"Climate change and energy costs mean we need to rethink how we design and
build our homes. The updated National Construction Code has lifted the required
energy performance of new housing from 6 stars to 7 stars (10 stars being the
best). Windows are an obvious focus for improving the energy efficiency of
On hot days, most of the heat that gets into our homes is through the windows.
On cold days, windows account for almost half the heat loss. High-performance
insulating windows have been installed in Australian homes at a fraction of the
rates for New Zealand, the United States and the United Kingdom.
In our newly published report, we found the local window industry can produce
the high-performance windows we need for thermally efficient homes. These homes
will cost less to heat and cool, with lower greenhouse gas emissions.
But the industry is complex, with several obstacles to greater uptake of these
windows. We identified a range of government policies and industry actions that
could help drive change."
