Star Energy Rating Appliances for Energy Efficient Homes
The Energy Rating Label for electrical home appliances was introduced in NSW and Victoria in 1986. Nowadays it is mandatory in all of the Australians states and territories to carry the energy label on electrical appliances. In Australia, this rating system has positive economic and environmental significance.
The main purpose of the Star energy rating is to improve the energy efficiency of appliances in order to reduce greenhouse gas emissions and national energy demand. Ultimately, the energy efficient appliances help their owners to save money on the energy bill.
What is the Star Energy Rating for Appliances?
Depending on the size and energy consumption of an electrical appliance, it is labelled on a scale of 0 to 10 stars. According to the scale, the greater the number of stars the higher the efficiency. The rating enables a consumer to compare two domestic appliances and chose the more energy efficient one. It also provides insight to the manufacturer for further improvements. Eventually, the least energy efficient products are removed from the market.
All the appliances are rated under Australian Standards, which define test procedures for measuring energy consumption and minimum energy performance criteria. The appliances that are bound to Star energy ratings are:
- Washing machines
- Domestic televisions
- Clothes dryers
- Single phase Air-conditioners
All these appliances must have a label defining their energy rating, which denotes their energy efficiency.
There are two types of labels – Comparing and Endorsement. The first label provides the information that you need to compare the energy efficiency of a particular product and the second label acts as a “Seal of Approval” for a potential purchase. The comparing label includes three subdivisions. One of them is mandatory and the rest are voluntary. They are as follows-
- Energy Rating Label (Mandatory)
- Swimming Pool Pumps Label, &
- Zoned Energy Rating Label
Why is this Rating Important?
According to the report of the second baseline study on residential energy usage, over the period of 1990 to 2020, overall household energy consumption has increased by 56%. With the support of the Australian Government, the study was conducted by energy planning and policy consultants Energy Efficient Strategies Pty Ltd (EES).
To receive a building permit, all the residential and commercial buildings in Australia must have a specific energy rating; similar to the appliances, the building rating is also on the scale of 0 to 10. Better energy star rating appliances improve the energy efficiency of the building shell. Installing home appliances that have a higher energy rating helps to get a higher rating for the building.
The Energy Rating Label on home appliances provides consumers or home owners with the following information:
- A comparative energy rating assessment of the model’s energy efficiency.
- The ‘comparative energy consumption’ (kilowatt hours/year) provides an estimation of the annual energy usage of the appliances. It’s based on the tested energy consumption and information about the common use of the appliance in the household.
When an appliance earns the optimum energy star rating, it tends to become a bit pricey. Though in the long run, the proper handling and management of energy efficient appliances can make a big difference.

These two vital pieces of information, along with efficient energy rating assessors in Victoria and NSW, provide a house energy rating for buildings; this rating is mandatory to achieve building permit. The energy rating consultants can also advise on how to design and model a better energy efficient structure from scratch, purchasing appliances with the best Star energy rating.
