In this episode of the Passive House Podcast, Ilka Cassidy talks with John Loercher, Passive House consultant, architect, and longtime Phius instructor with Northeast Projects. The conversation covers how the Phius standard has evolved since 2015 as well as growing industry attention to embodied carbon, hygrothermal modeling, and materials like straw bale construction. John also reflects on his years building the Phius Alliance New York chapter, the value of regional Passive House communities, and what excites him about expanding into new climates like Colorado's high elevation and PhiusCon's move to Phoenix.
