Passive House Community

The Passive House Community...

is dedicated to making Passive House design and construction into mainstream practice.  We are architects, engineers, developers, builders, energy modelers, material and equipment suppliers, consultants, designers, and others working to address the climate crisis through the creation of a sustainable built environment.

The Green Building United Passive House Community holds public meetings as well as trainings and events throughout the year that are discounted for Green Building United members. 

Some of our members have trained in the international Passive House system (iPHI), and some with the U.S. system,  and we remain religiously "non-denominational" and collaborate with groups like the iPHI affiliated North American Passive House Network (NAPHN) and the Passive House Institute U.S. PHIUS and other Passive House focused organizations.

Get Involved


Green Building United offers educational opportunities throughout the year, including the Sustainability Symposium and New Gravity Housing Conference. These conferences include a curated set of Passive House focused sessions that apply classroom theory to built projects from around the country and address the challenges faced by designers and contractors in the field. If interested in watching past content, please see our Webinars On-Demand library.

Education is not limited to the classroom!  The Passive House Community sponsors on-site tours of Passive House projects – some completed and certified, some under construction, providing participants with in-the-field training in techniques and technologies being implemented to meet the challenge of getting to the Passive House.  These tours included single and multi-family and commercial construction. Keep an eye on our events calendar for details.

The Passive House movement is growing and with that, the demand for trained and certified designers, verifiers, and builders is growing. Green Building United works with partners to coordinate trainings throughout the year. These courses are intensive, grounded, and collaborative. Keep an eye on our events calendar for details.


2020 Demonstration Project

We are excited to collaborate with Habitat for Humanity Philadelphia (Habitat) to further their goal of offering an
increased volume of affordable, high performance housing. Our communities enjoy unique connections between
our design and field teams, and through this project, the Passive House Community will examine Habitat’s high
performance designs, collaborate in the field, and be double-linked to the ultimate goal of single family owned,
healthy, affordable, high performing row homes. The proposed Demonstration Project challenges are to educate
our joint communities and generate an affordable passive house alternative for Habitat using the existing Oxford
Green Community Model. There is also future potential to connect “beyond the choir” with Habitat’s partners
in the health, real estate, and development sectors. Successful collaborations now could forge new joint goals over
the next several years!


New Gravity Housing Conference

Building healthy, safe, and accessible places to live that will both limit and adapt to climate impacts is a key challenge for the 21st century. This two-day event explored the tools, techniques, and practices that the building community is using to address the need for quality affordable housing that can withstand increasingly extreme and volatile weather.  The 2019 conference promises to be even more impactful with a robust program complemented by the Expo floor where cutting edge technology is exhibited by sponsoring vendors. Registration coming soon - please check out last year's conference page to learn more.
