Residential buildings represent 12% of Australia’s emissions and make up 25% of electricity demand. The existing building stock is energy and carbon intensive and occupants suffer from high energy bills, poor health and comfort, and are vulnerable to energy price spikes. A recent study by Sustainability Victoria has also demonstrated that renovating homes had major impacts on the health and financial stability of vulnerable households. Accelerated and increased efforts in energy efficiency and electrification will reduce energy consumption and protect households from climate impacts and energy prices, particularly those in social housing and low–income households.
