Star Rating
Energy Efficiency Requirements

Most of us are familiar with energy rating labels for electrical and gas appliances like refrigerators & freezers, washing machines, dishwashers etc. The star rating helps us to compare the running costs and energy efficiency levels of different models of those appliances. By selecting the most energy efficient appliance energy use and costs can be reduced.

Since 2003 the Building Code of Australia (BCA) requires Energy Efficiency Measurements for all new residential buildings in WA. Different software packages are used for star rating homes and buildings.

Energy efficiency measurements are also required for Class 2 to 9 buildings.

The BCA provides a two process pathways that can be followed for a Building Solution (Class 1) to meet the Performance Requirement. These are described as:

• Acceptable Construction (Deemed-to-Satisfy Provisions).
• Alternative Solutions (this may not be accepted in future)
