In this episode of the Passive House Podcast, Michael Ingui talks with Tomás O'Leary of the mosart Group about scaling Passive House across massive residential developments in Ireland and the UK. Fresh off a tour of Cairn Homes' Passive House neighborhood outside Dublin, Tomás shares the approach behind delivering certified Passive House at scale — from early benchmarking and training contractors directly, to building a team of certifiers with a direct line to the Passive House Institute. The conversation also touches on post-occupancy monitoring, tenant feedback, and Tomás's upcoming visits to Massachusetts and New York this October to share lessons with US developers and architects.

In this episode of the Passive House Podcast, Mary James is joined by UK-based architects Dominic O'Riordan and Alan Budden, both Passive House designers who opened their homes for the UK's Passive House Open Days during a record-breaking heat wave. Dominic and Alan discuss how their buildings performed under extreme heat, the shading strategies they wish they'd fought harder for at planning stage, and why attitudes toward mechanical cooling in the UK are shifting fast after decades of treating air conditioning as unnecessary.  EcoDesign Consultants: https://www.ecodesignconsultants.co.uk/Article mentioned by Zack: https://www.nytimes.com/2026/07/01/opinion/heat-wave-europe-america.html?unlocked_article_code=1.xlA.5iqJ._hKPg0bjq_M_&smid=url-share Join us on the Reimagine Buildings Collective: https://collective.reimaginebuildings.com/ Thank you for listening to the Passive House Podcast!

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. https://www.offsitedesign.co.nz/ https://www.osm3604.nz/ Join us on the Reimagine Buildings Collective: https://collective.reimaginebuildings.com/ Thank you for listening to the Passive House Podcast!
