Accelerator Partners are Passive House practitioners who share our commitment to building better, building cleaner, and sharing knowledge about Passive House methodologies with wider audiences. They allow us to reach new builders, developers, architects, and policymakers who want the benefits associated with Passive House construction (lower energy bills, a continuous supply of filtered air, more durable construction, and happier occupants!), but have yet to learn that there are passive design principles and established, performance-based building standards that can provide them.
If you want to learn how to become an Accelerator Partner, please email [email protected] to see how you can help us accelerate the wider adoption of passive design and construction.
