A recurring event showcasing real-world efforts to increase diversity, equity and inclusion using case study framing.

The PHN DEI case studies examine the struggles, showing lessons learned, celebrating successes, drawing new connections and revealing new possibilities. The series intends to investigate a wide variety of Passive House building industry aspects: education, professionals, ownership, occupancy, workforce, social justice, government, private business, policy, strategies, pilots and more.

The goal is to offer real world takeaways and inspiration for attendees to act on and make DEI an everyday priority in their Passive House and whole-life efforts. 

The format is short presentation followed by moderated conversation.  (attendees submit questions through chat )

The next PHN DEI event is scheduled for April 27 at Noon ET. Stay tuned for updates!
