected from the electricity retailers shows an average quarterly electricity consumption per participating household (all participants across all quarters) of 1307 kWh. This equates to 5228 kWh per year, a figure around 10% lower than the best estimate from the Australian Energy Regulator of an average annual consumption of 5817 kWh. At an average tariff of 25 cents / kWh, the average annual household electricity bill in Australia is $1454.25 ($363.56 per quarter). A 5.0% savings on this amount represents an annual figure of $72.71, which is the figure used in this report and in the cost effectiveness and cost benefit analyses. 5817 kWh per year for the average Australian households means a total retail electricity bill of over $1 billion ($1,118 million) across all 7.7 million households in the country. A reduction of 5.0% across all households would mean a savings of around $56 million. For stand alone houses only (76.3% of housing stock), this equates to an annual Australia‚Äźwide savings of $42 million.
