Stiebel Eltron Supports Lifting Energy Performance Standards For New Homes

It has been over a decade since Australia meaningfully increased the minimum energy efficiency requirements for new homes in the National Construction Code. In that time, we have fallen further behind international standards while the need to reduce emissions has grown even more urgent.

As a result, new home buyers are now more exposed to the impacts of the current energy crisis and paying more than they should to keep their homes warm in winter and cool in summer.

We call on Building Ministers to adopt proposed new energy performance requirements for residential buildings in the National Construction Code 2022 with a 12-month transition period to ensure time for industry training and education.

The proposed energy provisions follow a collaborative 3-year process led by the Australian Building Codes Board (ABCB), consistent with the Trajectory for Low Energy Buildings agreed by all Commonwealth, state and territory energy Ministers in 2019. The ABCB’s proposals for new homes include raising the minimum thermal performance standard from 6 to 7 stars (NatHERS equivalent) and the introduction of a ‘whole -of-home’ energy budget for fixed appliances (heating and cooling, hot water, lighting, and pool and spa pumps).

Our organisation recognises and strongly supports the intent of these proposed reforms - as Ministers noted after their meeting in March 2022, these improvements are part of a broader national effort to manage cost of living pressures for households, while making a strong positive contribution to decarbonising our economy.

Lifting energy performance standards will:

Cut energy bills. The Australian Building Codes Board finds that households will be up to $576 a year better compared to business as usual.˙ Savings on energy bills will be larger than the home loan cost of upfront improvements.

Cut emissions by up to 15 million tonnes to 2030, and 78 million tonnes to 2050 nationally.

Make homes healthier and more resilient. Houses that are too cold contribute to 6% of deaths in Australia - double the rate in Sweden.˘ There were 36,000 deaths in Australia associated with the heat between 2006 and 2017, with heat waves predicted to worsen.

Make energy more affordable for all by managing energy demand and reducing the cost of grid upgrades by up to $12.6 billion by 2050. Efficiency is a key measure to reduce the impact of volatile wholesale prices on households.

Reduce poverty and inequality as people living in all new social housing and private rental will benefit from cheaper energy bills and better health outcomes.

All Australian homes should be safe, healthy, comfortable and affordable. Now is the time to lift energy performance standards for new homes.
