What is a BASIX and do I need one?
BASIX (Building Sustainability Index) is a sustainability assessment tool used by the New South Wales Government to ensure new homes, renovations over $50,000, and swimming pools over 40,000 litres meet specific standards for water efficiency, energy use, and thermal performance.
Do I need a BASIX certificate?
If you're planning a custom home or renovation project in Newcastle or Lake Macquarie, you'll likely need a BASIX certificate. Both Newcastle City Council and Lake Macquarie City Council require a BASIX certificate as part of the development application process.
Why is BASIX important?
BASIX helps reduce the environmental impact of residential developments by promoting sustainable building practices. It ensures that new homes and renovations are energy-efficient, water-efficient, and have good thermal performance, contributing to a more sustainable future.
Examples of BASIX Requirements:
Windows: High-performance glazing, such as double glazing for living areas and low-E (low emissivity) glazing for bedrooms, is required to improve thermal comfort. Proper shading, like external shading devices, is necessary to reduce cooling loads.
Bathroom Items: Low-flow fixtures, including showerheads, taps, and toilets, must be used to reduce water consumption. A minimum 2,000-litre rainwater tank is often required to service toilets, laundry, and garden irrigation.
Insulation: Minimum R-value (thermal resistance) requirements for external walls, roofs, ceilings, and floors are specified to ensure good thermal performance.
Energy Efficiency: High-efficiency hot water systems, such as gas instantaneous or electric heat pumps, and energy-efficient cooling and heating systems are encouraged. Alternatives like ceiling fans or solar options are recommended.
Water Efficiency: Significant portions of the roof area must be connected to rainwater tanks, and water-efficient appliances and fixtures should be used throughout the home.
Coastal Considerations for Newcastle:
Given Newcastle's coastal location, there are additional factors to keep in mind:
Salt Exposure: Use corrosion-resistant materials for exterior features, such as stainless steel or coated aluminium, to withstand salt air. Regularly inspect and maintain your home’s exterior to prevent salt damage.
Weather Conditions: Design your home to withstand strong coastal winds and high humidity. Proper ventilation, moisture barriers, and water-resistant materials are crucial.
View Maximisation: Take advantage of coastal views with strategically placed windows and outdoor living spaces. Position your home to maximise natural light and capture prevailing breezes for natural cooling.
Thermal Performance: Use high-quality insulation and consider double or triple glazing for windows to improve energy efficiency and noise insulation.
Environmental Regulations: Be aware of local coastal management plans and regulations that may affect building permits and approvals. Incorporate sustainable design principles to minimise environmental impact and comply with BASIX requirements.
Landscaping: Use native and salt-tolerant plants for landscaping to ensure they thrive in the coastal environment. Implement erosion control measures to protect your property from coastal erosion.
