PhiusCon 2026

PhiusCon 2026, North America's premier conference on passive house design and ultra-low-energy buildings, takes place October 8-10 in Phoenix, Arizona. The event attracts hundreds of passive building professionals including architects, engineers, contractors, building scientists, and developers committed to dramatically reducing heating and cooling loads through superior insulation, airtightness, and efficient mechanical systems. Attendees explore multifamily passive house case studies, deep energy retrofit strategies for existing buildings, cost-benefit analysis, and how Passive House principles align with building decarbonization goals and evolving energy codes. Sessions address design tools and modeling software, certification pathways, supply chain challenges, and market adoption drivers. PhiusCon brings together practitioners pushing building performance boundaries to achieve net-zero outcomes, with specialized tracks for residential, commercial, and mixed-use projects. Networking events and facility tours showcase completed passive house projects.
