BASIX Certificate NSW & Energy Efficiency Reports
BASIX Certificates from $450 + GST
The Building Sustainability Index (BASIX) is a NSW Government initiative that ensures new homes meet strict energy efficiency, water usage and sustainability requirements. If you are building or renovating in New South Wales, you will need a BASIX certificate to demonstrate your project meets BASIX compliance requirements.
OnCert provides BASIX reports and BASIX certificates across NSW, helping homeowners, builders and designers meet BASIX compliance requirements quickly and accurately.

What is a BASIX Report in NSW?
What is a BASIX report?
A BASIX report assesses the sustainability performance of a residential development in New South Wales. The report evaluates areas such as energy efficiency, water consumption, thermal comfort and building design to ensure the project meets BASIX requirements set by the NSW Government.
Once the assessment is completed, a BASIX compliance certificate is issued. This BASIX certificate must be submitted with development applications to demonstrate the project meets NSW BASIX sustainability standards.
OnCert provides professional BASIX reports and BASIX certificates across NSW, helping clients achieve fast and reliable BASIX compliance.
BASIX Certificate Requirements
The BASIX certificate requirements apply to:
• New residential homes in NSW
• Major renovations valued at $50,000 or more
• Alterations and additions requiring development approval
A BASIX compliance certificate must be lodged with the NSW Planning Portal as part of the development approval process.
Meeting NSW BASIX requirements ensures new homes are designed to reduce water use, greenhouse gas emissions and energy consumption.
Understanding BASIX Requirements for Sustainable Residential Developments
The BASIX requirements criteria are established to assess the sustainability and environmental impact of residential projects in New South Wales (NSW). These criteria cover multiple facets of building design and construction, ensuring that both new homes and renovations adhere to sustainability standards. By emphasising Water Efficiency, Thermal Performance, and Energy Efficiency, BASIX strives to develop homes that are not only eco-friendly but also comfortable and economical for residents.

Location & Orientation
The placement and orientation of a building are vital for its sustainability. Thoughtful orientation can harness natural light and ventilation, minimising reliance on artificial lighting and cooling systems. By taking into account the building's alignment with the sun and prevailing winds, designers can enhance energy efficiency and thermal comfort. This strategy not only lowers energy consumption but also improves the overall living experience for residents.
Construction Type
The construction type of a building greatly affects its environmental impact. Using sustainable materials and methods can reduce embodied energy and improve performance. Key strategies include:
Utilising locally sourced or recycled materials
Implementing low-impact construction techniques
Incorporating passive design principles, like thermal mass and effective insulation, can further enhance energy efficiency and comfort.
Window Size & Type
Windows play a vital role in a building's thermal efficiency. The dimensions and style of windows can significantly impact heat gain and loss, ultimately affecting energy consumption.
High-performance windows featuring low-emissivity coatings and double glazing can enhance insulation, minimising the need for heating and cooling.
Thoughtfully designed window placements can also promote natural ventilation, further decreasing energy usage.
Landscaping
Landscaping plays a vital role in water conservation and sustainability by:
Choosing native plants
Using efficient irrigation systems
Implementing rainwater harvesting
Additionally, strategically placed trees and shrubs provide shade and windbreaks, improving buildings' thermal performance. Sustainable landscaping enhances property aesthetics and supports environmental sustainability.
Appliances
The selection of appliances is vital for energy efficiency in buildings. Choosing energy-efficient options, such as low-flow showerheads and high-efficiency heating systems, reduces water and energy usage. Homeowners can save on utility bills and support environmental conservation by opting for appliances with high Energy Star ratings. Additionally, smart home technologies can further optimize energy use and enhance the living experience.
Thermal Comfort and Other
Thermal comfort is essential in BASIX assessments, ensuring homes are energy-efficient and pleasant. Key factors include:
Proper insulation
Efficient heating and cooling systems
Passive design strategies
BASIX promotes sustainable, comfortable living. Additionally, evaluating embodied energy in materials—energy used in their production and installation—is often overlooked. Using low embodied energy materials and integrating renewable energy sources like solar panels can reduce environmental impact and enhance sustainability.
