Net Zero Homes

In Australia, it has never been easier to live in a net-zero home. Also known as “carbon neutral homes,” pure eco-living is no longer reserved for ‘tree huggers’ that live completely off of the grid, as there are dozens of developers building sustainable living spaces in urban and suburban across the country. 

Below, we will explore a heaping portion of Australia’s most exciting net-zero homes before looking into the components of carbon-neutral living and answering frequently asked questions about today’s most common terminology.

Things to Consider when Buying a Net Zero Home

When buying a net-zero home in Australia, there are a handful of things that need to be considered in finding the perfect living space. While you’ll obviously have to think about all of the ordinary property search variables (i.e. number of bedrooms, bathrooms, etc), net-zero living brings a few unique elements in the decision making.

Net-zero homes vs. carbon-neutral communities 

If you’d like to live a carbon-neutral lifestyle, there are essentially two ways to achieve it: 1. On your own or 2. Within a community. In this article, we featured both net-zero home builders and community developers to help a wide range of people achieve a green lifestyle. 

With an existing plot of land already purchased, Aussies anywhere in the country can now find an eco-home builder to help lower their energy use and expenses. In the dense and growing cities Down Under, however, the country’s newest Green Star communities are a great way to live comfortably without the carbon guilt. 

Even more so, by pulling together shared resources, Australia’s net-zero communities are much more likely to be net-positive, while standalone homes are generally designed to consume and use the same amount of energy. Within a Green Star Community, rental options are also usually available.

Amenities 

Inside and out, amenities are also extremely important in finding the right net-zero home. While independently operated houses may have you sacrificing certain luxuries to achieve net-zero, large green communities are more likely to have bonus amenities like nearby parks, event spaces, and connections with local transportation. 

On a home, net carbon living is almost always paired with PV solar. WIth a battery-backed system, residents can gain even more grid independence, and water heating systems can also utilize solar hot water or heat pump technology to stay green across the board. Beyond carbon itself, many of today’s net-zero homes also have water-saving features and other sustainably minded extras. 

While fortifying for the future, Australians should also keep in mind their electricity use for years to come. If an electric vehicle is a real possibility, homeowners will want to ensure that their net-zero home will have enough electricity to provide an efficient charge. Thankfully, in urban developments, more and more EV chargers are being utilized to support widespread electrification. 

Frequently Asked Questions about Net Zero Homes 

Finally, if you’re still scratching your head about how net-zero homes really work, below, we’ll take a look at some answers to the most frequently asked questions on the subject. 

Are net-zero homes worth it?

Yes, although they may be a bit more expensive than an ordinary house, net-zero homes are 100% worth it both for your budget and the planet. With efforts to reduce carbon emissions and increase sustainability, net-zero homes minimize energy use and create a better future for the next generation. 

In terms of everyday living, net-zero homes are designed to save owners money on monthly and annual expenses. From lower water bills to virtually extinct electricity charges, net-zero homes are an investment in the future in more ways than one. 

What is the difference between a passive house and Net Zero?

While the terms are very similar and often used together, there are a few key differences between a passive house and a net-zero home. A passive house is designed to use as little energy as possible, to be completely independent, and run on its own systems. To achieve this, a passive home utilizes smart building materials and design, insulation, and other sustainable practices. 

On the other hand, a net-zero home is any building that produces as much energy as it uses. Passive homes can often achieve net-zero, but net-zero homes can also be located within a large community or collective energy grid. 

What are the components of a net-zero energy house?

Except when they are being built by the same developer side-by-side, there is no “standard” net-zero energy house design or list of components. However, there are a few main principles that most net-zero energy homes and communities share. They are as follows:

  • Alternative energy source – Like PV solar, wind, or heat pumps
  • Passive building design – constructed to keep interior temperatures stable
  • Energy-efficiency efforts – such as a high-performance building envelop and smart appliances that reduce overall consumption 

How does a building become net-zero?

A building officially becomes net-zero when it consumes the same amount of energy that it produces. While “net-zero” is most often used to describe energy neutrality, buildings can also become “net-zero” for water consumption with rainwater harvesting and other conservation techniques. 

If you’re attempting to retrofit your building to become net carbon zero, conscious efforts should be made to increase energy efficiency wherever possible. Once this has been completed, home and owner builders should then seek out on-site or virtual renewable energy production to achieve an overall net-zero rating. 

What is a Green Star rating?

Green Stars are an internationally-recognized Australian sustainability rating and certification system pioneered by the Green Building Council of Australia. There are a few different kinds of Green Star ratings including those eligible for single-family homes, shared occupancy buildings, and communities alike.

Eligible buildings will receive a 4, 5, or 6 Green Star rating depending on a wide set of criteria. Beyond the efficient use of energy, water, and waste systems, highly rated Green Star Homes and Communities are evaluated on the buildings’ and developments’ overall environmental and social impact for years to come. 

What is a NABERS rating?

Separate from Green Star ratings, the National Australian Built Environment Rating System (or NABERS) is also used to help sustainably develop large shared spaces. Primarily, NABERS ratings are used as a sort of “green energy certificate” for developments like shopping centers, office buildings, and other large commercial spaces.

Like the Green Star system, NABERS ratings are given on a 6 point scale and account for things like energy, water, waste, and interior spaces. Awarded by independent assessors and audited by local governments, NABERS ratings can also be trusted alongside net-zero and Green Star certifications for sustainable living.   

Conclusion

Ultimately, over the past 20 years, Australians have made a large amount of impressive efforts to lead a more suitable future of living. With so many new and existing Green Star homes and communities on the way, it has never been easier for Austiralsn to move into a net-zero environment.
