A FREE lunchtime webinar on building envelope testing and what NZS 4211 and AS/NZS 4284 really tell us about performance. Learn how to make testing work for your project, not just pass it. Includes live Q&A. Earn CPD and LBP points.
Description
Does your envelope actually perform, or just pass the test?
A closer look at what NZS 4211 and AS/NZS 4284 really tell us
Testing a building envelope sounds straightforward. In practice, the standards that govern it are widely misunderstood, and the gaps between what a test proves and what happens on a real building are bigger than most people realise. Bernard Farrington has led one of New Zealand's leading test labs and has spent years watching systems pass tests and then fail in service. This session gets into the specifics - how NZS 4211 and AS/NZS 4284 actually work, where the common fallacies are, and what practitioners need to understand to make testing meaningful rather than just a compliance hurdle.
WHAT WE WILL TALK ABOUT
- What NZS 4211 window testing does and does not assess - including what it misses entirely around installation and flashings
- How AS/NZS 4284 facade testing works and why its wind zone rating is widely misunderstood
- Why negative wind pressure zones can generate forces well above what most tests account for
- What cyclic pressure and seismic testing reveals that static testing never will
- How to use testing as a genuine performance tool rather than a tick-box exercise
We’ll wrap up with a hosted Q&A, giving you the chance to dig into key takeaways and clarify your own projects.
