knowledge zone - Jason Quinn
A FREE lunchtime webinar on G4 (Ventilation) and E3 (Internal Moisture) of the NZ Building Code. Learn how smart airflow strategies and moisture control go hand-in-hand to create healthier, high-performance buildings. Includes live Q&A. Earn CPD points & LBP point.
Description
Good buildings? Great buildings manage moisture.
In this punchy session, Jason Quinn explores the crucial relationship between Clause G4 (Ventilation) and Clause E3 (Internal Moisture). Discover how poor airflow leads to hidden dampness, and how better design and detailing can prevent condensation, mould, and long-term damage. From mechanical systems to passive ventilation strategies, this session will give you the insights needed to design drier, healthier buildings.
WHAT WE WILL TALK ABOUT:
-
Why G4 and E3 must be considered together in design
-
Tragic assumptions built into G4 and E3
-
Ventilation system design tips — from passive to mechanical
-
How modelling tools like WUFI and PHPP can reveal hidden risk zones
-
Real project examples that show how poor ventilation affects performance
We’ll wrap up with a hosted Q&A, giving you the chance to dig into key takeaways and clarify your own projects.
