Some Australian home builders are already striving to move beyond minimum requirements by incorporating energy efficient designs and technology innovations into new homes that are healthier, more comfortable and more affordable to run. However, these builders lack scale and face significant barriers. Consumers are unclear of their choices – and are baffled by all the terminology. Home builders are locked into business models and supply chains that limit innovation. And financiers don’t value sustainable homes.
This roadmap offers a golden opportunity to proactively address these challenges and achieve a smooth regulatory transition through complementary market-based support. Research shows that this can create a win-win outcome for builders, consumers, the economy and the environment.

In response to feedback, high-income households can reduce their energy use to a larger degree than low-income households (17% vs 3% reduction). This and other insights were gained by two rapid reviews into research, both Australian and International, on digital services and...Read more
A rapid review on green-rated office buildings, and their operational energy use, found that the conclusions of six studies ranged from the certified buildings performing worse, similarly or much better than the non-certified buildings in terms of energy usage intensity. Two...Read more
Sustainability assessment tools aim to promote high sustainability outcomes in residential buildings, ensuring less consumption of water, energy and less emission of greenhouse gases. However, existing literature often presents variations between the estimated outcomes from the assessment tools and actual outcomes after building occupation.
Building energy codes lay out the minimum requirements for the envelope (insulation, windows and air sealing), mechanical equipment and lighting of a building (residential and commercial) in terms of energy efficiency/conservation for new construction or major renovations.
