What is BASIX, and What Sustainability Updates
Can You Expect?
BASIX (Building and Sustainability Index) is
referred to as an assessment tool for measuring
sustainability associated with residential
buildings within NSW. The aim is to reduce the
adverse environmental impacts caused by the new
homes and encourage the builders to meet at least
the minimum sustainability standards. BASIX helps
promote better thermal performance, water
efficiency and proper energy utilisation. Beyond
that, it also reports on the type of construction
materials required for constructing a property,
based on which the embodied energy is then
calculated. A BASIX certificate requirements are
applied to all the NSW residential dwellings and
are a key utilisation parameter for fulfilling
the net-zero emission goal thats set to be
achieved by 2050. As of today, the BASIX
requirements are considered an integral part of
the overall residential property development
process. If you are about to construct a property
anytime soon in Australia, you might need to be
aware of what BASIX is and what some of the
sustainability updates on it are for you to
adopt. Read along this article till the end to
find out!
What is the Significance of the BASIX Certificate?
2

• BASIX is the concept that the NSW government
  introduced in order to ensure that the homes
  being constructed are designed in a manner such
  that
• They use a lower amount of potable water.
• They are responsible for lowering the greenhouse
  gas emissions
• Adopt the set targets associated with water or
  energy reduction for specific units or dwellings.
• A BASIX certification is a mandatory requirement
  for all new residential developments, and
  complying with the rules is of utmost necessity.
  Some of the types of properties that would need
  BASIX report before the construction work is
  approved are
• Dwellings for single or dual occupancy
• Townhouses
• Villas
• Multi-unit or unit developments
• Residential alterations worth 50,000 or more.
• Construction of outdoor spas or swimming pools
  with water capacity demands of 40,000 litres or
  more.
• Upon obtaining a BASIX report and certificate,
  you can ensure that the new residential property
  that you are about to construct has passed the
  governments policy on reducing the over usage of
  energy and water in your house.
• It also means that you will be saving a lot of
  money on your utility bills.
• BASIX in NSW is the first ever conduct that is
  proposed in Australia for implementing strong
  sustainability efforts.
• It has been in existence since 2004 and has been
  helping the nation improve its sustainability
  quotient around residential developments.
• As of 1st October 2023, new standards were
  proposed for BASIX that align with the NCC
  (National Construction Code) of 2022. This
  alignment is mostly in the energy and water
  efficiency domain.

What Changes Have SEPP Proposed With Respect to
the Use of BASIX for Residential Construction?
3

• As of 1st October 2023, SEPP (State Environmental
  Planning Policy) was implemented and is
  considered the key initiative for the NSW
  government to achieve the zero emissions goal by
  the year 2050.
• The entire industry had enough time to implement
  the clauses of this policy, as the draft was made
  available back in 2022, with the commencement
  date as 1st October 2023.
• Some of the legislative changes that SEPP has
  proposed in accordance with BASIX for residential
  property construction are
• The BASIX standards will be updated and
  incorporated for all forms of residential
  developments.
• Sustainability provisions will be implemented,
  even for some of the non-residential
  developments.
• Introduce specific requirements for the
  residential or non-residential developments for
  calculating and reporting embodied emissions
  associated with different construction
  materials.
• Since 1st October, the BASIX standards are now
  being implemented through SEPP, and they will be
  applicable for almost all types of residential
  dwellings or properties, as stated in the prior
  section. To give you a general perspective, any
  house construction or renovation project that
  crosses the budget of 50,000 will need the BASIX
  certificate for an approved approach.
• Some of the other changes made to the BASIX
  standards in accordance with SEPP are
• SEPP has updated the thermal and energy
  performance standards set by BASIX. In
  accordance with the change, the set standard for
  thermal performance is now improved from the
  average 5.5 to 6 or 7 NatHERS rating.
• The improved standards on energy efficiency are
  also promoting an increase of 7-11 in the
  reduction of greenhouse gas emissions.
• Such changes made to the BASIX standards by SEPP
  are applicable to almost all residential property
  constructions, except the homes that are in
  specific climatic zones, such as NSWs North
  Coast, or apartment buildings with up to
  5-storeys.
• Furthermore, SEPP didnt bring up any changes
  associated with the water standards for the
  residential constructions.
• All the homebuyers who signed a development
  contract for constructing a duplex or house
  before 1st October 2023 are allowed to use the
  prior BASIX standards without the need to invoke
  the new standards.
• For professional assistance, you can always
  connect with reputed BASIX consultants.
• The tool is also set to experience an update, and
  a materials indexing feature is being added for
  people to be able to measure the embodied
  emissions.

It means the property developers will now have to
measure the amount of greenhouse gas being
generated during the transport or production of
various construction materials. How these
Increased BASIX Standards will Help the
Common Residents? BASIX standards are now
revamped, and it would make your homes a bit more
comfortable than it was in the past. It is
because your reliance on the cooling or heating
technology will be reduced. This initiative of
obtaining BASIX certification before constructing
a residential property is implemented to scale
the current sustainability standards, especially
for new developments. Take the help of the BASIX
consultants and let them help you cope to meet
the higher standards set by SEPP. From a
perspective, you must know that adopting these
higher standards would help you save around 1070
every year on your energy bills. There are a lot
of other benefits that might not be directed to
you personally but to the environment as a
whole. Therefore, take the help of some of the
industry experts and prepare a design for your
new home that would meet the new BASIX standards
and promote more sustainability than what is
currently being implemented. Bottom Line As per
the statistics are concerned, so far, BASIX has
helped prevent greenhouse gas emissions, measured
at around 12.3 million tonnes. The updated
standards by SEPP are expected to save more than
150,000 tonnes of these emissions every year. You
would definitely be saving a lot of money in the
long run, but meeting the updated BASIX
certificate standards might come at some upfront
cost, which is worth the value. Take the help of
professionals to help you get a proper report
using the BASIX standards and guide you with an
efficient design to meet them.
