The Scorecard assessment looks at the main drivers of high energy bills: the building itself and fixed features like water heating and space heating. The resulting star rating is independent of household habits and can be used as a method of direct comparison between houses, or before and after renovation.
The star rating is a government derived rating and is roughly equivalent to the energy rating system used on new homes (currently 6 stars for Victoria).
Scorecard assessor will look at:
• Building's shell: wall, floor and ceiling materials, insulation, windows and eaves, gaps
• Fixed features: heating and cooling systems, hot water systems, lighting, curtains and external blinds, solar panels, pools and outdoor spas.
• Non-fixed appliances like fridges and washing machines are not included.
The home energy assessment assesses the following:
• Construction materials
• Heating system
• Cooling system
• Hot water system
• Renewable energy sources
