The Passivhaus Trust is delighted to partner with the Passive House Association of Ireland, bringing the 2025 Passivhaus Conference to Belfast on 7 - 8 October.
In a changing climate, it’s time to change the norm. This year’s conference tackles the twin challenges of climate and cost-of-living head-on, showcasing Passivhaus as a practical, proven solution ready to scale. With major players like Cairn Homes mainstreaming performance-led design, and policymakers shifting gears, the question isn’t if — but how fast.
Join leading voices, fresh policy updates, and deep technical insight as we explore how Passivhaus is driving real change. Attend both days plus the site visit to earn up to 21 PHI credit points, that’s 20% of your total renewal points for a five-year period! View the full programme here. Tickets are now on sale, secure yours today!
