"For years, builders and developers have treated “sustainable” homes as someone
else’s problem. Solar panels, batteries, double-glazed windows, correct
insulation, good ventilation and better materials have been thought to be too
expensive, too niche and too unprofitable to include in new homes, so they were
left out.

The result is predictable. Homeowners move in, receive high energy bills, feel
uncomfortable temperatures, and eventually pay to retrofit the same features
the builder skipped. But that often costs much more than it would have to
include them during construction.

Homeowners get a poor outcome, because retrofitting an existing home is harder
and more costly than designing it well at the start. This approach to building
fills Australia with houses that underperform on energy efficiency, comfort and
running costs for decades.

Our research reveals developers could actually make a bigger profit than they
do now from new home builds that include more sustainability features."
