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, Ilka Cassidy talks with Michael Jemtrud, professor of architecture at McGill University and chair in Architecture, Energy, and Environment, about his interdisciplinary research lab's work bridging design education and offsite construction. Michael discusses McGill's Reconstruct program and the development of tools to close the "over the wall" gap between architects and manufacturers. The conversation explores how teaching students to think like "virtual framers" could give the next generation of architects a real advantage entering the workforce.
