In 2003, the Australian Building Codes Board introduced a change in modern home and building construction in the continent: the House Energy Rating. It’s the indexing system of building thermal performance and home energy efficiency. Since then, Australian states and territories have branched off and made their own path in ensuring the global energy standard to their homes.
Though the rating system has radically changed Australian architectural landscape, many people are still in the dark on how it works. To fully understand the mechanics of the energy efficiency rating, take note of the differences among state government directives.
Assessing the Living Standards
One important factor in energy assessment is the climatic conditions in different parts of the country. Each region has its own set of climatic patterns. The city of Darwin, for example, is much closer to the equator so residents experience a subtropical climate. Melbourne city, on the other hand, live through more varied changes in temperature. These variations in local climate throughout the country call for a more specific approach.
To address the particular needs of their region, state governments have initiated different schemes that bolster their local building regulations. In Western Australia, the local government has introduced further energy regulatory requirements. They have included a standard set for energy performance of hot water systems and provisions for alternative water supplies.
Reaching for the stars
Before the introduction of the House Energy Rating regulation, not more than one percent of Australian houses reached even a 5-star rating. Now, building contractors and construction firms are building houses with a rating of six and above. More stars means less artificial means for cooling and heating to stay comfortable. It also means lower utility costs for the homeowners.
In Victoria, for example, it is mandatory that all residential buildings and infrastructures have at least a 6-star rating. Assessors can either rate the building before or after the construction is done. They take into account the home layout; orientation of the windows; roof, walls, window, and floor construction, and other considerations.
Indeed, the House Energy Rating has changed many lives. Australian home living standards have vastly improved and became the global benchmark. Australian residents can now live in peace in the comforts of their 6-star home.
