299: The Missing Standard for Panelized Construction with Johann Betz

In this episode of the Passive House Podcast, Matthew Cutler Welsh talks with Johann Betz, founder of Christchurch-based Offsite Design Ltd and a board member of OffsiteNZ. Johann's work focuses on helping designers, manufacturers, and builders deliver high-performance timber buildings through design-for-manufacture-and-assembly (DfMA) and offsite construction principles.  The conversation traces the history of panelized construction in New Zealand, why past attempts at large-scale prefab factories have struggled without a pipeline of designs built for manufacture and assembly, and why a shared framework for offsite delivery could improve quality, reduce risk, and make Passive House-level performance more scalable and repeatable across the industry.
