# Passive House Accelerator

> Passive House Accelerator is the leading media platform and community hub for passive house design, construction, and building decarbonization. It publishes in-depth articles, the Passive House Podcast, PHA Live video workshops, project case studies, and Passive House Accelerator Magazine, covering the full practice of high-performance building: airtightness, ventilation, insulation, windows, mechanical systems, deep energy retrofits, multifamily and affordable housing, embodied carbon, prefabrication, policy, and the economics of building to the PHI and Phius standards.

Passive House Accelerator serves architects, builders, engineers, developers, policymakers, and homeowners working to decarbonize the built environment. Content combines technical deep dives, practitioner interviews, measured project data, and lessons learned from real passive house projects across North America and around the world, treating the PHI and Phius certification standards with equal rigor. Passive House Accelerator also convenes the Reimagine Buildings Collective, a membership community for building decarbonization practitioners.
