NCC 10.8.2: Exhaust Systems and Condensation Management in Australian Homes
Condensation in homes is more than a minor annoyance—it poses serious risks to both the health of occupants and the durability of buildings. With the introduction of the National Construction Code (NCC) 2022 provisions on Condensation Management, the construction industry must now adopt a proactive and systematic approach to controlling moisture and improving ventilation. Among the leaders in this space is Alpine Ventilation, whose range of products—available through reseller Accord Air—help builders and trades meet the NCC’s new standards with confidence. Another reseller that also sells similar ventilation products is Pacific Air.
Under Section 10.8 of the National Construction Code (NCC), which addresses condensation management, Clause 10.8.2 focuses on exhaust systems. It requires that exhaust fans in kitchens, bathrooms, laundries, and sanitary compartments vent directly outdoors via a duct or shaft—discharging into roof spaces is no longer allowed. The clause also sets minimum airflow rates of 25 L/s for bathrooms and 40 L/s for kitchens and laundries, and stipulates that in rooms without openable windows, exhaust fans must be interlocked with the light switch and include a run-on timer operating for at least 10 minutes after the light is turned off.
These measures ensure that moist air is effectively removed from buildings, reducing the risk of mould growth, timber decay, and poor indoor air quality. The regulation applies nationwide across all climate zones, making compliance essential for new homes and major renovations.
Alpine Ventilation has responded proactively to these updates by developing a product range that meets and surpasses NCC 10.8.2 standards. Their offerings include high-performance exhaust fans with integrated timers, compliant ducting, and low-profile vents designed for efficient airflow and discreet appearance. All components are engineered for durability, ease of installation, and long-term reliability, simplifying compliance for builders.
Beyond performance, Alpine emphasizes quality and adaptability. Their systems suit various construction types, including BAL-rated options for bushfire-prone areas. All ducting and accessories meet relevant Australian Standards, ensuring consistent performance and energy-efficient, healthy indoor environments.
Through a partnership with Accord Air, Alpine Ventilation products are widely accessible to builders and contractors nationwide. Accord Air’s strong reputation for reliable supply and technical support complements Alpine’s innovation, offering a seamless path to compliance.
As the industry adapts to stricter building codes and growing awareness of condensation risks, compliance now means more than meeting regulations—it’s about protecting building integrity and occupant health. By specifying Alpine Ventilation systems distributed by Accord Air, builders can ensure compliance, quality, and long-term performance in every project.
