Ventilation in Buildings: Questions in Compliance

Managing ventilation in high-performance buildings requires more than simple air exchange rates. Experienced Designers need to integrate balanced mechanical ventilation with heat recovery (MVHR) systems that both ventilate and conserve energy.

Tradespeople must ensure ductwork is sealed to avoid energy loss and properly installed to prevent noise transmission. Building control should verify that ventilation systems perform under both peak and low-demand scenarios, ensuring air quality remains consistent. 

Do these advanced ventilation solutions comply with or exceed Clause G4. How these systems impact energy efficiency and internal moisture control.
