NCC 2022 Improving Building Performance

Australia's building standards are evolving with the NCC 2022 updates, placing a stronger emphasis on energy efficiency, condensation management, and overall building performance. Effective from 1 May 2024, these changes make mechanical ventilation crucial for maintaining indoor air quality and comfort in airtight buildings.

The new code requires exhaust systems in bathrooms, kitchens, laundries, and sanitary compartments to discharge air outside the building, helping prevent moisture buildup and contamination. Additionally, bathrooms without direct outdoor access must have exhaust systems that automatically activate with the lights and continue to operate for 10 minutes after the lights are turned off, ensuring proper airflow.

Airtight buildings offer superior energy efficiency but restrict natural ventilation, increasing the risk of condensation, mould growth, and structural damage. In cooler climates, managing condensation is especially critical to maintain building integrity and avoid health hazards from mould and dampness.

With the introduction of whole-of-home energy budgets, homes must now meet annual energy usage targets that cover heating, cooling, and ventilation. Heat recovery ventilation systems play a key role in achieving this by reducing energy loss through controlled ventilation.

At STIEBEL ELTRON, we provide advanced heat recovery ventilation systems that meet NCC 2022 standards and offer:

• Filtered Fresh Air: Continuous supply of clean, outdoor air for a healthier environment.
• Improved Indoor Air Quality: Ideal for people with asthma and allergies, reducing airborne pollutants.
• Mould Prevention: Prevents moisture buildup and mould growth, safeguarding both health and building materials.
• Energy Efficiency: Retains up to 94% of heating energy that would otherwise be lost, maximising efficiency.

We offer comprehensive support to ensure your projects are NCC-compliant and energy efficient:

• Specification Support: Tailored solutions to meet your building needs.
• Ventilation Design: Customised designs that integrate seamlessly into your projects.
• Technical Assistance: Ongoing support from design to installation, including training.

As building standards continue to advance, with more updates expected in 2025, ensuring your projects incorporate high-quality, energy-efficient ventilation is key. Stay compliant, protect your builds from condensation, and deliver healthier living environments with STIEBEL ELTRON.
