Building Sustainability Standards, You Need to Know Before Entering 2024
                     Building Sustainability Standards, You 
Need to Know Before Entering 2024
The Australian building standards are introduced to shape the country's 
environmental footprint and address several climatic changes.
With  the  increasing  importance  of  sustainability  worldwide,  Australia  has  
established comprehensive regulations, codes, and standards to guide the 
residents to construct and operate their buildings in an environmentally friendly 
manner.
New Australian homes and significant renovations in Australia must be assessed 
against the minimum energy performance requirements stated in the building 
regulations.
These standards, codes, and regulations, including NABERS energy, NatHERS, NCC, 
WERS, and more, serve as the ultimate guide to help improve building sustainability.

NatHERS, short for the Nationwide House Energy Rating Scheme, is a scheme 
implemented by the Australian government mainly to uphold building design 
standards and make new homes more energy efficient.
● It's a 10-star rating system that gauges the home's thermal performance.
● The rating applies to the building's roof, floor, walls, and windows.
● If a house has a higher NatHERS rating, it's considered naturally comfortable 
in summer and winter and, thus, is easier and economical to heat and cool.
● The 10-star rating system determines the 'shell frame design' via NatHERS-
accredited software.
● You should know that this rating system accounts only for the home's design 
and not the household appliances plugged into the walls.
Since 2013, it's been a must for apartments in Australia to achieve an average of 
6-star rating collectively for all sole-occupancy units (SOU) and for each individual 
SOU, the rating should be at least 5-star.
With the new update, residential structures are mandated to achieve at least a 7-
star rating (an increase from the previous 6-star requirement).
National  Australian  Built  Environment  Rating  System 
(NABERS)
NABERS, abbreviated for the National Australian Built Environment Rating System, 
provides a simple,  reliable,  and  comparable  sustainability  measurement  for  
buildings  across  the commercial sector, such as hotels, offices, shopping centres, 
apartments, and more.
● NABERS energy rating assesses the building's energy efficiency, and the 
water rating evaluates the water usage and conservation measures deployed 
in the building.
● This rating system not only helps you to accurately measure, 
understand, and communicate your building's environmental performance 
but also identifies the areas for future improvements and cost savings.
● In addition to energy and water, NABERS provides a rating from 1-6 stars

Comprising the Australian Building Code and the Plumbing Code, the National 
Construction Code (NCC) sets minimum energy efficiency performance requirements 
for new buildings.
● It outlines the minimum requirements for the design, construction, and 
performance of new  buildings  and  sustainability  provisions  for  
energy  efficiency,  environmental sustainability, and water conservation.
● This building sustainability standard specifies requirements for building 
envelope design, HVAC systems, insulation, lighting, and glazing to help 
the country reduce energy consumption and greenhouse gas emissions.
Building Sustainability Index (BASIX)
The NSW government introduced the Building Sustainability Index (BASIX) in 
2004 to encourage sustainable residential development.
It's, in effect, part of the Environmental Planning and Assessment Act and was 
established to meet targets of 40% reductions in water consumption and 25% 
reduction in greenhouse gas.
● The primary purpose of the BASIX Certificate is to equip NSW with increasingly 
resilient dwellings while reducing water consumption and greenhouse 
gases.
● The BASIX assessment considers various criteria, like the building's location, 
orientation size, construction type, landscaping, window size and type, 
appliances used, and thermal comfort levels.
● Your BASIX certificate will help confirm that your building will abide by the 
JV3 Asusstsaienasbsilimty ent targets set by the NSW government.
JV3 is the alternative method to assess commercial buildings using a deemed-to-
satisfy (Dts) reference building to compare the new building's overall 
assumed energy consumption concerning their location and climate.
● The building sustainability standard applies to all buildings of Class 3, 5, 6, 7, 
8, and 9, excluding buildings of Class 2 and 4.
● During the JV3 Assessment, it's determined whether or not the proposed 
building exceeds the annual energy consumption of the DtS reference 
building.
● It's better if the proposed building doesn't exceed the DTS reference 
building's yearly energy consumption, as this allows much more flexibility 
when designing and choosing building elements.
Wrapping up it all
The term' sustainable building' has become increasingly popular worldwide, 
with a rapidly growing number of regulatory initiatives introduced into the Building 
Code of Australia.
In response to environmental impacts arising due to building development, the 
Australian government has developed several regulations, codes, and standards to 
construct and operate energy-efficient, sustainable buildings.
From NatHERS and NABERS energy to JV3 assessment and BASIX, all these 
building sustainability systems and standards help evaluate the building's energy, 
water, materials, and indoor environment quality.
